MRP is about the same burn range as RL-22. Some say it’s a better refined version.
My Swede sure likes it with 139 Scenars.

I tried some 7828 in mine and it loved it. It also shoots several other powders ok. Speer data would indicate you're leaving a few hundred fps on the table with that one. Did you clock it? DF I wonder why the low velocity with 7828??? Most pf the data I've seen for other cartridge show it close to RL-22. In fact, when I was looking for RL-22 for my .280, none was on the shelf at the LGS. Checking in a couple of manuals showed velocity to be very close to RL-22 so I used that. My .280 didn't like it. I got the speed but no accuracy. Strange that Speer has it so low over the velocity lever. I wonder why???? Paul B.

I've noticed that my Speer manual(#14) is pretty conservative on velocities for most of the rounds that I load.

Ramshot Hunter has worked really nicely for me in the Roberts from 90s-115s.

I used IMR4350 with 115gr partitions or any 117gr bullets load was 43.5gr in my 760 Remington pump. Velocity was about 2925 FPS.

I could live with that.

The best powder I have found is RL23 which is a improved version of RL22, it is temperature insensitive and provides the same speed.
