thoughts on this chamber

[Borisserge]

A friend brought over his rifle to have a quick look over.
A look down the tube and this was the first thing we saw.

This is 6x47L with just under 800 rounds through it with 105 hybrid and 38.8gr H4350

The rest of the barrel doesn't show up on having fire cracking that would match what we see here.

Is the neck of reamer been too long?

Thoughts guys?

The neck of the reamer is not too long that just shows that the room left from the end of your brass when you trim your brass everything looks fine to me although I might use some JB bore bright before you get much more carbon built up

He needs a bronze brush to stay on top of that once he removes it by other carbon reducing methods like jb or iosso and a bit of time soaking with a good carbon remover like butchs or boretech carbon remover

Looks normal for 800 rounds to me. I try to avoid trimming brass as the 1st firing afterward always has higher SD and ES. so having room for the brass to grow is a positive.

I'm having a difficult time deciphering what angle you took the pic. Looks like it's being viewed from the chamber angled to catch part of the bore? Regardless, lots of bronze brushing, iosso then repeat. Possibly jb for a stubborn area.

Much appreciated for your insights and experience guys.
