Tested 3rd June 2025
3500psi fill
50 shots per fill
pellets: jsb 18.13g
velocity with jsb 18.13g 840fps
solvent through the barrel, 3500 psi fill, 50 pellets with satisfactory 5 shot groupings using JSB 18.13g resulted in grouping at 25 yards resembling a clover leaf, air remaining 1500psi which leads me to believe the internal preset regulator is set to 1500psi
