I was speaking with a gunsmith that I very much respect today and asked him if he slugs barrels before he chambers them. His reply was that he found it unnecessary for centerfire rifles which surprised me. I adopted the practice several years ago because I was having accuracy issues with a couple of rifles and found that when I slugged them the muzzle end was .0015" larger on one and .002" larger on the other than at the chamber. This was before bore scopes were readily available but I could not detect any other defects in these barrels.
So I am curious now. I know several here have more experience with this than I do so I just wondered. Is this a normal practice for you or am I wasting my time?
Thanks for looking.
