Used 40S&W cases

[v-man]

Not sure if this belongs here or in reloading but here goes.
I was recently made aware that some used 40 S&W cases have a tendency to bulge beyond what normal resizing can correct as as such are not good for reloading. I have saved all my 40's for several years and plan to reload them when my Hornady dies finally come off backorder. Is there really a problem or not? What is the real story?

Ahhh, the famous Glock Belly. Some cases fired in the earlier Glock barrels had a tendency to bulge excessively in the less supported feed ramp area. Those I full length resized worked fine. It's easy to overwork the brass in the area of the bulge resulting in a blown case head, so check your brass carefully. Actually, it's easy to see the bulge with the naked eye, you might be ahead of the game by chunking those. My .40 S&W reloads are on the moderate side, and I have not had any problems with using the cases after proper resizing. It's rare these days finding fired brass with this bulge. Check your rounds with a chamber gauge after reloading to insure they chamber, keep your loads on the mild to moderate side and all is well.

ive heard it said  but have loaded .40s for over 10 year and have loaded thousands of brass i picked up at the range shot from about every gun imaginalbe and have never found one i couldnt use again.

I have been loading 40S&W for 10+ years most of which were shot from a Glock 23. I've never experienced the buldge problem. I just finished processing 1000 rounds of range brass from LEO Brass and found 3 throw aways. I don't think you will have a problem if you inspect each round before and after sizing.
GOOD LUCK and GOOD SHOOTING!!!

I load all my .40 in range brass. I can't remember the last one I noticed with the bulge. My last loading station on the press contains the LFCD. After passing thru that, they all chamber and function just fine. I think the concern with the "Glock Belly" in .40 brass is pretty much a non issue these days. I just load it and shoot it!
