Hey,
I've got a 270 Xbolt that used to be an incredible shooter... shot multiple 5 shot groups in the .4s. However, the group sizes have since opened up over 1" and I've been scratching my head trying to figure out why. I did all the normal stuff, checking scope, rings, action screws, brass, even trying to re-work the load. I recently bought a bore scope so I could take a look at the barrel of this gun and my other rifles. I compared the barrel of my 270 to several other guns and found some things in this barrel that I didn't find in any other gun. I'll post pics below.
Pic 1 looks to be some kind of fouling, but I don't know. I've used multiple different types of cleaners (foams, Butch's, Boretech Cu2, etc) with both patches and bronze brush. This evening I switched to Losso and the patches are coming out black, black.
Pic 2 seems to show some kind of scarring/pitting???
Pic 3 this is toward the very end of the barrel (muzzle). I have no idea what this is.
Can anyone help me interpret these photos and advise me on steps I should take moving forward? Thank you in advance.
