[QUOTE="taly01, post: 1625973, member: 28443"] The idea of overspinning a bullet was explained to me as in throwing a football with spin, too much spin it will not follow the trajectory on the downwards path on its axis, but be pointed up a bit in the same orientation as it left the barrel. So this is why the long range overspun bullet gets a bit weird, mostly trajectory is a bit off as the BC of the bullet changes as its travelling nose up *minutely* off axis. Hope that makes sense.
