Hey guys.. I just got a new inline from my uncle. It's never been shot. What should i do prior to shooting it the 1st time? I'd guess a real good cleaning since it was absolutly soaking in oil from factory. Also its a percussion cap #11 and the manual i found online say nothing about using pellets instead of using loose powder. Anyboy that could help me to insure i'm not using somthing i shouldn't would be greatly appericiated! Its a century arms centurion 50 cal. Also what all will i need to start shooting it? i've never ever shot a ml before if that helps?!?
