I don't know how a rifle powder would blow up a magnum pistol. You might be able to do it if you just put a few grains of slow rifle powder in the case and got a pre-detonation.
More like a shotgun powder instead of a slow pistol powder.

It has to do with the time the bullet takes to leave the barrel. If too much time under pressure, the rifle powder then has time to reach its much more powerful pressure curve.
I nearly had an accident myself doing this many years ago when I left my powder measure on my Dillon 550 filled with AA#2230 after loading a bunch of 5.56 ammo. Several months later, when I set up to load some .45acp, I somehow convinced myself that my powder measure contained AA#5 pistol powder. (Both were ball powders that looked to the naked eye as exactly the same.) So I started dropping 8.0 grain charges of powder under some 230 grain projectiles. That should have produced a mild velocity of 850fps with relatively light recoil and noise. But when I went to the indoor range at Shooter's World and started firing the first magazine, I was getting HUGE blast, BRIGHT fireballs and MAGNUM-like recoil. I only fired 5 rounds and then stopped, because something was definitely wrong. I knew I had somehow screwed up my propellant charge, but didn't know what I had done. I later figured it out. And thankfully I was dealing with small enough charges the gun held together. But if I had dropped slightly larger charges, say in something like a .44magnum, I could have easily had a KABOOM.

All about that time/pressure curve it is.
