[QUOTE="MontanaRifleman, post: 777090, member: 11717"] Someone is misunderstanding someone.... Spins = RPM's How fast a bullet spins is dependent on twist rate and muzzle velocity only, not barrel length.... which isn't the question I'm asking. Tighter twist puts more resistance on a bullet and it will increase pressure and reduce velocity, or reduce velocity with the same pressure. The max load muzzle velocity for bullet coming out of a 9 twist is going to be slower than the max load velocity of the same bullet coming out of a 10 twist. [/QUOTE]
