I tested some out with Titegroup last fall. COL of 1.060″, shot out of a 3.75″ barrel from a CZ P-07.
Charge    Velocity    STD    ES
3.5gr          977.76        11.14    34.88
3.7gr          1009.07    8.85   25.79
3.9gr         1053.33    12.34   42.54
Not bad results, but I ended up choosing CFE Pistol, as I got a bit more velocity than I could from the TG without going over book max for my reference data. Same COL and gun as the TG data, and tested on the same day.
Charge    Velocity    STD    ES
