    Ballistic trajectory and rifled barrels

    Any ballistics experts out there? I have been wrestling with a thought experiment for some while without success. The purpose of rifling is to impart spin to a projectile, which gives it gyroscopic stability. My interpretation of that is that as soon as it leaves the barrel it will carry on...

    What's the longest possible spin-stablized projectile, and why?

    I've been looking into extreme-distance shooting and calibers lately, .408 Chey Tac, .338 Lapua, .50 BMG and the like, and it occurs to me that the ballistic coefficient of the projectiles is quite important. At the distance of a mere kilometer, a .600 BC .50 BMG bullet will have lost half of...
