[QUOTE="MudRunner2005, post: 1364427, member: 12995"] Progressive twists are designed to help alleviate initial pressure spikes and increase velocity, by giving you lower pressures at the initial bullet travel with a slower twist. Then as the pressures build as the bullet is traveling, increasing the bullet's velocity, the twist rate also starts tightening up, increasing the bullet's RPM's in the bore, and as the bullet exits the muzzle it is now spinning fast enough to be stabilized. I think it's a really cool concept, based on scientific principles, but I've never shot or owned one, so I cannot confirm or deny how well they work. [/QUOTE]
