BSF Barrels 25 Caliber 20" 1:7.5 Twist Rifle Barrel

A 20" quarter bore barrel from BSF, twisted 1:7.5 and listed for bolt action rifles. One turn every seven and a half inches is aggressive for a .257 bore, and that much rotation is there for bullets that run long for their weight rather than short, light ones.

Twenty inches is a middle of the road length: more velocity than a short barrel, less weight than a long one. The chamber, the shank diameter and the muzzle thread are not listed. All three have to match your action, so confirm them before ordering.
