    I do Own a M1911 (WW2 Build by "Union Switch and Signal") but I don't think I will have a 'conversion' made for it. It has Sentimental Value as is. My Late Father taught me Handgun Target Shooting with it.

    I also have a Very difficult to use accurately Lathe we Bought used way back in the 1960s. It was used by the Previous owner for production of Abrasive items and not kept Clean so it now has about a .006" dip in the Bed near the Head Stock that is difficult to avoid for machining small items.

    I Recently Acquired a used Craftsman Commercial 12"x36" Long Bed Lathe that is slowly undergoing a major rebuild due it having been 'caught' in a Shop Fire in the Previous owner's shop ($300 purchase and it was Covered with Melted Roofing Tar embedded with grit and the top head stock cover had a portion softened and sagged down over The Back Gear / Under-drive Pully).

    Depending upon how accurate the Craftsman Lathe turns out I may replace the other one in my Home Shop (set up by My late Father in our Garage).

    Since I live in Southern California, I have to 'Live with' and 'deal with' the Federal, State, County, and City government's continuing assault on our 2nd Amendment Rights by "the death of a thousand cuts" continuing 'nibbling around the edges' of Legal gun Ownership while Ignoring the Illegal and Criminal uses. It appears to me that the "Anti-Gun Activists" are "in Fact" "Pro-Crime Activists" as evidenced by the Laws they Propose and get enacted.

    Yesterday a friend and I spent a Day at the Shooting range with a Chronograph, here is the Report of our results:

    Chronograph results of Load Testing on Tuesday August 16th 2016.
    At “Angeles Shooting Ranges”.

    Instrument used: ‘Shooting Chrony F1 Master’ with printer.

    Test Firearm:
    Ruger New Model Convertible Single Eight in 25ACP and .25ALRM Cartridge Chambering eight shot Revolver with 10-5/8” barrel (~12” Muzzle to Breech/Recoil Face.

    Test Setup:
    Positioned on “Handgun" Firing line in front of Permanent Target Frame about 5 yards from long Bench Type Firing line. Bench height about 38 inches.
    A Stool was used for the Testing as a Seat for the ‘Shooter’.
    Chronograph was Set up on a Tripod about 5 feet forward of the Firing Line. The Remote readout and printer were positioned on the Firing line bench.
    The Printer and Chronograph were operated on Internal Batteries.
    Altitude = ~ 1,680 feet Above Mean Sea Level, Temperature ~100 Degrees F.

    Test Results:
    Comparison run employing “Prvi Partisan” (PPU) Factory Loaded (Made in Serbia) .25ACP 50Grain FMJ-RN ammunition manufactured under CIP Regulations and Controls.

    Conclusion: for the Same Charge Weight BE-86 Generates a lower Peak Pressure than Bullseye under the same conditions.

    SUMMARY

    Recorded data Results seems to vary from Calculated Values by Bilateral amounts. It is probable the sample size used is not adequate. It is also probable that the Charge Weights vary due to the Imprecise Scale used for the Charge Weight Resolution desired.
    Due to the Low Value Charge Weights, in the range of 1.3 to 2.7 grains, and the marked Resolution of the Scale used, 0.1 grain, the interpolation of charges to 0.01 grain +/-0.05 grain is less than the observed variation in measured performance.

    The instrument used has a measuring base of about 1 foot and four digit readout resolution but the full Accuracy and Resolution Specifications are not known at this time.

    The factory Ammunition tested for comparison measured about 2.1% lower out of this 10-5/8” barrel compared to factory Test Barrel length of 2”. This is quite low compared to similar Barrel lengths tested By “Ballistics By The Inch” using a Single Shot Handgun with a Locked Breech and sealed length Barrel (no cylinder gap). They found a 10” barrel yielded Velocities about 28% increase in measured MV.

    How much The Ambient temperature, and the temperature of the Instrument, which was in direct Sunlight, affected These Results is unknown at this time.

    Overall, The confidence level in these results is low due to the reasons state in the summary but they ARE the Results obtained and recorded.

    Further thoughts and comments on "the first Range results with a chronograph" post of August 17th post:

    A. The Comparison of "Published Technical Specifications" of factory .25ACP, which are Based upon testing Using a 2" long Barrel, and the chronograph Results of firing in a Revolver with a 10-5/8" barrel hint that the loss from the Cylinder Gap venting may result performance similarity between the Two conditions as the Percentage difference seems to be less than the Expected Variations between Factory Ammunition Lots.

