First off Ken glad you're OK.
It's also possible that an under charge could do this foul deed. Very glad you're okay :D

Good point.
Mudinyeri:
Glad to hear you suffered no lasting damage. Keep us posted on what you find as the cause.

Good Point. Could be just another Forum attention-seeker milking the tender sensitivities of the crowd. If I can figger out (a) my cell phone camera, (b) transmission to computer, and (c) Photobucket, I'll post some pics.
--- Quote --- try to use a powder that when its double charged, it overflows the case

Totally A-greed on this one. (FWIW, powder choices can be pretty narrow these days.)
--- Quote ---Just curious, do you load on a progressive or a single stage?
--- End quote ---
Single stage ancient Pacific press w/stand-alone single stage powder dropper. (Because.......I've always intuited that the S-S device is "more controllable" and less likely to mischarge, overcharge, double-charge, whatever. Maybe; maybe not. I do check powder charge weights about every 10 rounds or so and continually watch the vernier scale to ensure that it hasn't moved. Trying to be meticulous, which is why this KA-BOOM! has me somewhat confounded.)
--- Quote ---...low pressure loads like 9mm...

Might want to look that one up on the SAAMI data sheets. 35,000psi on 9mm; 38,500 on 9mm +P. (Agreed on the .45ACP; but the 9mm is a different breed of cat.).
--- Quote ---Did I gather you have reloaded a long time?
--- End quote ---
Yup. Metallic (rifle, pistol). Shotgun.
--- Quote ---How many times had the brass been reloaded?
--- End quote ---
Good question. By me, once. But....it's all range pickup brass. No way to really know. Brass should have an automatic reload hashmark on the rimface. So each time it goes bang, it makes a "check". I do the mandatory visual check on brass after tumbling: cracks, bulges, corrosion, and other etc. anomalies.
--- Quote ---It's also possible that an under charge could do this foul deed
--- End quote ---
Yes. Possible. The detonation phenom. Thought about it. No way to prove. Also, I've always wondered what happens if a live primer gets loose from a hand priming tool, falls into a case mouth, and gets a powder charge dumped on top of it. Coulda happened, I guess. So there are other possibilities, but the most likely one in this case may be powder overcharge. aka Operator Error.
Summary
I'm going to run the gun over to Tim Casteel, gunsmith, at Carl Jarl's this morning so he can take a look at it for a post mortem.
Once wuz a song, "I've Got a Brand New Pair of Roller Skates, if You've Got a Brand New Key....." So if any of you Fiine Folks happen to have a Springfield XDM40 frame laying around in your junk box, I just may have a slide and a magazine. We could put them together and see what happens with a new batch of reloads.
Just Thinkin'..............

Dan W:
.40 S&W is susceptible to case head blow outs when the brass is weaker than it should be...a hard thing to inspect for or control in the hand loading process, and the reason I don't own any .40 cal handguns
