These are some sad shot strings if you ask me. The POI suffered along with the deviation in velocity. We also had several double shots, or double taps. All shot with JSB Kings 25.4 gr. No jamming issues. All semi auto mode. Shot over a Pro Chrono Digital

I have no clue how to fix this velocity spread. Looks like me an Max are on a short term relationship. Due to the following reasons:

Heavy
Will only shoot JSB kings
Approx 25 double taps in 500 rounds so far
Extremely loud
Not as accurate as I had hoped, Prod was more accurate to 40 yards.
Does not get 40 useable shots as advertised.
Full auto un useable
Extreme spread is just not acceptable, wild velocity changes
Forgot to include that the pistol grip does not fit my hand very well.

No joy in Maxville at the moment.
