There's no telling what this fellow had in mind when he started out.

A Great Little Device, now identified…
Thanks to a TGZ visitor, a device I've been using for years, a trophy of a long-ago SHOT Show, has been identified as the Hide-A-Gun.
But, and this is a big but, will ya look at who the manufacturer's top-listed link is!

H&K USP45 Kb! Update:
Our fortunate (in that he still has a shooting hand) protagonist did a pre-mortem on some of his remaining "Gun Show" reloads, and discovered that the charge weight of the flake propellant was a reasonably uniform 8.3 grains.
Here's a full-size image of the accompanying thumbnail… kinda looks like Hercules Red Dot, and the Alliant site lists 5.0 as the charge weight for a 230-grain FMJ.
Any other ideas?

I don’t know where that ammo company sources their brass, but if they get it from local ranges, they could be using cases that were reloaded a handful of times prior to them touching it. I’ve seen some rather bulged cases left behind the local range that should be left alone. It could be that some of those very weakened cases got through their inspection process (if one exists) and after depriming and resizing, they are loaded up like normal. At that point, even a standard pressure load can cause the already weakened area of brass to let go.
Some of that remaining ammo should be pressure tested. That would narrow down the possibilities of what happened. Someone should send some of that ammo to Pete over at Cor-Bon. Supposedly he pressure tests and he is more than familiar with kBs.
Or a better option... Charlie has an Oehler system :wink:

I agree that it looks like Red Dot and that 8 grains is way beyond too much.
No Fernando I ain't gonna blow up my .45 barrel.
The failure picture says to me that it is almost certainly a case rupture in the feed ramp and if the load was as stated there really isn't much to investigate.
When I have some time I'll crank up the Quickload program and see what the theoretical pressure might be.

According to "Quick Load" the pressure of that load is in excess of 55,000 psi. That's only double the normal maximum.

In the shot of just the barrel, split open, I notice a lot of linear silver streaks extending down the barrel, starting just a few mm from the chamber. I took this to be leading. I find it hard to imagine that this degree of leading was an effect of the kB, but I certainly wouldn't be surprised if it were the cause.

I think so too Tim.
There have been studies that show leading can lead to disastrous pressure increases- especially is someone fires a jacketed bullet to "clean the lead out". This is way up there among dumb advice sometimes given.
