Folks are Berry's bullets suitable for breaking in a new bore to get it ready for cast? I have never used plated bullets for this task and i was thinking of ordering a thousand jacketed bullets to break in a new bore and i thought if plated bullets would work i would give them a try. I am not talking about a rough bore mind you...just a new bore. Before someone suggest it i will go ahead and say that i do know about polishing the bore and have done it in the past, but i would rather be shooting.
