Remington Model 600 6.5 Rem Magnum
I just found out I'm going to be 'gifted' a Model 600 Magum Carbine in 6.5 Rem Mag. It's been sitting in a gun case since 1971...unused. I don't know that a round has ever been fired from it. From what I've read here and other places online, in addition to factory ammunition being fairly difficult to find, the rifle also suffers from "punishing" recoil and muzzle blast.
I'm not a gunsmith, but it seems that the 600 would benefit greatly from either being ported or having a muzzle brake installed. Can anyone give me the benefit of their experience along those lines?
