Custom .625 dia?

[Blammer]

Who can produce a custom .625 dia bullet mold? Seems most stop at .50

any suggestions?

[Catshooter]

NEI. IIRC, they have a 4 bore in the selection.

Dan at mountain molds will.
I punched in the numbers and I got a 1085 grain bullet .

B&D has recently cut a cherry @.592 so .625 should be no problem for them.

Blammer,

I'm looking for a .625 mold myself. What did you have in mind?

What are bou guys using these molds for? What caliber is it?
A 20 gauge from hell?

A 20 gauge from hell?

That's my plan.

Believe you can get a .625 round ball mold from Dixie GW, for about $20.00 via mail order... chkitout. Couple of years ago I got one at .80 cal for a sling experiment..

Heck, Greg, a .625, is just a slightly chubby 20 guage. You need to get up to around .750 for a 12 bore!

Take a cheap Lee mold like the 515-500-F. Drill it out to 19/32", then run a 11/16-11 bottoming tap into it. Size to 0.625".

A 0.625" round ball will only just touch the grooves and over a very small area, leaving lots of gaps for gas-cutting. A 0.635" ball, is about what you need.

[Greg5278]

Myabe I'm way wrong, but I'd stick with a 600 grain Truncated cone bullet. That should keep the pressure low enough, and the velocity high. A heavier bullet could be used but then it wouold be like a .600NE.

My concern isn't really the mold. Lee will do the mold as will Mountain Molds.

My concerns are designing a bullet to avoiding shrinkage problems and finding a sizing die.


David

[Greg5278]

Molds should not be a problem, the larger calibers require larger block with shallow handle slots. That is why nobody wants to fool with them. I made my own blocks for 12 gauge molds. The biggest bullet so far is an 871 grain truncated cone 12 gauge bullet.

You can have a custom sizing die made to fit a relaoding press. I removed the threaded bushing from the press, and had the die made to fit it. For a 20 gauge you might still be able to use the 7/8"-14 size. I think unhardened blanks are available.

There doesn't seem to be much interest in homemade stuff in this forum, but for those so inclined, making a 0.625" sizer couldn't be easier:

- take some 1 1/4 - 12 threaded rod (or the threaded part of a bolt) and drill it out to 5/8" That's it. If not smooth enough for you, drill a bit undersize and then fnish with a 5/8" reamer instead.

IMO, 7/8"-14 will be too thin for anything over about 0.500".

What a brilliant, simple answer for large diameter boolit moulds. Drill the hole and ream to finish size, the just use a coarse thread tap for the grease grooves.

Wow!!!

only1- I am looking at a full bore 20 ga slug for my 20 ga shotgun, rifled brl of course.

I was thinking a hollow base and somewhat of a pointy nose with maybe 3 bands to engage rifling.

Looking at hollow base and hollow nose to reduce wt, not so much for aerodynamics.

when they get that big they get heavy.

was hoping for something more aerodynamic than a RB or a wadcutter looking thing.

The "minie" design of the civil war era with a thicker base may be an option to consider.

also, possibly .575 dia would be good, as you could use existing standard 7/8 oz shotshell wads as a 'sabot' of sorts. but the weak point in any shotgun sabot is the standard shot wad...

I' was hoping to keep the wt around 1 oz at the most, which is up to about 460 grains...

[Blammer]

as far as a sizing die goes, if you put some 'bands' on the bullet you can have them 'engage' the rifling with out really worrying about sizing too much....

or if you use the minie concept of slightly undersized and use a "skirt" to grab the rifling with obturation, the bullet could then be bore riding or slightly engraving.

the lyman sabot slug, is a fairly good idea, it just needs to be more aerodynamic. Put a Trun cone nose on it, shorten the space from the top band to the bottom band, bla bla bla...

the problem is that mountain molds doesn't do hollow points or hollow bases and they can only cut the "grease" grooves soo deep.

I don't know about lee...

[Blammer]

in addition to looking into getting a full bore slug for my 20 ga.

I am looking for some 58 cal minie bullets in the 300-500 range that I can test with my sabot in my 20 ga.

[Hackleback]

Two fingers and I were discussing threading a lee 12 ga slug mould to make a full bore slug. It the time I thought I was way out on left field and was not even going to say anything about it in here. But....... it appears that great minds think a- like!

[Idaho Sharpshooter]

the envelope please....and the answer is (drum roll) the Lyman Sabot Shocker mould in 20 gauge!! It is designed for shooting in the 20 gauge and looks just like an overgrown air rifle pellet. Wasp waisted, hollow base, rounded nose. The coolest thing about them... mine is a 12 gauge that weighs exactly 530gr ( 1 1/8oz) so I could start loading with 12 gauge trap load data and work my way up. Use a shot cup and go happy with skeet loads for starting data. I have a Savage 210 fully rifled barrel boltgun in 12gauge and I am getting sub-2" groups at 100 yards at 1760fps. That beats the 45-70 with that weight bullet, and out of pure lead they hit like Thor's Hammer. I had to name the rifle/shotgun Mjolnir!
