.375 Lee Custom 6 cavity Boolit Mould

[Buckshot]

A drawing of the boolit is here:

http://castboolits.gunloads.com/showthread.php?t=4254

On post number 56.


1) Please understand one thing very well. The dimensions shown in the drawing are for the CAVITY ONLY and are NOT the boolit's "as cast" dimension in any particular alloy.

2) People new to casting should understand that a highly alloyed mix SHRINKS LESS and will produce a LARGER slug then one of pure lead (as a baseline).

3) Your casting tempurature will also have an affect on "as cast" diameter. The hotter the mould blocks, the greater their expansion potential. Bigger Boolits.

COST WILL BE $57 U.S. FEDERAL RESERVE BUCKS. I AM SHIPPING THESE WITH A DELIVERY CONFIRMATION WHICH COSTS $0.60. THE CONFIRMATION NUMBER WILL BE POSTED WITH THE PURCHASER'S ZIP UPON SHIPMENT. ALL WILL BE SHIPPED USPS EXPRESS MAIL.

DEPENDING UPON THE ULTIMATE NUMBER OF SUBSCRIBERS, I RESERVE THE RIGHT TO SHIP IN SEVERAL DROPS, RATHER THEN ONE BIG ONE. BRIBES FOR INCLUSION IN FIRST GROUP SHIPMENTS (SHOULD IT BE REQUIRED) GRATEFULLY RECIEVED

I sent you a PM, Ithink. I sure am glad to see this group buy happen. THANK YOU Buckshot.

[hpdrifter]

count me in, I'll pm later.

Just my opinion, delivery confirmation means diddly. I'd save my $0.60. They can throw it out the window and say they delivered.

[Urny]

PM is coming your way, Rick. Thanks for handling this.

[Buckshot]

count me in, I'll pm later.

Just my opinion, delivery confirmation means diddly. I'd save my $0.60. They can throw it out the window and say they delivered.

Hpdrifter, well it helps my own piece of mind. When I ran my heavy 8mm boolit a couple years ago I had ordered enough extra moulds for me to have a 2nd, and for 2 extra beyond the subscribed number. As per normal the zips were posted for the units as they were mailed in 2 batches.

I had a guy in Minnesota and one in Alaska e-mail who said they hadn't gotten theirs yet. I waited another 2 weeks and both said they never got there. I had to send the extra 2 I'd ordered.

Maybe I didn't HAVE to send them, but "I" did have to send them, if you know what I mean? With a delivery confirmation I do not have to feel any guilt or responsibility (missplaced or not) if one doesn't arrive. I'll feel bad, but I will have solid proof it was placed in the hands of the USPS.

With the postage increase, I probably should have made the subscription $58, but we'll let it ride.

Buckshot, you might check into registered mail. Very secure, and I can generall send things pretty darn cheap that way.

[Willbird]

Hey Buckshot,

Not sure if you have tried USPS click and ship, we have used it for all 3 buys we did, it works nicely, and you get free delivery confirmation in the deal.

Bill

[Buckshot]

...........Willbird, I'll have to check into that click and ship.

Depending upon how quickly the checks arrive, this group buy may end at the end of this month.

I'm not registered at Accurate Reloading, so if someone who is would kindly post a notice there I'd appreciate that. Before doing so, check to make sure one isn't already there 8).

The sooner we get our 25, the sooner the buy will go to Lee. Last minute situations may arise, but so far it's going smoothly. I'm not trying to set a record for most moulds on a group buy, so 25 is the target number. ZIPS are listed in the 1st post of THIS thread.

...............Buckshot

[Nrut]

Rick I have decided to buy another one of these molds but won't be able to buy the money order until the 17th due to work....Mic @ VOJ3AO......will post when MOD sent....

[475/480]

I will send a check today,I already have your address.

[4060MAY]

check went out today.

[Buckshot]

..............It appears that we should be able to close this group buy up at the end of the month with the check going to Lee the 1st week of April. We have 13 checks for 19 moulds, 2 more on this thread said they had sent checks and I just sent my addy out over 3 PMs.

