I use Ramshot SILHOUETTE for jacketed bullets in .45 ACP. With 200 gr. SWCs I use WST. I load the 185 gr. Golden Saber and get good accuracy with Silhouette and I can get +P velocity without +P pressure. My new quest is with the ZERO 230 gr. JHP and Silhouette. THis combination will get to 1000 FPS in a standard load. The ZERO bullet is a beautiful thing. Looks like a Remington but the price is much better. A rounded Ogive rather than truncated. Sierra says that 7.5 is max charge of SILHOUETTE with a 230 gr. bullet. Ramshot says that 7.3 gr. is a start charge. Both agree that 7.5 grs. is good for 900 fps from a 5" barrel. My XDm has a barrel length of 4.58" so I'm estimating 875 FPS from my pistol, or a factory duplication load. Silhouette is also treated for flash, so these loads should be quiet in the dark. I will shoot rested and unrested groups at 50' and I expect better than combat accuracy.
