Reforming Brass for another caliber

[woodstock]

Just started reforming 30 06 brass into 8mm mauser because 8mm is most often berdan primed and what isn't is $$.

Found some once fired 30 06 at the last show I was at, about .47 per case all of it RP.
Decided to anneal it with a torch as the case has to shrink slightly and the shoulder moves down from the 30 06 location.

Lots of lube on this and gently pulling the handle results in a case with an elongated neck that has started to shrink to 8x57 dimensions.

Then I cut the excess length on the case to max length and resize it so the neck and shoulder are good and then recheck dimensions.

It's a common practice for me. I've recently loaded 7X57 using .257 Bob brass. I never thought I'd be doing that!

7-08 to .308, 30-06 to 25-06, etc. Brass is incredibly malleable and forgiving.

.223 to 300 blk is enough for this guy. Lol

I have several file trim dies for this--8mm , 7mm, 7.65 Arg, from 30-06 as well as 7.62x25 from 5.56 brass. or 9mm mak from 9mm luger.

I do 5.56 to .300blk and a wildcat in .264 all from
Lake city 5.56 brass

3 calibers from the same brass, powder, and primer.

I set myself up a series of rifles based on the.308 cartridge. With the 308 parent being commonly available, I now reload 308,243,7mm-08, 260,338 Fed. Works great and on the cheap.

I reform 223 to .300 aac as well. Also have formed some .243 into .308 for my light plinkers. Dont get too many firings out of em before you get a neck split but what else does one do with .243 brass? lol

Almost everything I shoot in my contenders is reformed from something.

One thing that I have done is buy a mini-chop saw from Harbor Freight. Then I drill a hole in a block of oak to the depth of the final case length +0.020". Just drop the case in the block, chop it off and then do another. Then trim to final size.

try annealing your cases either before or After you run them into the 308 die.
