I am looking for a load in my S&W 25 in .45 LC with 4 " barrel and 255gr BTB WFNPB. I tried 21.0 gr H4227 and got about 980 fps with it. Accuracy so-so and there seemed to be a lot of powder kernals around the throats and barrel area. Trying to keep pressures in the 23,000 cup or less range. Going to use this for close range deer/hog load per James Gates theory. Any suggestions within these parameters would be appreciated.
