i am looking at buying one of these for a project. my concern is firing pin dia. they have a .067..not a .062...but not big either.
so if using a 0.473 case head with a small primer and building for accuracy, what say you on the .067 firing pin ?? get it rebushed to .062. use as is or skip the macbro action. thanks

0.062, 0.068 or 0.070 will be absolutely fine
It is more about the fit of the pin

Michael, I've had both the EVO and EVO II Mack Bros. actions and have measured and investigated them thoroughly. This one is done up as a 22 Creedmoor twisted 1:14. It shoots the BIB 52's into nice little groups at 3,860 fps.
