Brass Questions

[King31]

Shooting out of both my 18" GB Faxon and 12" PSA Grendels yields brass that comes out looking very rough. Can anyone chime in and tell me if this looks normal? The 18" has a lot of promise in being a real shooter, but I did not have this problem with my first Grendel. Thoughts?


I can add some better pictures if it would help.

That does not look normal at all. I can't believe the marring on the body and gas blow by on the neck. Both signs of a chamber that never should have left the place selling the barrel.

If I may ask who made the barrel and also, what brand of sizing die and case lube are you using?

This is the 18" Faxon Group Buy Barrel from a year ago. I've had it sitting around for a while. The brass is from Factory Loaded Hornady Black and AG. For what it's worth I use Hornady Dies and One-Shot.

Need to let one of the gunsmithing types like LRRP52 or Sticks to give advice on this one. If LRRP52 does not see this thread, let me suggest you write him back channel and ask him to look. Sticks too since I believe he is pretty good at troubleshooting this type of thing too.

It certainly looks like very poor workmanship and no quality control was put into the chamber.

You might try making sure that your chamber is clean and dry, oil or case lube on the cases or in the chamber can make those strange markings.

I plan on doing that before going out the next time. This Midwest weather is going to be brutal for a few days. Appreciate the responses

If it were mine, I would take one of my 6.5 Grendel chamber brushes, wrap a patch on it with Flitz, J-B's, or light polishing compound of choice, and spin it on a cleaning rod with a drill going back and forth in and out of the chamber rapidly.

Then see if the marring and scratches continue.

There have been a couple of post where Faxon barrel chambers were rough. Most were attributed to the Nitride process leaving residue in the chamber. A few Forum members polished the chambers themselves and a couple of forum members contacted Faxon. Faxon had the members return their barrels for inspection/repair/replacement.

Here is one link to a thread with similar issue.

I'd say you are on to something. I'm guessing you copied the wrong link though. Will this go away the more it is shot? I cleaned the barrel thoroughly yesterday and shot 5 rounds with the same results.

You won't lap in a chamber with brass. It won't go away the more it is shot.

You might as well try the polishing technique LRRP-52 provided. It won't hurt anything even if it doesn't work.

Sorry for getting the wrong link King31. The first link is the one I intended in the previous post.

This second thread might be worth reading.

I was thinking the same thing, I have run into that issue with other calibers occasionally over the years and that is how I resolved it.
