Possible Damge to My Stag 10

split necks are a sign of over pressure yes. What ammo are you using?

Brass is pretty soft metal. It's not gonna do much cutting of carbon steel barrel chambers. That was the general idea behind using brass for cartridges. Maybe you have a head spacing issue or some rough injection pathway if your rounds are getting dislodged. Gas guns are sensitive and finicky. Ammo varies and sometimes the brass between manufactures is different in strength. Gas guns generally benefit from tougher brass to reduce flexing/deformation of the case. Some ammo is also sealed with an adhesive on the neck to prevent this also. Ie mil type ammo.

I'd try some other ammo before freaking out.

I don't know if I made it clear enough, but the necks were split before I even loaded them. This is new unfired ammunition with split necks.
 
In reality it should cause no damage if you fired only a few rounds, if you fired lots then....maybe you should be looking at what your putting in your gun.

Do you still have loaded new ammo with split necks? post some pictures? if they are all fired then how do you know it didn't split after you shot them.

If your bullets are being pushed back after loading them, the bullets are too long for your barrel, they are probably hitting the lands. OR they are being pushed in by the feed ramps when being loaded into the chamber.

more info would be helpful. caliber, bullet grain/manufacture. Is this a built stag 10 or a factory one?

I bought 480 rounds of the stuff. After going through the 360 I have left, nearly a fifth of them have split necks, to varying degrees. Some are into the shoulder of the case. Of the 120 rounds I fired, 13 had split necks.

Let me ask you, do you thoroughly inspect each round of factory ammunition that you fire. If you do good on you.
 
The necks were split before firing? If that's the case anything is possible. But I would run some decent ammo through it and see how that shoots, and examine the spent casings. If there is any damage to the chamber it will imprint on decent brass cased ammo.

What kind of ammo was this? definitely post up some pics.

Remington UMC 308 150 Grain Ball. The pushed in one is one that I had chambered, and then manually ejected.

On bulk ammo I don't check anything because I'm aware of the consequences of fireing bulk or surplus ammo, I thought we were talking about a precision rifle ammo since there was not a lot of information given.

I personally would not worry about it, I would contact Remington with pictures of the ammo. They need to know if they had a bad batch of case tempers so they can do a recall.

Clean your stag 10 chamber and fire good ammo out of it, check the case and see how it looks, but chances are everything is fine.

do not use ammo from that batch untill you hear from Remington.

Thanks for the warning, but I have no intention to fire anymore of that ammunition, now or ever. I have already contacted the retailer. I will be discussing a full refund of the purchase price when I hear back from them. I have contacted Remington as well. I gave them the Lot number.
 
There have been plenty of split necks with no damage to the firearm. A bullet seated deep like that will increase pressure by quite a bit under usual circumstances- like if the neck wasn't split. With the neck split everything is probably really loose so if you did indeed fire a few rounds like that, likely nothing happened.

I would clean it and try some better ammo, and get remington to replace your ammo.

Thank you. The retailer and Remington have been made aware. I am awaiting a response.

Without naming the retailer, a recent purchase?
 
I had a case of a thousand umc with the same issue there where 280ish split cases. The reason was improper annealing.
The buttet being pushed in is from the fact there is no tention on the bullet. Phone remington and they will replace it for free. Atleast thats my experience.

Thanks. I can't see how they wouldn't. My biggest concern, even though I have been assured by posters on here, is that the gases cut the chamber, or an over pressure situation occured. I think I will have a gunsmith rule either of those out to settle it for me.
 
Have you stripped your rifle, cleaned the chamber and inspected it?
See any damage in the neck area?
Does your 'smith have a borescope to examine the chamber?
