I've used it quite a bit over the past 8 years. It's burning rate is similiar to Rel 22, but is "NOT" the same powder as some will claim. It's given me good to great performance in a number of rounds...6mm Rem, .250 Savage AI, .257R, .280 Rem and 7x61 S&H.

JKuczmarski is correct.
Norma MRP is the same as RL-25 -- both of which are made on the same production line in Bofors Sweden.
There is variation between the two, but no more than between lots of powder. Reduce at least 10% and work up if you have data from one and are reloading the other.
