Not MD, but are they exact? No. They are kissing cousins so close to each other that it’s my belief that RL22 is actually MRP seconds or blemish whatever you want to call it. I’ve interchanged 22 and MRP in a 25.06 for many years.charge weights are nearly identical, performance is also nearly identical. Where it varies is consistency lot to lot.
Agree with you 100%.
When the run of Re 22 is made the reject box has less powder in it
