Much as I love Brownings, they suffer from the same issues of lack of case support as a Glock MIGHT
And what usually happens with them, is that if the case fails, all the gas just blows the magazine out the bottom. the gun is rarely damaged, maybe the grips split. the first picture there is typical, but unless something else is unseen, that gun could be fired again.
the others, I submit are major reloading mistakes, not just a half grain or such over. Or the loads in question had to be giving lots of warning signs.
If the 38 Super isnt running as much pressure as the 40, I bet its darn close, but the guys running race guns, do have barrels with supported chambers to fudge a little on the hot side.
I have 3 different 38 supers, none with supported chambers, and I have had no problem with any book load, though some flat primers are showing some pressure signs, no case bulging is found.
I say again, I dont think minor errors are causing the 40 blowups. Minor errors of a half a grain over might cause an occasional web bulge, but if guns are coming apart, its cause the nut behind the trigger went to sleep big time.

I bought a new 35 and a 1st-gen. 23 about a year ago and started reloading for them before I heard anything about 'chambers not fully supported', and this thread is the first I've heard that the 40 is dangerous to reload. The 40 is the 1st handgun cartridge I've ever reloaded, and I'm quite pleased with my results if I say so myself.
My old 23's barrel supports the cartridge body fully, the same as my new (3rd-gen.) 23 (bought yesterday) and my 35 do.
I bought the Sierra manual and downloaded the Hodgdon data. I bought 3 different powders and use each for particular purposes. If you're loading PD ammo, I suggest you seriously consider using Hodgdon Universal powder, since it apparently has no Muzzle Flash, at least according to this... http://findarticles.com/p/articles/mi_m0BTT/is_190_31/ai_n27380935/
I know that the few occasions I've shot in the gloom, I can see some MF from loads NOT using Universal, whereas loads using Universal have no MF.
Go slowly, be careful, and shoot more now for the same money.
