Ive got a rough factory tune done but what velocity should i be aiming for with JSB jumbo diabolo 15.89 grain? sniper 700mm im running 140 1st reg 75 second reg theres so much different info it was getting a bit confusing.
that's a shame, i have my own webserver i would have liked to have taken it on for him. was it a place to add your own tune? i might look at a program to do the same.
