Good question. I'm not 100% sure but if I remember corectly the 221 case has a rim on it like a 30-30. If that's the case you don't need to sit the bullets all the way out to the lands because the headspaceing is done at the rear of the shell regardless of where the shoulder is. If the case is of rimless configureation you could probably get enough of a shoulder at the base of the neck when you size your brass down. Just leave your sizeing die backed out a bit and size the neck back a little at a time, trying the sized brass in your rifle between die adjustments, until the bolt will close with a very small amount of resistance againced the rear end of the cartridge. As far as powder charges go, If the case is being reshaped like an Akley improved cartridge where the shoulder angle and body taper are being blown out, then it is ok to use a stiff charge of powder because the extra room in the chamber will lower the pressure. If the case is a basic neck-down job like 30-06 to 25-06, then I'd say to use the lighter powder charges or forget about the fire forming and go straight to load development.
My guns are mine, they aren't for sale, and I only give guns to people that I really like. So I guess the government is **** out of luck.
