really cool stuff. this means many pistols can now be used and sold and enjoyed! well done.
now, I wonder if it would be just as easy to convert them to 7.62x25?
a couple of pistols already in this caliber, and one is a very recent thing.
you are already using .30 caliber barrels, and a bottleneck pistol cartridge.
just thinking out loud. Cheaper ammo, readily availiable, load data widely published, components availiable as well.
