Found a Montana 223,non threaded barrel. Anyone know twist rate? Rifle is new. Had a 7-08 once and it would not shoot. Any better now?
I've had something like 17 MT's now, and while some are finicky, with a little patience and experimentation all of them shot something sub moa.
I mostly don't buy the "would not shoot" idea... what that often means is, "it wouldn't shoot what I wanted it to shoot"... or just as often the operator can't shoot a light rifle.
