What are you guys using? Does anyone have load data for IMR 7977?

I use 67 grs. of H-1000 with a 150 gr. partition. 3052 f.p.s. I had pressure signs with any faster powder.

smokepole,

So far, with a couple of different lots of 7977, I've found it just slightly faster burning than H1000. Have used H1000 starting charges to work up loads with no problems.

Thanks MD and 'Cocker. Those two are on my list.

H4831, RL22, H1000, WW780 all work well.

RL17. What bullet?

H4831SC, H1000 and my favorite so far H4350. Have some H100v and just for giggles some RL17.

Scenar.
