It will work for any caliber UP TO 300Rem Mag…so any bullet that is .30 cal or smaller, including 7.52x54, .208, 30-06, 300BO, 7.62x39, etc. Of course, make sure the threads on your barrel are 5/8x24. You could even use this for .223 if you use a threaded bushing to change the threads to 1/2x28 in order to pin and weld on a 14.5” barrel to make it just over 16” (think about it).