    B. The reported "hand load #1" (2.7 grains of Power Pistol and 50 grain FMJ bullet) seems to hint at a 7.6% drop between Calculated and Measured Performance. This is Probably due to the "QuickLOAD" software apparently not having an adjustment for loss from the Cylinder gap. Perhaps using 11" for the Barrel length instead of 12" would mostly compensate for the Gap 'error'?

    C. The reported Hand load(s) #2 (Various ladder Bullseye charge weights and 63 grain Lead bullets) appear to indicate a gain in velocity for the Actual performance ranging up to about +15% in one case (nominal 1.43 grain charge) and ranging down to a low of -0.85% (nominal 1.53 grain charge). Perhaps the difference between FMJ and Lead bullets filing of the Cylinder Throat, Throat to Forcing Cone, and final Barrel dimensions is in play here.

    D. The Ladder Sequence seems to indicate a charge of Bullseye of around 1.77 or 1.80 grains yields the most uniform velocities measured (ES of 60 and 54 fps respectively) with this bullet in this Case size.

    E. However, there is still the Problems I have in Accurately measuring charges weights at 0.01 grain interpolations of these low charge Weights (under 2.0 grains total weight). Normal procedures to measure small weights is to use a Scale with a resolution at least four times Finer than the the weight increment desired. in this case 0.01 grain accuracy would indicate a needed Resolution of .0025 grains or Finer.

    F. For the time being (last two weeks of August) I am not able to do any more testing due to the Chronograph Screens needing replacements. which need to be ordered when I again have some Discretionary Spending funds available. Perhaps I will be able to proceed in September, but that is 'Iffy" as I have Fresh Bills that will again come due in September that were not needed in July or August (example: House Earthquake and Liability Insurance renewals).

    Slowly getting ready for another Range session to use The Chronograph.
    I now have replacement screens and Rods to replace those "shot" during the Last Session.

    I am Loading up another Set of "Ladder Sequence" Cartridges to test.
    One set is already loaded, some ".250ALRM" Cases with Lead bullets at 1.395" COAL.
    Another Set is in the Works, ".25ACP" with 63 grain Lead Bullets and employing BE-86 Propellant.
    I don't yet Know what else I will prepare for testing, somewhat dependent on how soon my gunsmith finishes my third Ruger Cylinder or my Stevens Model 44, Converted to CF, rifle.

    Received My New "'25 Magnum Auto FIN" chamber reamer Monday shortly before the Presidential debate Started. I will check It for dimensions before I take it to my Gunsmith.

    The New PTG ".25 Magnum Auto. FIN Reamer does cut a usable Chamber, i made a "dummy chamber in a Blank die body i had on hand.
    The Reamer, along with a Rim counterbore Tool to fit the .22 Hornet Parent Rim diameter, my Dummy chamber, and a Replacement 8-Shot Ruger .22-MAG Cylinder for Rework went to My gunsmith and are in his line to get done.

    Today I placed Orders with PT&G to get a "6.35x28.6mmSR Stewart" Replaceable Pilot Finish Chamber Reamer, Two .25 Cal. Pilot Drilled Blank Die Bodies, Two .30 Cal. Pilot Drilled Blank die bodies. and sets of Bushings for .25 Ca. and .30 Cal to use in reaming the Die Bodies.

    Now I Wait. Patiently I Hope.

    Best Results,
    Chev. William

    Lee sent me a replacement "Opened" .25ACP Sizing die made to size to .288" Diameter so now I can resume three stage Sizing of 5.7x28mm cases down to .276" body diameter. It has Been a LONG wait for Lee to resume working on .25ACP Sizing Die Production (since last February!).
    Due to Property taxes and other bills I cannot, at this time, order additional "opened" Sizing Dies for Spares.

    PT&G is still working on my last Reamer order.

    Happy New Year 2017!
    I presently have two 8-shot Cylinders awaiting Re-cut of their chambers at my gunsmith along with a Stainless Steel (SS) 6-shot cylinder the shop is trying to get Ruger to Exchange Without Sending the Revolver in for fitting by Ruger.

    The SS cylinder has a DEEP "pit" opening in the Rim rebate and getting bigger in the outside chamber wall, it shows not evidence of firing but has a Ruger "Electric Pencil" serial number on the front face, indicating it went through Ruger somehow.
    The 6-shot Cylinder (the replacement) is intended to be Re-cut for .32 Long Colt Cartridges and be used with my Second Ruger Single Six Revolver which is in .32 H&R Magnum chambering. This will give me two 'convertible Ruger Revolvers, one in .25ACP parent and one in .32 H&R parent.

