Hello folks,
I'm far from a gunsmith. I'm just a guy that like to shoot and reload, so I was hoping to lean on some of the vast experience of this forum.
A buddy gave me an old hunting rifle to work on his reloads for him. He had been running the same load for years but it suddenly stopped shooting good. Also the velocity went through the roof. He thought maybe powder lot or bullet lot changes might have been the problem. I shot it a little bit with some very light loads (according to the book) and pressure was bad right from the start. I did a light cleaning on the rifle (patches only no brushing) and thought maybe I'd try out my cheap Amazon endoscope to see if I could see anything.
I know the pictures are low quality but is it enough to determine the issue? I'm seeing a black ring in the throat area, is that the dreaded carbon ring? Could that be what's causing the pressure spikes?
I'm also curious about the black streaks on the lands, is that fire cracking? Any help interpreting these (admittedly low quality) picture would be appreciated.
Thanks in advance.
