I am thinking of developing a load for my.45 revolvers(625's) that will be using a 255gr. SWC and Longshot with a velocity of about 900-950 fps. I have a bunch of it and have had good success with it in other applications. I have been using 13.5 grs. of 2400 with this 255gr. boolit for a field load, it is accurate, but a bit more power than I need, and less of the Longshot would be more economical as well. I have shot a load using 7 grs. but have not chronographed it. I already have an accurate lighter load using the Lyman 200 gr. and 231. Has anyone here experimented with this powder for this application?