    Lee Precision has told me via email they can make a Forming Die with a Carbide Ring to Swage .32 S&W/.32 H&R/.327 Fed. Mag. cases down to about .326" body diameter so this month I think I will order one as a 'First Stage forming Die to ease Pressure on my Existing Carbide Hollywood die.

    Other Things have also been going slowly this Winter due to cold and wet times and Waiting for replacement tooling. I did finish forming on another 100 .25 caliber parent cases and 100 Parent .32 caliber parent cases.

    I also now have a finished Cartridge Belt and Holster for my Ruger Long Barrel Single Eight Revolver. the belt started out as a 'Blemished Triple K Western Drop Holster Belt with .22 Caliber Cartridge Loops. It now has additional Loops; and all are suitable for my .25 Cal. Long cartridges.

    No Further Progress on my Rifle Projects through the end of Last Year so patience is a Virtue being exercised here.

    Best Regards,
    Chev. William

    It is now Mid July 2017 and Very Little Progress has been made on my Projects due to Scheduling/Financial/health/and Pet Dog Problems of Late.

    In beginning of June I was Able to Buy a lot of Once Fired 5.7x28mm Brass at a Gun Show in Costa Mesa,CA (~2000 cases for $70.00 turned out to be 1852 by Actual count of 5.7x28mm Plus some Extra other caliber cases).
    So now my 'Back Stock' of 5.7x28mm to be Processed is about 3000 cases with about 800 mostly Processed into 'Parent' 6.25x32mm SR or Shorter ones.
    An additional ~1000 of my "Back Stock' have been De-capped and Boxed awaiting my swaging Process. The Remainder still have not been De-capped yet.

    Due to my gunsmith Having Lost his wife last year, and His advancing age (with its associated Problems) and his Movie work Taking him away from the Shop, I have not Seen any progress on my Projects with him.

    I have Carried the !890 Winchester "Putter Project" Conversion to .25ACP about as far as I can without My gunsmith's assistance so it is waiting.

    My own Mobility has shown an Aging Decrease in the Last year so it is more difficult to get to the Range with my Guns and gear to shoot, let alone Test Loads via my chronograph.

    My Refurbishment Project of The Long bed Craftsman Commercial 12 inch Lathe has also hit a scheduling Problem as it is in a Friends' Special Effects Shop and he has Been Busy The Last many months on Movie and Commercial Projects and his Schedule is too crowded to allow me time to "putter" in his shop.

    The friend Who Bought my Black 2006 dodge Dakota to return it to service, after it was "Totaled" in December 2015, seems to have both Done the repairs but failed to do the Title Transfer so Now I received A Mailed 'notice of violation and Liability as he was caught driving it without current Paid Registration or Title. Now we BOTH need to get to a DMV office To Get the Paperwork straightened out then to the Court to get The Ticket Resolved. At least the CHP was Kind enough to ticket him but did not Impound The Truck at that time, it is now parked on my Property again.

    My own Employment has not been forthcoming so far this year as I have not received Any "Work Calls" through My Union dispatcher System. as I am 74, it may be a 'Movie Industry' reluctance to hire Older Temporary Workers problem. This Industry Seems to have a Strong Bias toward the "Youth End" of the Labor Market.

    The Black 2006 Dodge Dakota is Now Finally registered in my Friends Name!
    Now He has to Get time and Money together to get the Final Repairs needed To Get an Emissions Test Successfully Passed (Transmission Error Codes Cause a Emissions Test FAIL!) by California CARB Rules.

    on Another pair of Notes:
    First - I completed De-capping al The 5.7x28mm cases on hand (about 3000 total) and Started Swaging a Lot of about 400 Cases down to .276" body diameters.

    Second - I bought a New Lee Universal Expander Die and Set About Modifing It for a Dedicated Expander die for my 5.7x28mm case reforming process.

    Just Tried out my New Lee "Universal Expander" Die with the Small Cartridge Expander stem Turned To .250" diameter. Outstanding results! The Die / Stem expands the Neck/Shoulder of 5.7x28 Cases Enough so the Swaging Process Removes the Felt evidence of The Prior Neck and Shoulder Junctions. My Prior Expander was a .2500" Drill Blank machined With a tapered end and Chucked in my Bench Drill Press for Use. It left a Slight Felt difference in diameters in the Area of the Neck and Shoulder Joints in my Swaged cases.

