More bore scope help, please - 03/25/24
Working on another “problem child” rifle. A CLR/NULA that has not been as precise as I anticipated. Decided to bore scope it and have a few questions.
Pic #1
Is this hard carbon fouling?
Pic #2
Tooling marks just beyond the leade. How big of a problem is this defect?
Pics #3 -
Found these radial grooves throughout the bore. They tend to be deeper or more prominent near the chamber and less near the muzzle. How much of a problem are these and what caused them?
So, what are these defects and what impact would they have on precision? Any input would be helpful.
I’ve have other avenues to troubleshoot with the rifle, so am not set that the barrel is only problem.
Thanks
Scott
