I bet the Eye-talian's 1-48 tooling wore out and some schmuk said "Hey why not use the same 1-60 like the...". Surely they didn't calculate the lessened wear from lesser twist. They's a formula "out there" somewhere that calc's twist for grain wt., velocity etc. Modern barrels err on the side of tighter twist, just don't twist so tignt as to overstabilize the pro-jec-tile. I ain't sure what overstabilized is and can remember when I could shoot not quite as well as you younger fellows? I'm very impressed!! :hatsoff:
