Update, FYI: After doing a long-overdue trigger job on my 4" 10-8, I decided to run a few rounds of this ammo over the chrono Saturday.
Temp: Approx. 70 deg. F
RH: Approx. 90%
For three rounds: Mean vel.: 1063.9 fps.
H: 1090.7
L: 1035.7
ES: 55.0
KE: 370 ft.lbs.

This particular gun has a tight barrel/cylinder gap, and runs fast. It got an average of 943 fps. with FBI loads from the same box that got 771 from the Magnum Carry.
Thanks for the real world info. I had been meaning to chrono these from
my 4" Model 28. I feel confident carrying these rounds-they are at least as good as most 9mm rounds and probably better.
