Tuning Chronograph tells the tale

I received the light bars for my Competition Electronics digital link chrono today. Ran 10 RWS 7.0grain pellets through the Pardini K12 at 140bar. Pellets all in the black.🥳
Extreme Spread of 4 FPS, Standard Deviation of 1 FPS.
Average Velocity 10 Meters from the muzzle was 544 FPS.

Second set of 10 RWS 7.0grain pellets at 75bar. Pellets all over the 10M target, in the White 🤬,with some key holing near the bottom of the target. Extreme Spread of 48 FPS, Standard Deviation of 15 FPS.
Average Velocity 10Meters from the muzzle was 153 FPS.

I think I will start changing out Air Cylinders at 100bar from now on, and see if that pressure will allow the K12 to maintain enough velocity to clean the target. 🎯

The chronograph wouldn’t read the pellets until I hooked up the two light bars, made for indoor velocity readings.