Maybe we can get this all wrapped up very quietly and have the distinction of the group buy with the least number of thread hits 8)

Buckshot-

My check for 1 mould went out in todays mail. Zip is 48415. Thanks for running this group buy.

[45 2.1]

Buckshot-
BEFORE you send this drawing in, please clear up the gas check shank dimensions and notes. It says the dimensions are cavity dimensions and the shank is dimensioned, it also says cut the shank for the Hornady check. It would be less confusing to them to put the "Cut shank for the Hornady check" at the location of the dimensions with no dimensions given. Your choice, but get it right please. I was one of the plain base guys and don't want gas check fit problems.

[Buckshot]

.............This will be the last week the group buy for this design will be open, Officially :-). I will 'Un-Sticky the thread and let it float down the list. All last minute checks will be recieved hopefully this week.

The design by Tom and the money will be mailed off to the happy workers at Lee on Monday April the 3rd. I may or may not order a few extra moulds, but I wouldn't count on it if you're hanging fire.

The END IS NEAR!

Hi Buckshot,

Sorry I'm so late....

Check is in the mail 3/31/06.

Thanks,

BlueSmoke

[Buckshot]

...............Due to late checks, I will hold off mailing the group buy to Lee until 4-7. Any checks recieved after that date will be torn up, burned, folded stapled and mutilated. Any of those will have thier zips posted so you'll know what happened to them.

Technicly the group buy is over, so I will unsticky this thread and allow it to float down the list out of the active sticky area.

All zips recieved as off 4-1 are listed in the first post of this buy.

..................Buckshot

[Buckshot]

..............The envelope to Lee is addressed and sealed. Will be posted today 4-17-06. Hopefully we'll see the moulds mid-June.

Thanks to all the subscribers, and to those who included a few extra bucks. Muchly appreciated!

[garandsrus]

If anyone has a mould that they don't need, please let me know! My timing is not good as I just got a .375 and missed the group buy.

Thanks,

[Buckshot]

.................To any who might be slightly interested, Lee says the moulds will be run next week and most likely shipped the following week.

.............Buckshot

[Buckshot]

................Moulds arrived. I pulled one out and cast some 21 BHN alloy in a quick and dirty test. It's 104 here today (cooled off a bit) so it didn't take too long for the pot to heat.

Slugs are dropping at about .385" so any fears of being too small can be put to rest :-) I suppose WW alloy will see them around .383" or so and pure lead about .3815-.382" I'd imagine.

The 3 crimp grooves cast very sharp and clean. Even the first few imperfect based slugs were looking good on the nose and drive bands. I was in a hurry so flushed the cavities with carb cleaner, smoked lightly, lubed abd began pouring. If they all work like this I don't see any issues.

I'll ship Thurs-Fri so you will see them next week.

Buckshot

[Dutch4122]

That's great news! Thanks for updating us on the test cast and thanks for all your efforts on behalf of the group.

I'll be watching the mail.......

[Frank46]

Buckshot, what great news!!!!!!!!!. Now I have absolutely no excuse whatsoever for now casting up a bunch for my 375 win big bore. Will be watching the mail like a hawk. Methinks that going with fatter dimensions may well prove to be a blessing in disguise as it will enable the boolit to fit a wide variety of 375 rifles. Thanks for honcho'ing this group buy, Frank

[Buckshot]

............All moulds going to addresses in the USA were shipped today.

I need 40324, Nelson to PM me as regards your sizer.

Moulds going to Canada will ship Monday. The only reason they did not ship with the rest is that the computer "Click and Ship" program recommended a stick on declaration lable I did not have and which I picked up at the PO today. Plus I picked upome International Priority envelopes for the boxes.

This buy turned out very well by specing the dimensions for the CAVITY to be cut at vs the desired OD for the boolit. Lee guarentees -.000 to + .003", and our print showed a .384" cavity. As mentioned the 21 bhn slugs I cast were AT LEAST .384".

I just went out and tried a Hornady GC and it was a snug fit, but DID 'snap', on a few I picked out and a couple times it was snugger.

Any of you guys that ordered these having a FAT 38-55, 375 Win or whatever, this slug should do the trick :-)!

