Need some input from your more experienced shooters.

Had an issue where I couldn’t close the bolt on factory 108 ELDM after my first box. Ben at PVA suggested I likely had a carbon ring and to clean that out. Seems awfully quick but I’m no expert.

I bought a bore scope and here are photos before & after cleaning.

There is clearly something at the free-bore area that is either a carbon ring or a bad edge on the throat? I have an untrained eye.

The after photos has me perplexed why there is now a longer flame looking metal?? Definitely chambers better but not butter smooth.

Thoughts?

Looks like it was shaving copper off some jackets at the start of the freebore? That would align with what @bojangles808 was seeing on the bullets with his in the other PVA 6 creed thread.

The "Flame" just looks to be the difference of where you got the carbon cleaned off and down to bare metal in one spot.
