Re: which powder is remington using in 7 rm ??
I can't tell ya what powder they're using in their factory loads. But if ya need any load data just ask. Some of the best powders I have found are RL 22, IMR 4831, H 4831, and H 4831sc.
Best of luck to ya.
I shoot 1/4 inch groups at a 1000 yards. That is...till my second shot.
