I have loaded many RMR FP Match Winners. all bullet weights 115, 124, 135, and 147s. Reloading is a passion of mine so is bullseye shooting and I specialize in 9 mm. I have chronograph data for nine different gunpowder’s suited for 9 mm. All of them do at least one thing very well, some of them do many things very well. So here goes my best data and my safest data for 124 grain RMR-FP.
Silhouette 5.4 (124FP 1.10 OAL 1085 FPS )
Silhouette 6.0 (124 FP 1.10 OAL 1230 FPS )
Silhouette 6.2 (124 FP 1.10 OAL 1260 FPS)
Silhouette consistently adds 15 FPS per one tenth of a grain you can go as low as 4.8 grains and still cycle most slides. I have been higher than 6.2 grains with Silhouette but I will leave that for another time.
