Winchester WST will give about the same velocity with a 2.6 gr. charge under a 148 HBWC.
But, as others have suggested 2.7-2.8 grains of Bullseye will give very good accuracy. I tried HP-38 (which is the same as Winchester 231) and Bullseye was more accurate out of my revolvers.
Ahhh Bullseye. One of the oldest powders out there and still one of the best. Unfortunately, such light charges are used that a sloppy progressive press can cause some excitement at the firing range.
