Consideration for Tuning Output:
It is the owners responsibility to assure legality of their air gun power output.
Vortek’s Location of testing is 578 Feet.Above.Sea.Level. (F.A.S.L)
For every 1000ft above or below will be approximately .029 difference in velocity, thus foot pound (Ft/lb, Joules) of shooting energy.
1000 F.A.S.L.x .029 = 29fps approx.
Joules= .7475=ft/lb
Easy, do-it-yourself with virtually no pre-load force on assembly.
