case scratching reloading 223

[NOTABIKER]

I was reloading 223 for my S&W AR ,while i was inspecting for cracks i noticed a faint line in the case at the neck . Every case i shot last weekend had this scratch. It is very light but enough to feel with your fingernail. The rifle functioned like a charm. So i took out a batch of 223 that i shot before my last outing and NO scratch.
I am conserned but i also do not want to overreact . What i did is i put a stainless bore brush a little larger than 223 on a drill motor and ran it back and forth in the chamber for a very short time. than i patched the chamber and bore with gun oil. Ran some clean brass in and out of the chamber and inspected it. The scratch is still their, This rifle only has maybe 200 rounds threw it and i love the rifle.
Should i just live with it as long as i inspect my brass after every outing ?. I am not one to take my stuff to a gun smith, i do my own minor services. I am surprised that whatever is in the chamber to scratch the neck of the brass did not come out with the stainless brush.

Is it a scratch or a burr?

[NOTABIKER]

slight scratch from the tip of the shell to the neck ,maybe 1/4 inch. I can fully chamber a shell by hand and remove it with no effort. I tried to look in the chamber with a flashlight and a bore light but it was too difficult to see anything. I think i am just too fussy .

Wherza pitchers?

I've picked up tons of brass with dings in the neck and reloaded them with no problem. An uneducated guess is that they're being scratched or dinged when they are ejected, based on some other threads I've read.

Can you post some photos?

thanks for the interest in helping me. I am a stubborn 70 year old and resist technology. I have nothing that would zero in on my chamber to take a pic.

Forget the chamber . . .

Do you have a pic of the brass with the scratch that you are talking about?

That is far more important.

[NOTABIKER]

that i can do . I am not as conserned with the scratch getting on the brass as i am how did something stick to the chamber enough to stay in place to scratch the brass. The scratch is so lite you probably would laugh at me posting it.

[JackEllis]

This might be an idiotic idea because I'm totally unfamiliar with gas operated guns but...

Can you chamber a case and then manually eject it gently enough that it won't strike any part of the gun? If you find the scratch, then it's inside the action. If not, try again only eject the case forcefully enough to strike the gun and see if the scratch is present.

When my upper was rebarreled, I was getting a very light scratch on the neck of the brass but most of the time the longitudinal scratches were on the case body.

It was caused by the new barrel extension. I think it went away after 1500 rounds.

Then again I am not saying that what happened to me is same as what you are concerned about

This^^^^:
In the barrel Extension you see the feed ramps. As the bullet slides up the feed ramp, you see a sharp tip on the feed ramp. Take a small file and take the sharp edge off the tip of the ramp.
Don't get crazy. Just take off the sharp tip.
I do this to all my AR barrels.
Opensightonly . Reminded me.

Chamber and extract without firing, no gas system to plug.

"get over it" isn't helping, actually, nothing in your post helps. Please stop attacking others. If you have nothing useful to post skip along to the next.

The scratch is probably from the feed ramps. Drop an unscratched case in the chamber, close the bolt then extract carefully and check for scratch. If none, put that round in the mag, chamber it, extract carefully and re-inspect. If it's something in the chamber I would contact the manufacturer. If it's the feed ramps, hard to say without seeing the scratch and knowing exactly what part of the ramp is causing it.

If there's a scratch/gouge in the chamber the brush on a drill is very unlikely to get rid of it. You'd have to remove a fair bit of metal to get rid of it that way which would require some grinding media. Not something I would do.

Still no pitchers?
