BSF Barrels 25 Caliber 22" 1:7.5 Twist Rifle Barrel

Twenty two inches of 25 caliber bore with a 1:7.5 twist, listed for bolt action rifles. The twist number is the distance a bullet covers for one complete rotation, so a smaller number means more spin. At 1:7.5 this one spins hard, which is what long, heavy quarter bore projectiles need to stay pointed.

Length buys velocity and costs weight, and 22" lands between the two. What the listing does not include is the chamber, the shank diameter or the muzzle thread - confirm those against your receiver before ordering.
