    I have loaded and shot thousands of rounds of RMR 124 FMJ FN, aka Matchwinner.

    3.8gr Titegroup, COAL 1.075. Feeds and shoots in all of my 9mm pistols including the short throat CZ. 1048 fps average muzzle velocity from Sig P226 9mm 4.4″ barrel. Titegroup has a very quick pressure pulse but this load is quite smooth for good all around shooting. 100% powder burn.

    Hodgdon Longshot 5.5gr, yields a powerful 1160fps, COAL 1.075″.

    For a real punch Power Pistol 6.2 gr, COAL 1.075″ yields 1226fps. The felt recoil pulse is really solid and QuickLoad puts the chamber pressure near max so be careful and have a solid gun for this. COAL lengthened to 1.100″ reduces chamber pressure prediction to a more reasonable but high level, or reduce the powder charge. Only about 85% of powder is burnt in 4.4 inches.

    The 3.8gr Titegroup, COAL 1.075 is just a great and safe everyday load IMO.

    4.2 gr Titegroup, COAL 1.115.

    Have shot many of these in a VP9, VP9SK and CZ75 action. No pressure signs on brass, no extraction issues. Keeps good accuracy at 50 yards. Also works great for bowling pin matches with the MPR head.

    I also use 4.2gr TG, loaded to about 1.106. No pressure signs or other such issues. A little hotter than I think is strictly necessary, but keeps me in power factor for competition.

    I use these bullets(124 fmj fn) with 4.7gr of be-86 loaded to 1.100. No issues and excellent accuracy.