    Very Happy with this new Modified Expander and Die!

    A Pair of Modified Tools:
    First, A Lee Champfering Hand Tool that is TOO TALL to use with .25ACP Cases was Shortened in a Lathe to allow holding the case and champfering the Outside edge of Mouth.


    Left to Right: .25ACP Case; Stock Lee tool on a .25ACP Case; Modified Tool on a .25ACP Case.

    And Second, A Lee Universal Expander Die Small Case Punch is Modified to make a .250" Diameter Case mouth Expander.


    Left to Right: Stock Lee Small Case Expander insert; Modified Lee Small Case Expander Insert with Lathe turned shank of .250"/.240" diameters.

    An Update on my development projects:

    JGS Precision delivered my New Cylindrical Body .25ACP Finish Chamber Reamer and I have delivered it to my Gunsmith so he can cut chambers in one of my 8-shot Blued .22 Mag Replacement Cylinders.

    I completed reforming the batch of 400 cases and started another batch of 400 through my Reforming process.
    Of the previous 400, 150 have been trimmed to .960" case length, 100 trimmed to 1.055" case Length, and 100 trimmed to 1.125" case length with the remaining 50 left at the as formed Length for future trimming as Needed.
    50 of the .960" case length have had their rim Diameter reduced to fit my 1890 Winchester CF Conversion Project magazine tubes.

    The .25 Automatic Long Rifle Cartridge is now listed on Ammoguide Interactive (ammoguide.com) as Cartridge Number 1011 in their Cartridge Master Data Base with Case drawing , cartridge specifications , and descriptive write up. So far No Loads have been Posted to it, but that may change in the near future.

    Bought a Lyman Hand Small primer pocket Uniformer Tool last weekend and have been experimenting with it on my reformed 5.7x28 cases with interesting results.
    The tool Does Cut the Bottom of the Primer pocket Flat and square corner, actually a very Small radius corner,with multiple turns of the tool.

    Next I chucked the case in a Portable drill Motor and tried power 'uniforming' wiht mixed results. Yes the Pockets came out uniform; but the tool sometimes 'grabbed' and the case turned in the chuck, partially removing the Polymer coating.
    No other problems were discovered in the 16 cases I finished.

    I received my order of Matt's Bullets Saturday and plan to open the box Wednesday.
    This is a 1000 piece order of Lyman #257420 65 Grain Nominal bullets and 1000 piece order of Accurate Mold #311090A 90 grain nominal Heeled Bullets.
    The Heeled ones were ordered Lubed and will have a film of Lube covering The Heel and filling The lube groove in the heel. I have found the 'film' scrapes off as the bullet is seated in my .32 Colt sized cases. I then Crimp them using a Collet Crimp die I bought from Old West Moulds.

    The Nominal 65 grain Lyman#257420 Bullets "Lubed And Sized"{ to .257 weigh between 73 and 74 Grains; which is about 112% of what Lyman advertises this Mold to drop.

    This is also about 150% of Nominal .25ACP bullets!

    a short Update:
    I have received two JGS Precision Custom Finish Chamber reamers, a .25ACP WS #1 and a .25ALR WS #2, and handed them along with two Aftermarket 1144 Alloy Steel 8-shot ".22MAG" Cylinders to be reamed and chambered for the two cartridges respectively.

    Of The 1000 Matt's Bullets Cast Lyman 257420 Bullets received, I have sized 500 to .250" diameter for my experiments.

    These roughly 74 grain bullets are about 150 percent of what commercial .25ACP bullets, and what commercial cartridges are loaded with. I am guessing these would Qualify as "heavy for Caliber" bullets in either .25ACP or my wildcat .25ALR so perhaps a revisit of the H-110/W296 propellant use question may be in the future.

    I bought 200 empty Jagemann Stamping .25ACP Brass and find that the Lot i got seem to need trimming to around .603 for consistent loading use (63% are .603"-604" length as received).

    I bought 500 empty PPU .25ACP cases through Graf & Sons and found the lot seems to measure .617"-.619" case length and .274" case diameter. Significantly different from my previously purchase of PPU empty cases; which measured .612" length and .278" diameter.

    Frustrating when I was hoping for MORE of the .278" diameter New cases for my testing needs.

    Whether here is Dry, Windy, and Cool; which is making work on reloading inmy Outside 'shop' Very Uncomfortable.
    It also has raised the Problems of 'Wildfires' in the area of Southern California as noted in the News, and will drive up my Utility combined bills due to added Watering of my Shrubs and Trees to keep them Green and fire resistant.

