I started using MRP in 7mm Weatherby just wanting to try other powders and found that it produced excellent consistency in velocity and accuracy before I was aware of the RL22 kinship. 72.0 gr of MRP behind a 150 TTSX gets the job done! I have several pounds from the same lot # so I’m not working up other loads with it out of conservation. I put my .300 Weatherby on a RL26 diet. Happy Trails
