    I read a lot of threads where people talk about case bulge. I have 3 new Glocks (purchased new in the last 6 months) and reload for them all. I have a G-20SF, G-17 and G-23 RTF2. I do not load to max capacities for the range and use my stock barrel in all. I have not experienced any case bulge yet. I have shot my 10mm brass about 6 times and no issues. Has Glock improved their chamber support or is it because of my loads? Or Both. What have you all experienced?

    If you aren't having this problem now, don't worry about it. If you are paranoid about it, check your .40 and 10mm brass for bulges when you sort it. I wouldn't worry about 9mm (or .45).

    I've been reloading for a Glock .40 for at least 15 years. Use a chamber checker and when you end up with what I call ".40 S&W Belted" and the rounds no longer seat all the way into the chamber checker, use those as a range day for stoppage drills because they'll still feed most of the time. This takes probably 12-15 reloads for me and I've been loading close to max the whole time.

    Remember to crimp the casings with a pair of pliers so no one tries to reload them again after that one.

    Oh, you'll lose .45 brass before this becomes a problem.

    Thanks, I have over 1000 40 cal cases and shoot only 100-150 rounds a week and not always 40 cal. I have a case gauge on the way.

    Newer Glock .40's have better chamber support than older ones.

    I purchased a G23 barrel (to use in a G32) that was likely made in 2009 and don't notice any bulge at all.

    That is what I thought. I have not even seen bulges on my 10 mm.

    My experience echoes the above posted replies. When the case web gives out--the tempered part below the annealed portion--you need to pitch it. The absolute best description I've ever read of that is above--".40 Belted". That's exazctly what it looks like.

    My HKs, Berettas, And all other guns in that caliber cause case resizing issues in exactly the same percentage as the Gen III GLOCKs. They tightened up the chamber, IMHO.

    Redding makes a die that will remove the case bulge from 40 cases.

    Roll sizing will as well. It's a bad idea. At least with the case bulge and throwing them away when they get to be belted cases you stay on this side of safe.

    A couple friends have has case head separation and in each instance it was their own reloads that had been roll sized 20ish times.

    I'd rather just toss them when they get the band and no longer chamber reliably.

    Why is it a bad idea? Please cite a case/s.

    I've been roll sizing with a CasePro100 for a couple of years and haven't had any problems. It's a very good idea, as it saves the cases for further use.

    You will lose the brass eventually anyway.
