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.
