I recently bought a Ruger Blackhawk Flat Top New Model with 45 ACP and 45 Colt cylinders. I did some research to find that my particular revolver has a medium frame which can handle hot loads BUT the cylinder walls are thinner. The 'New Models' aren't as strong as the original Blackhawks. As such, I only shoot SAAMI loads.

Now here's the kicker: most ammo manufacturers don't publish the psi of their rounds. I found some Underwood 45 Colts which were higher fps and muzzle velocity but still 14,000 psi (Underwood also makes +P hot loads). Since none of the info on the box or website gave the psi, I called them to be sure I was using safe ammo. As already stated, +P and Buffalo Bore "++P" ammo will fit my revolver but I am not interested in blowing up the cylinder.

Unfortunately, some folks "get them a gun and wanna shoot somethin" without proper instruction or understanding. When it comes to hot loads, they can qualify for the Darwin Award fairly quickly.

+P ammo has been around for a long time. I shoot +P in my 9mm (not quite the same as Buffalo Bore though). I have to imagine that the ammo manufacturers would have been sued by now. I know that Underwood puts a disclaimer on their website for +P (aka 'Ruger Only') ammo saying you have to have a large frame revolver but it takes a lot more time and effort to really understand.
