Barrel Problem

[hereinaz]

I’d bore scope it to see exactly what the issue was but if you don’t have one, I’d read up on how to get carbon out of a throat and do that.

Yeah, cleaning the throat for carbon is usually the most efficient way to investigate/solve the problem. Sometimes the effort investigating is way more than just cleaning to see.

Use a good carbon solvent, those rings are stubborn.

^^Buy a borescope on Amazon and scrub the carbon ring out before you do anything else. I will be pretty surprised if you don't have a carbon ring. But def report back.

Sounds like it was a tight chamber to start with.

Update on this. Just took everything to the smith to get it borescoped and see if anything is going on. Definitely some carbon ring buildup but nothing was too crazy. He cleaned the barrel and then took a chamber cast. The cast showed everything to be to spec. The only thing that wasn’t checked was freebore or throat. Came back and chambered some rounds and there is maybe one very very slight scrape on the bullets but it’s honestly hard to tell.. I haven’t shot it yet so I will report back and see if I still have any pressure problems. I’m gonna probably be able to shoot tomorrow and see what happens.
