In my USP45, I like to use a 200 gr SWC. There are two kinds I use Carroll's LSWC for about $44/1K in my local store, and Rainier plated SWC for $80/1K through Midway. I use 4.9 gr of IMR Hi-Skor 700X for a light target up to 5.3 gr for a heavier target. Approximately the same powder charge under the Rainier bullet works well also.
