My son got himself a 50 cal inline rifle and has been gathering info. He came to me today and was asking if I had any 50 cal hollow base bullets so he could fire lap the barrel. From what he has been reading online if he fire laps the barrel it will smooth it out and would help in two ways. First it will making cleaning the gun easier and faster since the barrel will be smoother and also aid in how the rifle shoots.
I do not think firelapping a barrel right out of the box is a good thing but I am not a expert. The only time I would do it if I had a barrel that needed cleaning up and it was not shooting very well at that point what do I have to lose. Any advice on this would help. And if there is anything you do to a BP rifle to break it in ?
