Holy cow, 40,000 PSI. Never heard of this cartridge before but it looks neat. This link says there's an 80 grain bullet with a muzzle velocity of over 3000 ft/second... really?! Wonder what length barrel that's coming out of
Looking a little closer it says 5.5"... wow. It also says the source is from the Rowland company so I'll take that with 80 grains of salt. Can you really beat rifle-length 5.56 muzzle energy with a 1911?

Holy cow! That's the first I've heard of the 80 grain loads. This is much higher pressures than normal .45 though. Not safe to shoot in a normal .45 without the specially hardened chamber, barrel and springs/compensator. Hence the slightly longer case to prevent accidents. The other numbers seem accurate from the table that I have of standard loads. I can't imagine the 80 grain would be very accurate past 15-20 yards though. Both mine shoot the 185 grain very nicely out to 50 yards, haven't tried further yet.
