Lizard has a ton of 22BRs and he just finished a 6BR. Give his ear a bend about it. I think he has a Lapua brass reamer. I think a 6BR would feed from a 308 mag. Might want to look around at http://www.6mmbr.com/index.html Barrel life should be close to 2500-3000 with mid range bullets.

Any of three are good choices. For a short barrel plinker, the 6BR would be the best, but with really expensive brass...
