Cricket .25 shot string
Finally got a chance to run the Cricket .25 over a prochrono. I attached the results. I fill from a scuba tank so I only fill to 200 bar. I love this thing, shooting 3″ targets on a 2 liter from 100 yds was a lot of fun.

I cannot figure out how to do that…lol
Your getting a rise in velocity near the end of the string before it falls off of the regulator but its not real prnounced. If you change the scale on your point graph to show velocity only from 800 FPS to 1000 FPS this will be a lot clearer. Probably a slight regulator reduction or HST increase will flatten the curve and close the spread somewhat. It depends on what final velocity you are looking for. 😉

Doesn’t matter. 🙂 Your string starts at about 911 FPS and ends at about 930 FPS before it falls off of the regulator. If you turn the HST in slightly it will raise the beginning of the curve and flatten the curve and reduce the velocity spread. It wont take much so maybe 1/4 turn clockwise. It is pushing the entire curve up towards 930 so you may lose a few shots in count before it falls off of the reg since more shots are at a higher velocity. I have my .25 R3 Edgun set at 915 FPS which is great for hunting and still pretty accurate. The .25 seems to be able to handle a little more velocity and stay accurate IMO than say a .22. It is somewhat gun dependent but we have found the best range for .22 domed JSB pellets, generally, is maybe 870-900 FPS.
HST is an easy change but don’t turn it in too much or you may find the back side of the regulator and the velocity may actually drop. Just a little at a time. A regulator change is a bit bigger deal.
