Re: 7 MM RM and IMR 7828 HELP
7828 will work well in a 7rem if you are shooting 150 grain or heavier pills. I shot sierra 140's with it for a while, but the last 7rem got unstable accuracy wise with it in cold temps(below 50 or so and the accuracy went fron 1/2 moa to 2 to 3 moa). The same rifle shoots the 150 nos bt's with 7828 to 1/2 moa all the time no matter the temp.. It's a boring gun, but it works.Rl22 works well in my rem, but I'm saving it for my 300 win and 7stw. I've been burning 4064 in this rifle with 140's- 3100 fps and acceptable accuracy at all temps.(I've got a lot of 140's- they gotta go somewhere).
