Powder burns on .45 casing

[inky0ct0pus]

Shooting a Glock 21 today I noticed that on every casing, there were significant powder burns on one side. The burns go down to a little over half-way.
I shot three different brands.
Federal 230gr fmj - all casings were burned
Winchester 230gr fmj - all casings were burned
Federal Hydro-shok 165 gr hollow point - less burned, but still some visible.

The gun functioned 100%.
Is this something to be worried about?
Here's a picture of one of the federal casings. They all pretty much looked like this.


Thanks

Nothing to worry about. It happens when the cartridge doesn't seal very well with the chamber. This in part do to a low pressure cartridge and a large chamber (which is intentional to help with reliability).

Thank you for the help! I wouldn't have even noticed, but a gentleman at the range picking up brass for reloads said he hadn't seen it before.

Glock chambers are about .008 oversize so they will feed garbage ammo you find on a dead United Nations Trespasser* who thinks the world-wide-gun-ban applys to the citizens of the United States.

Your ammo looks normal. Have fun. The Glock 21 is a fantastic weapon.







*Yes I know he will probably have 9MM on him


OH...and Welcome to Cal Guns....! Plenty of nice people here.

Well, to be honest nothing concrete has surfaced BUT (putting on my Tin Foil Hat) the UN GLOBAL GUN BAN TREATY was on the table.

Google UN Gun BAN. etc.

And yes, UN troops wear blue helmets... and carry 9MM HK P2000s....

Time for coffee

Weird. I think I'd be more shocked to see a perfectly clean piece of brass. Yours looks totally normal.
