Bullet: RMR 124gr RNFMJ
Primer: CCI-500
Case: Mixed
Powder: Winchester 231
COAL: 1.150″
Kahr CM-9 Chrono Data (3″ barrel):
Ambient Temp. 72F
Charge Wt. Measured Velocity
4.2 903 fps
4.4 950 fps
4.6 981 fps
4.8 1008 fps
5 1041 fps (hot load)

Springfield Hellcat Chrono Data (3″ barrel):
Ambient Temp. 78F
Charge Wt. Measured Velocity
5.0 1126 fps (hot load)

Caution: The 5.0 gr. load is hot but reliable in two specific guns I’ve tested them in. I have not seen any pressure warning signs in my guns, but for reference, my +P Federal 124gr factory ammo measured 1030fps out of my CM9.

Note: The Hellcat seems to have a tighter chamber than the CM-9. That plus the slightly warmer conditions might possibly explain the higher velocity.

I’ve tried a few in my 3.6″ Kahr CW9…

RP cases, CCI500 primers, all seated to 1.135″

5.6grn Unique, 1050fps
4.5grn W244, 1000fps (excellent accuracy…)
5.5grn BE-86, 1050fps.

I’ve got a bunch of TiteGroup to burn up, so that will be next.

twoodruff78, thanks for sharing the W231 chronos… my MagnetoSpeed is for my rifles… I’m using W244 and limited the COAL to 1.063 because of my most restrictive pistol. Can tell they’re down on power, but still accurate as hell… 4.2 to 4.4 grains… the rest of the mutli rounds and now the round nose I’m going longer… the other two 9mm’s are “normal” plus just picked up a Stribog that I’ll need to feed. Your numbers sure help give me an idea where mine are at. Thanks!

4.2 gr. Sport Pistol CCI 500, 1.135 COAL

1070 fps avg. Walther PPQ 5M, M&P Pro 5″
1080 Springfield 1911 RO (5″bbl)
1060 M&P CORE 4.25 bbl
1040 M&P 4″ compact, CZ 75 compact 3.7bbl
All the above velocities meet the 125 min power factor for IDPA and USPSA . They also feed and run flawless and are extremely accurate.
