I’m using pharmseller data for my 150 loads. I do have to seat my bullets deeper than he is. I did up my charge to 46.5 gr of biggame.
I think I'm going to have to try some of the Big Game as well. According to the Alliant data online, Hunter is a better powder choice at this weight, but I have Big Game...... I have been hunting with a 120 TTSX loaded with BG and it is great. 3180 fps at 1 grain under max.
