I dont know what forum this would go in, so im putting it in this one since it gets a lot of traffic. I bought a fire lapping kit from beartooth bullets for my S&W 629 44 mag. Ive put about 30 rounds through it so far, most of them got stuck in the barrel and i had to knock the bullet back out with a dowel rod. Ive cleaned the barrel a littled and looked down it with a light, and its already like looking at a mirror in there. But there is one area down by where the threads would be for the barrel where i can see small grooves or scratches running a short ways along the valleys in the rifling. At first i thought it was leading, but that isnt possible. Its defiantly in the rifling. Is this typical? Or is it something to be concerned about? I know there was a constriction around in that area. I havent been able to get any more sinkers to test it out again. But i was shooting jacketed bullets, i wonder if that is where the scratches came from. So i guess my question is, should i keep going these scratches or grooves are gone? Thanks guys
