I recently developed a good load with a 160 Accubond and 74gr IMR 8133 for a friend. His Christensen Ridgeline shot 3125fps and about 1/2 MOA. My 26" Remingotn 700 shot 3160fps, although I didn't shoot any groups, though I should have. I read a few people say it didn't give the best accuracy, but my one and only experience was very good with this powder. Trying to get a broader idea of how this powder does in this cartridge. Has anyone else tried IMR 8133 in the 7mm Rem Mag? What were your results?

Not in the 7mm mag but.....

I was planning to try it next, but the accuracy I got from 7977 was so good I stopped right there.

8133 transformed my 264wm from good to AWESOME.. I am a fan.

I use 7 mag brass so that qualifies me to answer..
