You won't find any data, either. There's too little powder space to use something like H110/296 effectively. With a 230 grain round nose bullet seated to the maximum 1.275" COL, you could fill the space under the bullet 100% with H110/296 and still not make +P pressure. In addition, it will use up a lot of powder and what you use will burn so poorly it will leave fouling and gritty bits of unburned powder all over the place. You will get a great fireball, though.

I think you'll find Accurate #7 and Alliant Power Pistol are going to max out performance pretty much across the board (185-230 grain bullets) in the .45 Auto and Auto Rim at +P pressures.
