Hello guys, its me again looking down the barrel with my flash light, this time its new rifle I got as a replacement for the one I complain before, everything is shiny as a mirror for the exception of one spot at 2 o'clock its right one the riffling about 3/8" from the muzzle, when I pass it with toothpick I feel its not smooth, it feels like a pit, or piece of riffling missing and it looks like its fresh. Can bullet passing through break piece of riffling? Anyway I feel like I'm having very special luck lately. And my question is" how critical pits like the one I found neat the muzzle and can they critically effect accuracy. During my test at the range today, I had 2 fliers out every 5 shot group, but they were within 1 MOA. The test target my rifle came with had almost the same 2 shots same hole and a flier which made it 0.91" group.
