Questions & Answers
Will this work for 308 or 300BO or only 300mag?

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).
