Sierra Reloading Data Book (7th Edition) shows the following for 125g FMJ & JHP:
Titegroup: 1000fps/3.7gr, 1059fps/3.9gr, 1100fps/4.2gr, 1150fps/4.4gr (max load).
I don't like them. One of three I bought has a spring that failed - will not spring back and feed rounds. They "swell" when loaded and will not drop free. Two of the three will not lock the slide back when empty. Better mags are available.
