I was recently comparing the accuracy/precision of the RMR 75 grain hpbt to SMK 77\’s for a 600 yard load. All shooting was from a bench at 100 yards in a zero wind range, rifle fully rested front and rear. 10-shot groups. Rifle is an off the shelf 20\”, A2 govt profile, chrome-lined barrel, 1:7 twist (not exactly a \”match\” barrel).
Anyway, the load was 23.5 grs of H4895, c.o.a.l. was l-o-n-g at 2.380\” (for slow-fire, single-loaded string in xtc matches). Don\’t have a chrono so velocity is any body\’s guess.
BOTH, the RMR 75\’s and SMK 77\’s had the exact same extreme spread of 1.38\” (1.32 moa). The mean radius of the RMR was .61\” (.59 moa). The mr of the SMK was .5\” (.48 moa), but only because 2 rounds were touching. As stated, the es was exactly the same with both bullets, soooooo, I\’m a firm believer in the RMR 75\’s.
I\’d post pics of the targets if I knew how to do it.
Hope this helps you out some.