Hi Buckshot,
My mold arrived today and it looks great. My gas checks arrived last week and as soon as this humidity lets up a little I'm gonna fire up the pot and cast a bunch of these for my Marlin 375. Thanks for all of your work to make this buy a success.
Regards,
BorderBrewer

[lar45]

Very cool. I can hardly wait. I have a Win 375 BB, and I also picked up an extra 375 win barrel at Nuemrich. I picked up an old M94 30-30 and was thinking about putting the 375 barrel on it. I'll just have to keep the loads at 30-30 pressure.

Thanks for doing the work on this.

[Steelbanger]

My mould just arrived. Wouldn't you know that the temps are supposed to be in the mid 90's for the next few days. I'd like to shoot some of these with gas checks before deciding whether or not to change this to a plain base.

Thanks for running the show Buckshot. Your efforts are much appreciated.

[4060MAY]

Mold arrived today, looks good. Too hot to cast. will post how it shoots after it cools off a bit.
Thanks for the Honcho.

Buckshot;

Just got back from the mailbox. The mold was there. HOT DOG.

Speaking of HOT - it is 93 degrees here and about 115 degrees in my casting room, but I'm a gonna go in there and do it anyway. If I survive, a report will be forthcoming.

Thanks again Buckshot - You da man.

Tom Myers

[Dutch4122]

Just picked mine up at the mailbox. Zip is 48415. Everything looks good. Too hot to cast here as well. The Humidity is just darn oppressive. Thanks to the Honcho & designer for seeing this one through.

[Johnch]

It arived today , 43445 :drinks: :drinks:
Thanks for running the group buy Buckshot

It is 95 so I will have to wait a little to cast any .
Besides I have to decide what to buy to use this bullet in .

Thinking either a 375 Win or 375 JDJ Contender barrel .

Johnch

[C1PNR]

The package arrived safe and sound today at zip 83706. Thank you very much for running this buy.

I think your idea of specifying the cut dimensions, rather than "as cast from mystery metal," is the way to go with orders from Lee.

Thanks again, and let me know when you want to run the 7mm "Buckshot" design. I can hardly wait![smilie=1:

[Tom Myers]

Well, I survived the heat in the casting room. Didn't have to be in there long. It only took about 30 minutes to cast up about 120 absolutely fantastic bullets.

My 1/20 Tin/Lead alloy cast at 0.384" on the bands and 0.372" on the bore ride portion and the bullets weigh in at 255-grains +,- 0.2-gr.

All linear measurements are very close to the original spec sheet as indicated on the sketch below which shows the actual dimensions of the castings.

The only problem is that the gas check shank is a tad large. I need to lightly flare the checks to get them started. Maybe annealing them will eliminate the need for flaring.

Perhaps next time we might want to leave the cut to specifications for the gas check on the drawing. Whadaya think?

All in all I am very pleased with the castings from this mold. Now, if it will just shoot like I think it will, I will be one happy shooter.

Posted is the spec sheet for the actual casting dimensions and also a couple of pics of the bullets.

[chromecrow]

40391 arrived safe and sound. Thank you Buckshot.

[45 2.1]

I got mine yesterday. Since this is the first buy involving a mold cut to a certain cavity dimension, it would help to get some data from this so other mold buys could benefit possibly. Someone with the equipment needs to measure the actual "cold" (that is room temperature) internal mold dimensions; nose diameter, band diameter etc. Then various alloys should be cast and the "one day later dimensions" involving air cooled and water dropped could be reported. That would give us a basis for dimensioning future buys if using this method. This won't happen unless we all try this.

[bdoyle]

When I did the SCII GB I had to provide a new drawing when I had the moulds recut. They (lee) ran the given bullet dimensions as mould dimensions. I took the undersize mould and cast some WW. I later cast 'bullets' with cerrasafe ( the stuff from brownells for chamber casting). Using the two diameters I came up with a scale factor to properly dimension the new drawing. I used boiling water to melt the cerasafe but it will melt as low as 140 degrees. The rerun did cast bullets to the original spec. I did post my scale factor but I don't have it on hand right now.

