I am looking for recomendations for a powder for my 7mm/08 and 150 gr bullets (I have 350 of them I want to use up) I have imr4831, h414, varget, and some R-19. I bought the h414 specifically for the 7mm, but do not see many people following it. The varget (feed for the 22-250) seems to be for the lighter bullets, but not the heavier (145 and up). I would like to use the h414, but am somewhat worried about the sensitivity to temps (anyone have an idea how bad?) as I will develope hunting loads. Any comments are appreciated.
