Wow! love the ships with tubular sails!
I never realised just how much affect it had on an object and the way it accellerates as it goes further!
I read up on this after I experienced it a few years ago, I had been shooting .177 JSB heavies in a BSA barrel for some while and decided to try a faster twist rate. I installed a Steyr barley twist barrel which measured at 15.5" twist compared to the 19" bsa. The heavies were stunningly accurate in normal conditions but when the wind exceeded 10mph it had a weird effect, with a stiff wind from the left the pellet moved right but also lifted up, a stiff wind from the right moved the pellet left and down. The pellets dropped more than they rose as gravity was either assisting or fightting the movement resulting in too many variables!! I didn't stick with that pellet barrel combination!
Far out ! Not even 1st of April , gonna have to look into this
??! Idiot ??? ??? ? ? ??! ?
The Magnus effect,.......has Zero effect on diablo shaped airgun pellets,.....now if you were shooting round lead ball with a hop up ( as in airsoft ) then you would see an effect.
To put it very simply an air rifle pellet spins. But to try and impart the magnus effect it would have to tumble end over end, but that could not ever work.
Paula, didn't realise you had a crush on Magnus Magnuson , no wonder you make Dave wear those shirts to make him look 75 years old.
Which is why it only occurs when the wind is from the side, perpendicular to the rotational axis., exactly the same as the back spun basketball.
Thats why i make him dye his hair Gray
The wind isn't from the side of the pellet, its head on except for very very small time after it leaves the barrel. The shuttle cock shape makes it always align with the overall wind vector. Hence magnus effect unlikely.
