Like a lot of us on here probably did, I picked up the $49 teslong bore scope off amazon last week. Got it hooked up to my computer and started looking at all my rifles. It’s really interesting to actually get a clear picture of what’s going inside each barrel.
My initial inspection raised a couple questions for me:
1) how soon does firecracking begin on a barrel? My 308 with over 1,000 doesn’t show any whatsoever, just carbon buildup in the neck area. My 6.5-284 with 100 rounds on it has it, along with most of my other rifles even with under 300 rounds on them. Not scared of it; just curious.
2) is there a reason some rifling seems to have a very abrupt start to it and others seem very gradual? Almost worn looking. I got a 6mm creed with 150 rounds down the pipe off another member on here and it has the typical long freebore but then really smooth lands and grooves unlike some of my other rifles.
