I think it’s become my new favorite powder. As I’m loading several calibers with it, and having good luck.
Including 25-20, 32-20, 38-40, 44-40, 38-55, 375 Win. and 45-90.

I love it for my 45-70

Rx7 is a great powder for medium caliber, medium velocity rifle rounds. I discovered it years ago when developing loads for the 35 Remington. It does well in quite a few other rounds. When Hodgdon released the LeverEvolution powder I discovered it is suitable or a bit better for some of the cartridges Rx7 performs well in. Both are good alternatives to IMR3031 but sometimes you just gotta go retro!

I have never used it… still have 3 lbs of IMR 3031.

I’ll always keep some around, seems I have at least one cartridge that doesn’t have much use for the new kids on the block.

RL7 is bulky and serves well for mild velocity loads in the 45-70 case and its derivatives. It has become particularly useful now that 4759 is discontinued and 5744 is unavailable.
