So I'm curious about barrel bulges. I've never knowingly seen a bulged barrel, but I've read online about them. This has me wondering about them. What do you look for when looking for one? I'm just afraid that if I ever buy a used one, I need to know how to check it as I don't want to buy one with a bulged barrel. Anyway, is it something that is major on the outside? Or is it something that may be very hard to see at times? Should you be able to see it on the inside looking down the bore, or is it normally only visible on the outside? What's the best way to make sure a barrel is not bulged before buying a gun? It also seems that some guns I've seen the barrels are not perfectly 100% smooth on the outside although they are usually very very hard to see a difference, but I've seen some in the light where you can see differences. So how do you know if it's just that or a bulge?
