Chronograph: Caldwell Ballistic Precision Chronograph G2. Five shot velocity average: 949, 890fps Gel Temperature 70 degrees. Out of the Sig P229, the five shot average velocity was 949fps with a high of 964fps and a low of 921fps.

Round two had a velocity of 931fps, expanded to .52 inches with a penetration of 20.25 inches and a recovered weight of 180.2 grains. 
In the heavy clothing covered gel, the first round had a velocity of 932fps and penetrated to 26 inches with no expansion. Recovered weight was 180.3 grains. Number two also had no expansion and penetrated to 27.25 inches. Velocity was 938 fps and weight was 180.1 grains.
