Good thread!
What do you have on available 10mm and .45 loads?
.45 is an interesting cartridge to use for hollow-points. Loads often don't have much more energy than a .40 or 9mm, but they do often have considerably more momentum...like...50% more. The increase in momentum as you go from light/fast of 9, to meh/meh of .40 to heavy/slow of .45 means that as you go up in caliber, you'll experience less deflection. Let me show you an example of what I mean in real numbers...
Federal HST 124+p 9mm out of a glock 19:
Velocity: 1178
Energy: 382
Momentum: 20
Federal HST 230+p 45acp out of a colt 1911:
Velocity: 957(smokin fast with this heavy of a .45)
Energy: 467
momentum: 31
and in real world deflection...

Notice that even though the .45 only has a ~20% increase in energy, there's over 50% increase in momentum. It should also be noted that the larger surface area of the base of a .45 compared to a 9mm makes any increase in PSI behind it much more efficient in transferring energy to the bullet. It's the reason why shotguns are so efficient...more base for that pressure to push on.
Now thinking in terms of energy available to do work...work being the tissue moved or crushed by the bullet...since the .45 has pretty similar energy when compared to a 9 or 40, it'll do roughly similar work. Given that the .45 will expand larger than a 9mm most of the time, it means that it will do that work in a shorter distance...orrr...that it won't penetrate as deep.
It's very difficult to make a .45 that will expand to 1.5 times it's diameter and penetrate 12-16" in gel because of what I stated above. Pretty much the only way to do it is with a +p loading or in something heavy for caliber. With the exception of the dpx line, 185 gr .45's will just not reliably penetrate. The best loads are often the 230 gr loads such as the 230 gr.45hst+p above.
here's an example of what I'm saying with 185 gr and penetration...

I haven't really seen any independent testing, but have reviewed hornady's testing of their new 220 gr +p critical duty and am pretty interested in giving it a hard look. Their other critical duty lines in 9 and 40 don't really expand all that huge, but penetrate great to around 15". I think this bullet design lends itself very well to the .45.

remington golden sabers still have issues with core/jacket separation, unless you get the bonded bullet. They do feed great in most things though, so could be an option for 1911 shooters who's guns won't feed other hollowpoints.
