I wanted the RMR to approximate them, so I loaded the same charge of CFE223. I will mostly shoot them at 3gun at a local club where there is a 200yd range they typically use every other month, sometimes with some pesky-small plates. Initially I plan to load up at least one mag of SMK in the case that we get there and the 200yd range is setup, since those will be the load the gun is most precisely zeroed for, and load my other mags with the RMRs. If the RMRs do well enough I will probably just save all of the SMKs for a rainy day.
My calculation is that I can load the RMRs in once-fired range brass I bought for about what 55gn steel case ammo currently costs.
