I am a fan of IMR7828 175grn sp, start at 60.0grn mag primer max is 63.0 grn
150 grn sp and ETIPs start 65.0 grn mag primer max is 69.0 grn For hunting I prefere 67.0 grn 7828 150 grn Etip 30 tho the lands 3090 to 3115fps, deadly on white tail and moose
I have had good luck and vel with RL22 in 150, 162 & 175 grn sp but there are a lot more hens teeth around here than any alliant powder
I also use 145 grn btsp's at 69grn IMR7828 and 47.0 grn IMR3031 but that bullet is a little light for my liking and using the IMR3031 is a little too fast for such a large case capicty (but in a pinch it works)
