IMR 7977 for 7mm RM

[willtim]

I was at Cabelas today and they had one bottle of IMR 7977. The bottle said good for 7mm RM so I bought it (powder very hard to come by here). Anybody have a good load for 175 grain Partition? Thanks

Tim, 7977 is very close to H1000 on the burn rate chart. Hodgdon website has load data for this powder.

Wilitim, because H1000 is scarce and most shooters develop a load and stick with it. (No matter what). I changed to 7977 in my 7mm Mag and love it. I shoot 168 Bergers within a grain of what I used to shoot H1000. I now own enough 7977 to "shoot out" two barrels.
