Hello, if i shoot a 6mm 0.3g bb down my 300mm barrel at 350 fps what is the maximum topspin i can give to the bb to make it touch the ground 50m away, if i shoot my gun at a 45° angle? Is the bb gonna immediately touch the ground as soon as it go out of the barrel due to the magnus effect? Or will the air gonna push it at list 10 15 metters away and ill be able to go to 40 50 metters aiming higher? Is it possible to give my bb trajectory a nice curve if i give it the proper amount of topsin? Intuitivly i want to say yes but airsoft forum tell me that even if i aim high its just gonna go down immediately. Anyway thanks if you can help.