[trk]

Threw a few this evening (90 dF where I cast).

800 dF

Mostly lead, a little 95% tin solder.

Cast to 260 grains and .385" in diameter.

Next is the important thing - to see how they shoot.

Good lookin' bullet!

[KYCaster]

I took a look at this mold for the first time last night and wasn't too happy with the way it looks. Decided to let it sit a while before I got too PO'd. Took another look today and the more I look, the less I like it.

All the other six cav. Lee molds I have look like the final cut on the top of the blocks was done with a lathe, leaving a radial pattern of tiny grooves centered on one of the cavaties. This one looks like it was hand honed on a surface plate with 400 grit paper. One of the mold halves has almost all of the lathe cut removed, but the other block still has the radial pattern visible on about forty percent of the surface adjacent to the parting line. It appears to me that the blocks were not held in proper alignment as they were being sanded.

When the blocks are placed lightly together so the alignment pins will mate like they should, the tops of the blocks don't line up perfectly. One block is about .002 or so higher than the other. I know that doesn't sound like much but with a little bit of pressure, I can get them to line up right. But pressure in the other direction will make the mismatch about .006, and I think that's enough to cause some problems.

It makes me wonder how well the cavities match. I guess the only way to find out is to cast some boolits with it, but I'm very tempted to send it back to Lee and ask them to replace it.

Has anyone else noticed any problems with this run of molds?

Jerry

[lar45]

Got my mold, thanks. I like the way the boolits look. Hopefully I'll be able to find some time to load and shoot some in my Win 375 BB.

I scrubbed with hot soap and water with a tooth brush, then colored the top of the mold and underside of the sprue plate with a pencil, then smoked the cavities with a lighter.
I heated up the pot and cast about 100 or so. I measured around 20 for dimensions and weighed them also, but CRS kicked in and i forgot to post it and now can't find the paper.
I did notice that I had to have the pot turned all the way up and the mold very hot to get the tripple crimp grooves to fill out all the way. I tried casting another mold at the same time and the crimp grooves started to get rounded edges on them. I went back to just the one mold and they started comeing out nice and crisp. I also had to keep a big puddle on the sprue while casting.

I'll dig around and see if I can find my notes.

[lar45]

Found my notes. My mold is dropping WW boolits at .384-5" and 254gns.
My gas checks push on the base and stay there.
I'm happy,
thanks.

[Frank46]

Buckshot AND Tom Meyers thanks for making this group buy possible, too darn hot to cast at this time. Frank

[garandsrus]

I had a chance to shoot some of these this evening in a .375 Win 94 Big Bore. They shot great! After getting sighted in, the group was about 1 1/2" at 50 yards (peep sight) off a bench. The alloy was ACWW sized to .377 and the rifle showed no leading at all. The powder charges were 7.5 and 8.0 gr Red Dot. I loaded the .375 to .38-55 levels.

The 8 gr had a little better group, but both were good. Now that I know that the bullets and the rifle shoot well I can work up a load that might be even more accurate. I didn't chronograph the loads.

I was very happy as I had purchased some commercial cast bullets while waiting for this mold and they leaded the bore. They were plain base, by the way. I couldn't keep the shots on the target! I was wondering if the rifle (new to me) had a problem in the accuracy department. Now I know it doesn't!

John

[hpdrifter]

finally got to pour some lead into mine. Mine came out .381 with ww+.02 tin. Cast kinda hot tho. Maybe with fine tuning of the heat, they'll "grow" a tad. Need to Leement them a bit also, they's dropping out kinda hard.

I appreciate the honcho's efforts immensely. I know it must be kinda involved. Some people are cut out for it and others(meself) prolly aren't. Thanks for all the effort and time!!!!

[edit]Forgot to add, I think I'm gonna like the six banger casting; sure put outta bunch o' bullets pronto.

[3584ELK]

Thanks for being the Honcho on this group buy, Buckshot. It looked exhausting and I really appreciate your work, sir.

I will clean up my mould and see what it casts. I like the 6 banger design.

