I have used MRP for the past 25 years in two custom .340 Wea Mags with great results. MRP has been extremely accurate, very little deviation and near factory level velocities.
Recently on a discussion on another forum a member stated that absolutely, positively RL22 and MRP are exactly the same. You know how sensitive and opinionated some members can get so I did not respond. On this forum I have read several posts about MRP and RL22. One member here actually posted close up photos of the kernels of both powders showing obvious differences. I know they are both manufactured by the same company in Sweden.
I apologize in advance if you have already answered this question(s).
Are MRP and RL22 exactly the same powder with just different labels?
The MRP has never shown any temperature sensitive pressure issues having fired hundreds of rounds in 100+F and 10F temperatures with at least 8 different lot numbers over a 25 year period.
Are there differences in the treatments of the two powders to handle temperature sensitivity?
If they are the same powder have they always been the same?
Any other differences?
Thanks!
