deformed shell casing

spotty bobek

Shooting a GLOCK 23 and noticing the casings are
out of round at the open end. I don't think it matters
what brand of pistol anyone know what the problem may
be without going to a gunsmith?

could be a lot of things.

What generation Glock is it? Earlier generations had bigger chambers for better feeding, at the expense of "bulged" brass. That could be it.

Did it always do it? or did it just start?

What brand of brass is it? and does it do it with other brands?

Is it factory, or reload? (if reloaded, for the love of God dont use lead bullets in a factory Glock barrel!!! Jacketed ONLY!!!)

spotty bobek,

I don't really see a problem, as long as your pistol is functioning 100%. If you reload, the brass all gets deprimed, and resized, then expanded, anyway. If it is not broke, do not fix it, or have anyone else fix it.

Most all semi-auto's, rifle, or pistol, will deform the brass, at least a little.

Federal 180 grn jhp hydroshock.Just noticed the problem, never noticed it before. GLOCK third generation. The casings look as though they are hitting off something and denting.

As the extractor pulls the fired case out of the chamber, the slide is in recoil mode. Eventually the base of the fired cartridge hit the ejector that's mounted on the left side of the frame/receiver.

This causes the cartridge case to pivot to the right out the ejection port.

Perhaps the front portion of soft brass cartridge case hits the side of the slide prior to being fully ejected?

I've reloaded various kinds of bent and fluted, ( H & K, 10mm, MP 5) brass in the past. The stuff might look ugly when you pick it up off the ground, but it's still reloadable. Nothing to worry about.

I reload a lot of used brass. I probably see 15-20% that has case mouth dents. It's not uncommon, some guns do it more than others.
