When testing the 120gr Nosler BTs in the 280 Remington, I tried three different powders. Winchester 760, Hodgdon Superformance, and H4350. I have the loads and speeds for each, but H4350 was the fastest and produced the best accuracy. I'll need to find another use for Superformance.
Looks like I've boiled my 280 rem powders down to just two. H4350 for 120s through 154gr, and IMR-7828 SSC for 160s and heavier.
