The battle of the bulge...
« on: August 09, 2013, 08:23:26 am »
I received my first order of brass from Oncefiredbrass.net yesterday (2000-.40s&w). So, of course, I couldn't wait to start to get going. My reloading table isn't quite done, but I brought it in and fastened the press down anyway to test everything out. I have heard about "Glocked" rounds, so I started sorting the first 1M accordingly. Came up with about 25% normal and 75% Glock-fired cases all of mixed headstamps. Great. Oh well, the price was right, beggars can't be choosers and all that. So I de-primed, sized, and re-primed the regular cases with no problems. My Lee bulge buster kit is still on the way so I figured I could de-prime and size all of the Glock cases so they would be ready when it arrived. Just for curiosity's sake, I checked the O.D. on the newly sized regular cases to compare to the Glock cases. Both had been ran through the de-priming/sizing die already. What!!? No difference in the first few of each that I checked. Here are the average measurements I came up with on both types of newly sized cases:

Mouth O.D.=0.418
Rear O.D.=0.422

The rear measurement was taken right below the rim. As you can see, both types of cases are larger at the rear. I know that the sizing die doesn't fully size, but I thought all Glock-fired cases would have an obvious and larger bulge. I am using a brand new set of Lee carbide dies by the way. Any clearing of the mists of ignorance would be greatly appreciated as I am just getting my feet wet in the reloading process.

    I also have Lee dies in .40. They don't touch the bulge. The bulge buster kit works really well, but watch the hopper. Cases like to push it up, then it falls off, then you have to chase your properly treated brass all over the floor.

    I've only had one non-treated case get stuck in my gun, but it locked up my STI Edge like a safe. Took us about 5 minutes to clear, with a live round stuck. :shocked

    I bulge bust all my .40 cases now. And I have a few gallons of it. Yes, it sucks processing all that brass, but it sucks a lot more having your gun jam up at a match.

    Thanks Outbreak. That's what I was expecting to hear but hoping not to. Is this just a common issue with .40? Also, I forgot to mention in my OP that I am about to start on 9mm and .45acp right after I finish the .40. Are bulged cases a concern with these calibers also?

    9mm isn't supported any better than .40. I've never had a problem with 9mm bulge in non-Glocks, and you can't "bulge bust" them because it's a tapered case whereas the .40 is straight walled. Wouldn't worry about it with 9mm unless you have a problem.

    The big frame Glocks (.45 and 10mm) have fully supported chambers, so no issues there.
