Agreed. When i commented that my Savage was "oddball" i was referring to the very slow twist. I should have better worded my post. My 24" Bushmaster Varmint AR is a 1-9 which is better for 69's (still borderline for 77's ) . My White Oak barreled service rifle is 1-8" very good for 69-80's.That twist rate is too slow for heavier projectIles. Probably made for varmint shooting with lighter projectiles at high fps.
I shoot 80's for match shooting at 600 yards and that's pretty common. Most match .223 rifles are faster twist for the heavier projectiles.
