I read lots of reasons to use Reloder 22 for heavy .243
Any reason not to? My barrel should be ready in a couple weeks. I have some 107gr Sierras and RE22 on hand, is there another powder I should look at?
Anyone using 4000MR?
Trying to run about 2950 fps, but I need temp stability so I don't end up disqualified on a hot match day.
