Dean I'll post any loads I work up using .357Mag cases.
Bob
Cool, thanks.
I won't be able to use .357 cases with the RCBS 35-200. Even in a .38 case, seated to the crimp groove it's about .090 over max length for a .357 mag. I'm going over to his house tonight with some dummy cartridges to see if it'll still cycle. Won't know till you try. Some levers are more forgiving than others when it comes to OAL.
It works! Seated deep into the crimp groove it cycles his lever gun just fine. Seated shallow on the crimp groove tends to hang a bit. I'm tempted to seat a little deeper and slap a taper crimp on that puppy.
We stuck on in his GP100 and the nose of the boolit is almost flush with the edge of the cylinder. We're gonna try some in his pistol too!
Well I loaded the Lyman 358430 201 gr bullet in .357mag cases with 5.5 gr of Unique under them and fired with a Win SPMag primer.
Here are the results of 10 rounds fired over my F1 Chrony. Temp was 21C
Cases: Mixed
OAL 1.615"
High 962fps
Low 937fps
Avg 952fps
SD 7fps
Ext. Spread 26fps
Avg PF 191
Recoil was almost identical to shooting 200 gr boolits out of my 1911 at the same PF. Compared with my loads using 158 gr boolits the recoil was less snappy and more of a push with much less muzzle rise.
I am not a target shooter but the load certainly seemed to be accurate enough out to 25 yards. At 15 yards the hole just got a bit bigger with every other shot from a rest.

Those #358430s can REALLY shoot. Those velocity ratings are right fine, too. Single-digit SDs are nothing to sneeze at, and sub-1% in the bargain. GOOD LOAD.
OK I went to the range today with .37cases loaded with 5.3 gr of Unique. The only bad news was I discovered I had loaded the rounds to long for them to cycle in my Rossi. Stupid here, didn't check before leaving the house so all rounds tested had to be loaded one at a time from the breach. Well that isn't the dumbest thing I have done in my life and with that little misadventure aside here are the results.
5.3 Gr Unique
Cases R&P Nickle Brass
OAL 1.630 (Should have been 1.590 to cycle in my Rossi)
High Vel 1089
Low Vel 1063
EXT Sp 26 fps
SD 8!
I never did any accuracy tests other than to go at a plate at 50 yards ding ding ding and out to 100 yards bullet drop was noted. One thing I have noted shooting at plates and poppers with this boolit was, it has energy behind it, and logic tells me it has killing power. Not that this is a factor. For me living in "Canada the Good" hunting is not allowed using a handgun BUT for Black Bear protection loaded a little heavier this old boolit will do very nicely if .357mag revolver is what you have on your hip.

ps Temperature was in the high 90's and hotter down at the range. I will do some accuracy tests once it cools down a bit using the Rossi.
I've been running #358430 for 30+ years, and whether at 700 FPS from the Webley 38/200 or at 1350 FPS from my BisHawk--there is some definite thumpus maximus getting transmitted by those heavy-for-caliber slugs.
Well next week-end I have an IPSC Qualifier and Steel Match to attend. I decided to risk ridicule and shoot IPSC with my GP -100 using minor loadings of 3gr of PB under my 200 gr boolits loaded in 38spl cases. Should be fun. I have 9 speedloaders ready to go. Can you imagine....
In any event should be a boatload of fun. The following week we are shooting a postal match and I have to switch to a bottom feeder as I have already shot the IDPA match with my revolver. Ah to be inept in many disciplines. Age has it's advantages.....no ego to worry about.

Inept......hardly.
Lyman #358430 was impressive from Day 1 for its intrinsic accuracy. This wasn't and isn't a fluke, its accuracy has "held" through dozens of 38 S&W--38 Special--and 357 Magnum revolvers over the many years I have cast with the mould. If the design has a "flaw" in the scope of modern thinking, it would be its dome-shaped meplat/point. Such a design is not thought to transmit shock or cavity crush as efficiently as the flatnose or SWC form, and there may be some truth to that. My solution to that issue has been to cast 20 of these bullets as soft points per the BruceB Method, in hopes of inducing some expansion in game or vermin. At slower velocities, #358430 shows pretty reliable tendency to tumble after critter contact. At Magnum speeds (1000 FPS+) the bullets seem to drive right through, and the quarry gets anchored humanely (jackrabbits, mainly) despite the bullet's less-than-ideal nose form.
Al, i have bumped a flat nose on mine with no degrading of accuracy. I have yet to see them hit anything but paper.
Funny thing about killing power Al. I know of no animal, human or otherwise that runs around long with a bullet hole through their lungs, pelvis or brain no matter how that is achieved. Lots of theory conducted on gelatin blocks on how jacketed bullets do so much more damage but round lead balls did a number on our General Brock back in the day and I suspect the modern day version in the form of a 358430 would be just as effective. I know it works well on IDPA/IPSC targets and steel plates. :mrgreen: Off to the ranger to sight in my 686 I use as back up to my GP 100.

Interior ballistics and exterior ballistics are hard, exact sciences--terminal ballistics is at best a poorly-understood art form in cahoots with wishful thinking and hopeful marketing. I am NOT a member-in-good-standing of the Facklerite Fraternity......nor am I an enthusiastic Jello Shooter. I do think bullets have improved substantially over the years I have been involved in the shooting sports, but The Magic Bullet for small arms has not yet been birthed--and may never be. For game-taking and self-protection, it is difficult to find a better, simpler, and more reliable projectile than an accurately-placed soft lead bullet.
Holes kill stuff.
Yes. And bigger holes kill stuff better/faster. This bit of common sense rang true for illiterate mountain men, and remained constant for centuries until people in lab coats or suit coats that don't get shot at much took charge of the caliber assignments and issuances. Modern thought dictates that those with the least likelihood of requiring the defensive tools have the greatest input on their selection and description.
True, but you can shoot a person more than once.
Yes, and the small-bore service calibers that predominate lately certainly incentivize that approach.
"Deputy/corporal--why did you shoot the assailant 16 times?"
"The slide/bolt locked back."
I plead the fiz'ith
Worked up some loads with 4227 and magnus 200gr 38 special bullets and my 4" 686 SSR. I wasn't thrilled with the results , not sure how much temperature played a factor (was 28 degrees today). Guess I will have to go to magnum cases. OAL was set at 1.50 but it varied alot probably due to using mixed brass and using the round nose seater stem in my dillon die (these bullets are round nose flatpoint)

700-725 FPS is the general velocity neighborhood that 200 grainers in 38 Special play within. That isn't world-class earth-shattering velocity, but compare the THUMP a 200 grain bullet makes at that speed with that made by a 150 grain on a steel plate in 38 S&W, and there is evidence that some property of inertia and motion is operating with the heavier slug that is decidedly diminished with the bullet weighing 75% as much. I'm sure as hell NOT ABOUT to stand downrange and try fielding these slow-movers with a baseball glove.
I went to 9.5 gr of 4227 under my Lyman bullet and achieved 822fps to get to 164 PF using 38spl cases in my Ruger GP-100. Recoil was relatively mild with no signs of excessive pressure. Lyman`s 45 Edition Reloading Handbook Maximum listed load.
John Goins published 4.5 gr Unique to get to 825fps using the same bullet.
I intend to work up a load to 800 fps for IDPA ESR using the bullet. Recoil should be relatively mild with good accuracy.
