I am reading all of these post stating that: "I use the same loads in both" and I am wondering WHY?

To me that is like owning a magnum anything and only shooting shorts in them. I understand the ability and need of shooting lighter loads, don't get me wrong. But someone that doesn't "wring out" their magnums at some point, needs a little help, in my opinion.

I mean, you wouldn't buy a 'vette and ONLY drive it 25mph would you?

The 45ACP revolver platform allows you a place to experiment with that caliber in ways unavailable when shooting it from a semi-auto.

Bullet shapes and weights can be fully explored in the M25, M625 and to a certain extent the M1917. Why wouldn't you do that? I mean, at least once.

If it is for convenience sake, I suppose I can understand. The thing is, you have a 'vette in your firearms lineup that you are driving 25mph everywhere. Not me!

Buy a heavy 45Colt bullet and do some experimenting.
