[QUOTE="Dragoon300, post: 2527824, member: 115285"] No, the projectile length to diameter is the primary factor. The bore rider design reduces friction, especially on longer projectiles. They are often used in conjunction with gain twist rifling to help get heavier projectiles turning easier. Like in the 20 mm Vulcan with the projectile posted above, the rifling starts pretty much straight at the beginning and ends up twisted like a cork screw to spin it fast enough to stabilize. The bore rider also gets the projectile aligned in the bore prior to firing, unlike standard bullets. [/QUOTE]
