Would like to Use Unique powder to load my SRH 44 mag using Cast Perf. 255 Gr. WFN PB to about 1150 - 1250 FPS. Any thoughts on what load to use. I was thinking about 10 grains and Rem 2.5 Lp and/or CCI 300 LP primers. Loaded many 240 and 300 grain XTP's with H-110. I also have H-110, Herco, Longshot, and Green Dot on hand. Going to be used for whitetail in Michigan. Thanks.
