I believe it's a 1 in 12" Twist .. I'm kinda new to Centerfire Rifles.. Growing up in southeastern, Ohio A good 12Ga and a 22 Long rifle will do just about everything You want For hunting Needs... I thought the 223 would be a good Yot and groundhog Rifle.. Plus Cheap to shoot from what I've seen on Ammo Prices.kb said:What is the rate of twist of the 223 barrel? Im thinking of getting one to play with.
