Ruger American gen 2 flat lines on brass

[MaxRager]

Once fired brass has flat lines/spots running the length of the brass.. Any ideas what this is? Unfinished chamber from the factory maybe? It's my friend gun and shoots decent but **** the brass looks horrible and is very difficult to resize.

Looks like a Friday afternoon chamber job to me… have a local smith polish it or I'd send back to Ruger.

That's what I was thinking? I know ruger hammer forges barrels but the chamber as well?? As bad as it looks. Can't believe it shoots as well as it does!

Surprising as all reviews on Gen 2 have been positive. I was waiting for one in a 7-08. Please keep me posted on solution. Thanks

I know others with Gen 2's this one is unusual..

That's crazy. I'd contact Ruger about it. Trying to polish that much out of a chamber would likely ruin it. Never seen anything like that before.

Call Ruger, they will fix and even pay for postage both ways.

Ruger has GREAT customer service. Use it.

Looks like burrs around the back end of the chamber scratching the brass, I agree with previous posters. Box it up and send it back to Ruger. My gen 2 doesn't have any issues that I have noticed and so far, shoots very well with limited load development.

PLEASE let us know how it turns out.

I have a bolt action mossberg that takes AR style magazines and when I cycle the bolt back, the catch on the bottom of the bolt that feeds the next round, drags across the cartridge below and leaves a line across the shell. While this drives me crazy, it's part of how my rifle works. I'm not familiar with the Rugers, but wasn't sure if this info helps or not.

Did Ruger start doing HK-style fluted chambers and forget to tell everyone?

All joking aside, unless you have your own lathe and 7-08 reamer, contact customer service and let Ruger handle this one.

Are all the rounds fed from the magazine?

If so, my guess is that the lips on the mag are sharp and marking the brass as it is stripped from the mag.

A light touch up with Emory cloth should fix it.

It's not the magazine.. The lines cover the entire case. The pictures are of both sides.
