RE7 is a lot shorter than IMR 3031. With out looking and going by memory, it is near IMR 4198 in granule size. I consider them cousins in burn rate but I always get a little higher velocities with RE7......some of my arms like IMR 4198 and some like RE 7.

I always go with the accurate loading and velocity is what I consider second place.
