While shooting my Remington 700 VS 308 with Federal Premium 180 gr. Nosler Partitions I have copper ring staying in the barrel after some shots, any clue on what is happening?

How do your cases look? Is the neck all right?

Are you having any trouble opening the bolt? I have had cases chear and leave the case body in the chamber, and have split necks, never seen this before though. Very interesting.

Africa--

I'd IMMEDIATELY contact Federal and show them the picture.......I'd also get a new barrel from them. The chances are VERY good that you have a series of rings ironed into the bore whice effectively ruins the barrel.

I'm curious. How'd you find them? Where are they? How did you remove them? Does it happen every shot?

Very odd. Let us know what Federal has to say about it.

Is the rifle new? Does/did it do this with other loads? Where in the barrel are you finding these rings? How is the accuracy? Any chance to fire those loads in a different rifle to see if you can "duplicate" it (maybe determine rifle vs ammo at fault)?

I admit, I have no idea, but am definitely interested....

If you try to shoot in another rifle make sure that you tell the owner first why you are testing the load in it, and be aware that Federal, if it is their fault in the end, might not be willing to replace a second barrel if it was your troubleshooting and not theirs.

Are these reloads and do you debur? I can't really tell but if these are reloads they might just be a ring shaved from the bullet by the case mouth. However, if it is in the chamber I can't see how they could stay there and not get pushed out by the bullet, so perhaps they are being shaved into the brass by the bullet, perhaps from the case neck? Another possibility is maybe it is the case mouth separating due to a crimping problem, but I am really swagging it here as I have never seen anything like that ever.

I contacted Federal and they told me to ship the remainings boxes of rounds to them along with fired.

On the first piece I was working the bolt after I fired a shot and was putting another round in the chamber when the bolt would not push forward all the way.

After that (next 10 shots) I was shooting and cleaning in between shots and on two occasions pushed the copper piece right out the front of the gun.

Accurracy has not been affected but I'm unsure if the barrel did get damaged. (This was on a factory Remington barrel.)

Mark- These are factory Federal Premium bullets.

If the barrel was damaged, you could SEE a ring in the bore, or feel one or more very loose spots in the bore when you run a cleaning patch through it.

I would keep a box of the catridges and a couple of the fired ones. Just in case the others are "lost".

Africa,

If you were to chamber a round in a weapon with too short a throat, it is quite possible that as the bullet was pushed back into the case, that the mouth of the case could slice a small ring from the bullet. How it would remain undamaged and intact would be interesting to know.

You might pull the firing pin (to be safe) and then chamber a few of the rounds to see if this is happening during chambering. Maybe measure the OAL before and after chambering to see if the bullet is being pushed back into the case. Who knows, maybe Remington screwed up and produced a "short" throated gun for a change.


Good luck,

Three things could be wrong:

1. You are shooting handloads that have not been trimmed and pressures are up and that part of the case that is forced into the rifling gets detached by the bullet at the shot..

2. The neck of your chamber is not within specs again causing the above

3. The factory ammo is too long and out of specs, this is unlikly I would think.

I would get a chamber cast and have it measured for specs.....

Gentlemen! How many of you are betting men?

Assuming this is a new gun, I'm betting it's not fully chambered. I've seem some amazing things fall out of Remington boxes....
