Yeah-h-h, but how do you have enough neck for a lube cookie right?
Well, I've been pouring over the books trying to come up with a cartridge to put in an old 1800's bolt action. And while I was at it the brain spun off into wildcat wonderland and the 7.62x39 dimensions distracted me for a while.
So, what if a 7.62x39 die was shortened on the bottom end to full length resize something like a 30-30 to make a straight case with a fat hind side.
No way this would work for the project at hand but I'm gonna file it away in the possibles bag for that gun show find waiting over the horizon.
