blazarwolf Posted October 2, 2008 Share Posted October 2, 2008 I could probably come up with something close to true, but for the smartys out there... Can anyone explain why a bullets spin adds accuracy? In good words and not mathmatics please. Link to comment Share on other sites More sharing options...
kevinalm Posted October 2, 2008 Share Posted October 2, 2008 First and formost, it prevents the bullet from tumbling end over end. Tumbling causes the point of impact to be more randomized. Kind of like a falling leaf fluttering to and frow as it falls. Also, the axial spin along the line of travel evens out the effect of any surface imperfections, further reducing the 'falling leaf' effect.

ecoli Posted October 2, 2008 Share Posted October 2, 2008 you can see the effect for yourself at lower speeds. Throw a football with and without spin and see which throw is more accurate and farther. Link to comment Share on other sites More sharing options...
big314mp Posted October 2, 2008 Share Posted October 2, 2008 you can see the effect for yourself at lower speeds. Throw a football with and without spin and see which throw is more accurate and farther. Well, this shows that it does happen. But why? Is it really only the prevention of tumbling that kevinalm suggested? Link to comment Share on other sites More sharing options...
insane_alien Posted October 2, 2008 Share Posted October 2, 2008 pretty much, bullets preferentially fall on their sides but if they are spin stabilised they will go point first. this decreases drag and stops it swerving off to the side. Link to comment Share on other sites More sharing options...
Externet Posted October 2, 2008 Share Posted October 2, 2008 ...And I thought it was related to gyroscopic effect, as to keep the axis aligned:-( Link to comment Share on other sites More sharing options...
swansont Posted October 2, 2008 Share Posted October 2, 2008 ...And I thought it was related to gyroscopic effect, as to keep the axis aligned:-( It is. Conservation of angular momentum. Link to comment Share on other sites More sharing options...

Mr Skeptic Posted October 3, 2008 Share Posted October 3, 2008 It also prevents imperfections in the bullet from pulling the bullet off course. With a spinning bullet, any imperfections will instead pull it in a nearly straight helix, rather than to one side like a curveball. Link to comment Share on other sites More sharing options...
blazarwolf Posted October 3, 2008 Author Share Posted October 3, 2008 So to summerize: It evens out structual imperfections of the bullet and minimizes atmospheric variables? P.S. does anyone recall some member having evil Spock as there avatar? (bearded devilish looking spock) If so i think ill have to go with socrates.

Cap'n Refsmmat Posted October 3, 2008 Share Posted October 3, 2008 And it gyroscopically stabilizes the bullet, keeping it from tumbling. Mr. Spock would be ajb, I think. He's around here somewhere. Link to comment Share on other sites More sharing options...
