G21SF and spent casings question.

Maybe i'm a little paranoid and it's just cheap bulk ammo but, when I shot my Glock 21 today at the range today it seemed that the empty brass was burned on one spot from top to bottom more than usual, or I just haven't noticed it that dirty before. I picked up some .40 brass someone had shot out of a handgun and they didn't look nearly that bad. I guess I just want someone to tell me not to worry about it. I do have a pic.

don't worry about it. Its mostly a factor of the type of powder used as to how dirty the brass is. You may have a slight gap (talking nanometers here) on one side of your barrel that allows the hot gasses to take a path of least resistence down that side of the brass, but nothing is perfect, and as far as I know, this sort of thing does no harm to the gun or the user.

Nothing to worry about. Go shoot some more!

Just flames out more on that (gulp) unsupported part of the chamber, yes?

Well thanks, it just seemed burned more than other brass I have fired out of autos. Probably because of the "unsupported part of the chamber" on the Glocks but I hear that helps them go bang every pull of the trigger.

Also I have mostly shot Federal target ammo out of it and haven't noticed that bad. I keep it loaded with Hornaday Tap 230gr. +P for carry, I have shot a few mags of that through it but it's high dollar ammo so I don't have alot of range time with it.

Not powerful enough to fully expand the cases. Had it happen to me with some factory ammo and very mild reloads in 40 S&W.

Not a problem.

I did a Google search on WWB ammo and found many comments about how dirty it shoots. Some dude on some gun forum had the exact same result and concerns with it, I think he was shooting an XD. Anyway, the ammo functions good, i'll just expect it to be dirty shooting ammo.
