 I am new to the group, I have 3 300 Wby's and 2 of them like the loads I have worked up with H1000 but my new one doesn't seem to like it so going to try different powder, if anyone has any info on the IMR 7977 I would appreciate it.

I'll be following along here as well. I'd like to see this powder in QuickLoad so I can simulate it in both 270 & 300Wby.

I've had good luck with 4955 in that line and the 300bee.
