Stupid question time. I got a revolver in 45ACP. It has miles of throat,so. I don't have to do them short to fit a magazine can I leave them long, thusly being able to get more of a slower powder in so as to go from a crack to more of a boom. Unless I'm missing something a 45ACP just barely hanging onto the projectile should have the room to increase powder/fps
 
.45 ACP wasn't designed to be a magnum load. If you want more of a boom you should've bought the .45 Colt with the longer case.

Whatever you do don't exceed maximum recommended loading pressures.
 
Exactly what revolver in .45ACP did you get?

Don't play around trying to overload a non-magnum cartridge. Overloaded revolvers wear out...that's why magnum cartridges and the guns to shoot them were invented. I have an old S&W 1917 revolver and I won't shoot anything but mild handloads through it.

Stick with established loads. In a modern revolver you can safely use loads at the top end of the power range, but no more than that. If you want more power, get yourself a nice .44 magnum.
 
Seems to me a crack is faster than a boom anyway or at least that is what I noticed shooting a Walker repro at 1135 FPS as compared to subsonic loads.
 
None of the smokeless powders will give you want you're trying to do. Also many of them are not intended to be used in the small volume of a handgun cartridge. And of the powders that ARE rated for loading .45ACP none of them are slower enough to matter.

What you want to do is load up the cases with black powder or Pyrodex to get the soft but firm THUMP! sort of ignition that you seem to be wanting.

If you do this there's no reason not to load the bullets a little long for more room for powder. You can also go with some 240 to 255gn bullets to build up more pressure and kick. After all you still won't have the length of the .45Colt even if the bullets are barely in the lip of the case. Just be sure you put the bullets in far enough that you can get a good hold. They need to have enough grip to avoid walking out and need enough grip that SOME pressure can build up before the bullet leaves the casing.

Also with both black powder and Pyrodex you MUST load the case full and seat the bullet on the powder with light to moderate compression. NO AIR GAPS ALLOWED! ! ! ! ! Fill to 1/8 inch or 3mm down from the mouth then seat the bullet in about 3/16 or 5mm to give a good compression to the powder charge. That's as LONG as I'd suggest you try. Any less and you won't get a good bullet hold.

The powders you want for this are FFFg or 3Fg in black powder or Pyrodex P (P for Pistol). Also note that the fouling left by both is a corrosive salt. So you're looking at the hot soapy water washup at the end of EVERY session. The good news is that since this is a single action gun with open ends on the cylinder this cleaning is a breeze.
