The RMR 69s are a real bargain.

I've tried them and they are almost as accurate as the 69 SMKs. Given the cost difference, they are well worth trying.
At 100 yards, my 5-round group averages using my 12 FV with both SMK and RMR 69 gr bullets are pretty close.
RMR 69s averaged 0.300 with three different powders for 35 groups. They shot best with Varget, 0.286 for 8 groups. The other two averages were .309 and .324.
SMK 69s averaged 0.279 with four different powders for 202 groups. They shot best with Varget, 0.249 for 44 groups. N540 averaged 0.251 for 41 groups. The other two averages were 0.286 and 0.291.

The RMRs are a great bargain, but I am an accuracy nut and am still partial to the 69 SMKs, especially with those two powders.
