interesting. i'm not a reloader, but Sfguard probably knows what's up with that

The pieces of brass in the picture are Winchester White Box, once fired out of my G22. I was running the brass through Redding dies on my in my Dillion 550B. I couldn't feel much of anything, except that it was a little harder than normal to for the brass to cycle through the sizing die. The end result is that where the bulge was, it has now been pushed in (concaved) a little bit and the outside of the brass has been shaved. I havent run the brass through a brass buster yet. But, I did get a Redding G-Rx for xmas, which is the equivalent to the Brass Buster. Now I just need to get around to running the brass through the G-Rx sizer.Unfortunately, I can't tell what was happening from those pics. Is this brass you had loaded then pulled? Or is this brass you hadn't loaded yet? If it was something you were loading did it feel kinda like something was getting caught? And have you ran any of this through a bulge buster?
Some of the brass wasnt mine, but the Winchester for sure was mine, and it was shot from my G22. Also, my G22 is a gen2 pistol thats nearing 17 years of age and has passed I dong know how many thousands of rounds through it, so there is some wear. I think though, it might just be time for a new barrel, because also, I've got over 6k of 40 cal lead bullets my dad gave me that Id like to to load and shoot.The more I think about this the more something bothers me about the brass being that "bloated". (Can't think of another term at the time) Boomer did you shoot this brass or is the brass in question something you picked up? The reason I am asking is if it is 40 brass and you say it is so I am sure it is(not implying anything here just saying) I wonder if someone shot it in the wrong caliber gun.
Shooting say the 40 in a 45 or something. Could have been a new shooter and didn't know any better or something. That would also explain why it is only certain brass your having the issue with. IE what he/she had with them that day. That is the only thing that I can think of at the moment that would cause the diameter of the brass to be that far off.
I have to admit it has me stumped. I would have to have the stuff in hand to look at and try out a couple of times. It just shouldn't be doing that, Obviously. I can't help you on this one buddySome of the brass wasnt mine, but the Winchester for sure was mine, and it was shot from my G22.

Let me know how it turns outYeah, I'm not too sure either. But I have run the brass through my Redding G-Rx die to resize the bulge. So, I'll see how it goes when I get them loaded up and run back through my G22.
yeah the loose chamber dimensions coupled with diminished chamber support make glock fired brass less than ideal for reloading. you can google "glock smile" and find that's the nickname given to the bulge at the bottom of the brass. i noticed some of my full power 10mm brass has the "glock smile".Truly the noob here, I've only been to the range once with my new (well, not any more!) G-23, and fired off over 300 rnds of several factory brands, all new. I picked up a few handfuls of my, and others 40cal brass when I was done. I don't see any brass that does not have some bulge or mis-shape to it. I would not trust any of it for reload, unless it were all resized to proper dimensions first. Brass is soft. Certainly too soft to avoid expansion under chamber pressures.
Factory chambers can't be so precise, as to risk getting some brands of ammo stuck on the way in or out. So how can expansion not happen? Gotta know, gotta learn, gotta grow!
