What is doing this to my brass

[Jig Stick]

I have a stock Sig 556. I was shooting some Lake City XM 193 out of it. What is fucking my brass up? The extractor? How can I fix this?

Fucked up neck



Small dent and scratches on body

Called normal, from a gas gun. You can install a weaker spring in the ejector but, unless you know what your doing leave it alone. It will all come out when you reload the brass.

It's happening upon ejection. The case is being flung with tremendous force and is colliding with the back side of the ejection port first (case body), and then with the side of receiver (neck).

Block this area with a glove, hat or something else such that extracted brass will not re-contact the rifle and fire a few and you will see I am right.

The upside for you is that the pictured defects are not a problem at all if these are not the rounds you had your heart set on winning with at Perry this year. Just resize them and load again.

Perfectly normal and nothing to worry about, the neck will straighten out when you resize it and the dent is from the deflector or the port and will be ironed out when you fire it again.

Lots of rifles will do that.

Thanks guys. I RARELY shoot my ARs. And I don't reload them, but I'm going to start. I thought this brass was garbage. If the dies can fix them, then I'll keep saving them. I thought about changing to a heavier buffer plug and spring to see if that would help. My Bushy CAR15 eats the same ammo and doesn't do this to the brass. I wonder why

The neck can be from the Brass hitting the ground. All of mine are like that when I go to a Range with Concrete Ground. The dent happens during the bolt cycling. It's perfectly fine but a little pain to get it ready for reloading afterwards. Gas Guns are Hard on all the Brass.

Yep.... It's all normal. Different ejectors will cause it while others won't. Banging off the brass deflector, etc.

Some shooters put a wrap of fuzzy side Velcro on the brass deflector which seems to help a little. Give your deflector a black fuzzy Velcro blanket and it wont even be seen.

That doesn't look to bad, you should see the brass that comes out of my PTR91, when I can find it…it normally goes about 15yds 2 o'clock
Get a brass catcher, cut to fit piece of rubber or some moleskin, or velcro stuck to the deflector. gtg.

 

[tackleberry2000]

I got a Slashes heavy buffer in mine and all i get is the ding in the side. Not quite as bad but still there. As for the neck all of mine are undamaged.

This has worked well for me on a couple of AR's.

put fuzzy Velcro on the brass deflector and get a brass catcher (especially if shooting on concrete) of some sort and you will have no issues reloading.... also, some AR's have a "break in" period for dented case mouth issues... My LMT used to do this at first, but after about 500 rounds my brass is ejected just perfect now.

If you go with a brass catcher Ive been having a good experience with this one

Tactical Brass Recovery. Brass Catchers made by shooters for shooters!

More expensive than other solutions but I swap it on two guns and it folds down flat to pack in my range bag. Nice not having to look for holes in the snow to recover my brass.

I thought this brass was garbage.

I've expanded case mouths that have been smashed into gravel with car tires. They were dented all over the body but they didn't crack and the head was good so I said "fuck it". The all feed, fire, and eject. They were used for 3G short range stuff. They all hit the target. I could not tell which ones were smashed or not of the ones I recovered. 55K PSI is magical.

If you're concerned about blowing your gun up this might not be for you. The point I am trying to illustrate is a dent hear and there doesn't make a bit of difference it the reliability department. There could be an argument to be made for the accuracy department.
