I'm working up PG loads for my hunting bud's 7RM; he's headed to Africa later this year. I have 160 NAB and 160 TBT bullets to try, hoping RL-26 will work. I do have Mag Pro, Retumbo, H-1000, 7828 and the usual candidates. My 7RM works great with RL-22 and 140's, have a big jug of MRP, which some claim is a higher quality RL-22, which I also have along with RL-23.
*** I don't like to get caught short when reloading...
