Vulcan .25 Chrono Results (2nd Chrono at 920 fps)

Hmm, I tried turning my hst in because mine was acting like yours, but the velocity would not climb above about 907 and was inconsistent. I turned it back and shot a string of 30 shots before it fell off the regulator and got a high of 903, low 896, ES=7. Ave=899, sd=1.

so I'm happy with that. It also dropped off after it fell off the reg, so I guess that's where my gun is going to be happy. Poi stayed mostly consistent at 40 yards while I was shooting. It's pretty windy today, so the poi wandered a bit, but I attribute that to the wind.
