No need to try and save your barrel, that's what gunsmiths are for.
I would have thought it would be Niles Viking instead of coyote.....

[Beluebow]

140 grain vlds, H4350 COl 2.840

I know every rifle is different but that seems kinda mild to be flattening primers.No ejector swipes or sticky bolt lift? Are you jammed at 2.840?

 

[704]

not jamed until 2.847
bolt was tight on one shell during extraction, so yes sticky bolt

 

[704]

finally found the load
