My wife gave me a Garmin Xero C1 chronograph for Christmas. I was able to chronograph the Blazer Brass, Precision One Remanufactured, Super Vel Remanufactured, and Super Vel New (all 124 grain) today. The stated velocities in fps of these rounds are:
Blazer Brass: 1090
Precision One Remanufactured: 1044
Super Vel Remanufactured: 1050
Super Vel New: 1050
I shot 10 rounds of each using my 2022 CZ Accushadow 2 (4.89 inch barrel). The low, average, and high in fps for each one were:
Blazer Brass: 1091.0 1117.3 1135.8
Precision One Remanufactured: 1046.3 1075.8 1099.9
Super Vel Remanufactured: 1034.6 1068.6 1095.1
Super Vel New: 1035.8 1071.4 1085.4
No big surprises. The velocities were greater than advertised due to the barrel length. The Blazer was about 50 fps faster than the others and the Precision One was about 5 fps faster than the Super Vel. This all tracked with how the ammo felt when I shot it. The low, average, and high power factors were:
Blazer Brass: 135 138 140
Precision One Remanufactured: 129 133 136
Super Vel Remanufactured: 128 132 135
Super Vel New: 128 132 134
Even the lowest velocity of the 10 shots for all of the ammo met the 125 power factor USPSA minimum, so any of these would be acceptable for USPSA.
