small dent at beginning edge of case shoulder of .308 win fired case

[p5200]

I bedded this rifle and now, there's one small dent in each fired case. It starts at beginning and goes foward about 1/8" I'm positive, no bedding got in the chamber. My thoughts are maybe it's a little wax that got down in there. I put a little on my finger and rubbed it all around inside the action. Probably a dumb thing to do. There's only on such dent in each casing. I just wanted to get more experienced opinions on this problem. If it is wax, how could I get it out? The wax used was Renaissance wax. Thanks folks!

Dents are all a little different on all 4 casings. The dents are different sizes wit a couple not very much of a dent.

IT CAN'T BE WAX. It is probably bedding compound. Wax would melt from firing heat.

Oh boy, I hope not. Would there be any method of getting it out? I don't have a bore scope to look in there. If I just chamber rounds there's no dent. A couple cases barely have a dent. I pulled a bore snake through but haven't fired it again yet.

Use a 45cal bronze brush on a drill for 20-30 strokes.

Just the chamber not, the bore correct?

How could bedding compound become present only at the chamber shoulder? The case dents appear very similar to those created by excessive lube on the shoulder during resizing.

Exactly, that's what made me think maybe that it's wax.

How hard does your ejector throw the case out of the action? If the spring has too much tension it could be slamming the case against the ejection port.

What ever was in there I ( think ) it's gone now. I took the .45 cal brush and ran it back and forth in the chamber quite a few times with some Bore Tech Eliminator on it. I then pulled my bore snake through it. I fired 2 rounds of the same batch of hand loads and they both look fine! I appreciate all the help folks!

To be honest, I've never pulled the bolt all the way back to eject a casing. I pull back slowly and grab the empty cases or I have trouble finding them for reloading lol!