    The winds have torn the tent cover over my patio so I will be needing to change it out if it rips further soon; otherwise I will wait for warmer and calmer whether, perhaps in the spring.

    Now about a "Quarter Past 2018" and perhaps time for an update on my "Progress".

    1. My collection of Finish Chamber reamers now include PT&G Tapered body reamers for:
    - .25ACP (SAAMI max case length = .615");
    - 6.35x26mmSR (max case length = 1.056");
    - 6.35x28.6mmSR (max case length = 1.125);
    - 6.35x32mmSR (max case length 1.260");
    - and .250ALRM (max case length 1.250") Wildcats.
    They also include JGS Precision Cylindrical body Finish Chamber Reamers for:
    - .25ACP WS #1 (max case length = .615");
    - .25ALR WS #2 (max case length = .960");
    - .25MACP WS #3 (max case length = 1.056");
    - with .25ALS WS #4 (max case length = 1.125") on order.
    The Next one to be ordered from JGS will be the .25ALRM WS #5 for a case length of 1.250".
    Additional reamers in .32 also now owned.

    2. My Gunsmith is intermittently working on the several 8-shot Aftermarket Ruger Convertible Single 'Six' Cylinders to convert them to the Cylindrical Chambers for my Various 'Wildcats' as I found the tapered chambers allowed the Fired cases to "Bulge' out to fil the taper near the Web top wall junction leaving the cases with a .280"=.283" area just forward of the Web tha tI have to resize for reloading, working my cases excessively.

    3. My Rifle Conversion Projects are waiting for my gunsmith to finish some of my presently 'in the Works' projects before he will accept any more.
    These waiting for submission include:
    - a Marlin model 56 conversion to CF and .25ACP;
    - a Winchester Model 1890 conversion to CF and .25ACP-.25ALR interchangeably;
    - a 30-06 M1 Rifle for fitting with a "M1D" type Scope mounting base;
    - and a 'Less than Pristine' Stevens 1915 "Favorite" action For Rework to CF with the Receiver Pivot holes Bushed out to provide better Support for the Pivot screws/pins as an Experiment.

    My Idea for the Stevens 1915 receiver is to make and install 'Shoulder Bushings', with the shoulder on the inside of the receiver walls, to add support where the original leave the pivot screws/pins unsupported between inside wall and the Breech Block especially.
    I am thinking either Silver Braze or Welding them in place and then finish surfacing and reaming for new pins with retainer screw similar to the design of the Model 44 action.

    This, plus careful fitting of the Breech Block to solidly contact the rear shoulders in the receiver when closed in Battery and adding semicircular support tabs to the Lever to fix the Breech block in the maximum possible support is my intent.

    This Modified action will be used with a full Octagon "J. Stevens Arms" marked '.25 Stevens' Long RF Barrel I have with beautiful rifling and bore.

    Note / update:
    i received an order of Hornady .25ACP empty cases form a Sale offering at Midway Supply and the one I measured so far is encouraging; it measured .277" body diameter and .615" case length. In the next few days i will do a full lot 'Receiving Inspection" on them to see how well they fit my needs for 'maximum dimension' Cases for my Testing.

    Also, I am planning to 're-purpose' the undersize .25ACP cases I have by Swaging them down to .246"-.248" body diameter to use as Center Fire .22 Long Rifle equivalents following the pattern of "NoZombies" design for his '.22 Ladybug' cartridge design discussed on this Forum.

    To that end, I have received a series of 'standard size' Hardened (Rc51) Steel Drill Bushings running from .250" ID to .277" ID, most of 1/2" OD and Length. One .250" diameter is also 1/2" OD and over 1" length to use in a seating die design.

    Next, I will Order some 4150 or 4140 Alloy Steel Pilot drilled Blank Reloading Die bodies to machine into forming, seating and crimping dies for the Equivalent ".22 Ladybug" cartridge. PT&G Blanks are looking good at about $20.00 each, although they may be too Long for easy use as Forming Dies as i will need to use a Punch from the top to remove the case from the Die as it is run in to the top of the rim in the forming process.

    Where did you find the Hardened Drill bushings? All I've been able to find are sized to standard Letter, Number or factional sizes. I haven't been able to find decimal sized bushing. Some of the standard sizes will work of course, but it would be nice to order the exact decimal sizes I need. I'm converting several different cases for .25, 30, 40, 45 and 50 caliber cartridges, mostly obsolescent stuff.
