Does anyone use IMR 7977 for a 7mm Rem Mag? I'm looking to load 160 grain Accubonds. I've fooled around with this powder a bit with 140 grain bullets, but none of the variations grouped, and I ended up finding a sweet load for the 140s with 4350, so I quit messing with it. I'm thinking the 7977 might do better with the heavier bullet, I'm curious if anyone has some words of wisdom to add.
