Forming 243's

[Ray Z]

I've been trying to find once fired 243 Win brass without much luck. I read that it was formed from 308/30-06 brass, so I tried running some of the 308 that I've got coming out of my ears through the 243 resize die. It looks good and when I measured the dimensions that I got from Siearra's  manual and they are all a bit under. Has anyone done this before? Do I still need to get an outside neck turning tool? Fire form?

I used to form 243's from .308 and I don't remember having to turn the necks. Probably should have, but was mostly just trying to see if it worked. It shot fine with cast boolits.

How much brass are you needing?

Thanks for the help

I need at least another 300 pieces. I'd like to see if this will work. I've got a lot of 308 once fired brass. If it doesn't, I'll get back with you.

Thanks

I can give you some brass, too.  Not 300 rounds, but a few.  Next time I get down there I'll count up what I have.

 

I've formed a lot of brass.  It's a good skill to have.  Very necessary if you can't get factory brass.  But if you can get factory brass, forming is more a PITA than it needs to be.
