Does anyone have any load data for the new temperature stable IMR 4955 for .375 H&H and larger cartridges?
450 Rigby with 550 grain ...but I totally agree... having that powder sit there and not have a suitable rifle to use it ...is terrible. The 450 Rigby needs its sibling!Thanks Dr. Bob,
Hodgdon lists IMR 4955 loads for 416 Rigby and 500 Nitro, neither of which I have guns for.
I have .375 H&H, .416 Rem, .416 Taylor, .458 Lott, and a .450 Rigby. 8 lbs of 4955 followed me home yesterday because the price was far to good. Maybe I need another rifle to go with this powder!