[Steelbanger]

Had to try this mould so I cast some a few weeks ago. I started early in the morning before it hit 90º. Didn't spend too much time preparing, just cleaned the blocks with lighter fluid, lubed the alignment pins, pivots and let 'er rip. My alloy is very hard since I have more type metal than anything else so my bullets are a bit light, weighing about 250 gr. with lube & gas check. Sizing to .379 almost closes up the crimp grooves but they aren't too large to begin with.

I shoot two different loads in my 38-55 Marlin Cowboy - Unique with the Lee bevel base 250 grainer (Chickens & Pigs) and 3031 with a Rapine 260 gr. GC bullet (Turkeys & Rams). So, with this new bullet, my thought is to simplify my loading by using the one bullet for everything but still loading it light for the closer targets.

Using a receiver rear sight & globe front, the first group with this new bullet and Unique went into a round 1.25" @ 50 yds. with the second group just a bit larger at 1.5". Going to my 3031 load the first group went 1 5/16" and the second 1.75", these at 50 yds. also. My eyes aren't getting any younger so these numbers are completely satisfactory to me. And these groups are on a par with my standard silhouette loads, which is what I was after.

Thanks again Buckshot for running this group buy. It was worth the wait!

[garandsrus]

Steelbanger,

Are you going to shoot the light loads with or without the gas checks? Have you tried it yet?

Thanks,
John

[Steelbanger]

garandsrus,

Only shot it with the GC. I guess I should consider trying without because of the increased price of gas checks.

My only experience when not using a gas check on a gc bullet was a long time ago. I tried a heavy bullet in a .458 Win, wasn't on paper at 100 yds and when I moved to 25 yds. it went through the target sideways! That was my only experience of not using a gas check. Probably 30 years ago and I can still see that outline of a sideways bullet.

[dltaskey]

Finally got casting with this mold yesterday. Mine must have been cut last since the boolits drop at .387-.388. Sizing to .379 pretty much eliminates the crimp grooves! I have to use a mallet to seat the gas checks. I'm using WW and .02 tin.
Would casting really hot have any appreciable effect on size or would changing alloy a bit shrink the varmints?

[DEVERS454]

Well, using Lyman #2 alloy and the heat all the way up, my bullets are dropping from a graphite sprayed mold at .383" weighing in at .247gr.

A very nice mold. I had to use a small peice of round brass and go around the permiter of the cavities to get rid of some burs.

Otherwise, thanks!!!

UPDATE: Trying to resize these is a major B!TCH of a task... yikes...

I may have to use a .379" die instead of my .377", just so that I can get them down.

That .008" difference is more than my puny lee hand press can handle. Even my turret has more fun than I care to give it with this.

[Last Spike]

I'm wondering if there are any extra moulds available.

For some inexplicable reason, I wound up buying an excellent 1894 Winchester in 38-55 made in 1920 that mikes .379 groove diameter yesterday.

So there you have it - I need to feed this pig.

[Buckshot]

.............To reduce the OD you can spray the cavities with something like Midway's mould drop out. You'll loose a couple thou that way.

Best way would be to Tumble lube and then shoot them up through an intermediate die. Also find out the max OD your rifle will handle leaving a bit of room for casemouth release.

BTW, what kind of nose punch for an RCBS Lubrisizer are you guys using with this mould?

Thanks,

Keith

eka,

Top punch for this GB .375- I tried several, and the one that works best for me w/o scoring the nose is RCBS #607.

I finally got to cast some up last night,they cast at .384-385.The gas checks fit good and snug.They did fall out of the mould fairly easy.
I hope I can size down to .377 with no problem.

............You might want to go through a .380" push through first.

I got to shoot the 375-260 GB Mould this weekend.
TC Encore 375 GNR (445 SM necked down to 375)- 10" Bll,using a TC 2.5x7 Scope.
WC 680-29.0-30.0 gr 1600-1675 fps -1" at 50 yards.This is pushing 50K in the Encore.
These were water dropped WW w/FWFL hand lubed.The as cast is .384-.385 so when I size down to .376 the bottom 2 crimp grooves are ruined,but it works out pretty good in the end.
