I realize that a Mauser isn't as desireable as some higher dollar action, but that being said, I have built several sub-moa Mausers in the past. Amazing things, those lathes! Don't start the whole MPI thing again. Nuff said.

Swampman, I am making a Ti firing pin and going to try some different springs to take care of lock time. Good point though.

More on the cartridge, I have no experience with the 243 AI. Has anyone busted whitetail sized game 400-500 with it?
