[QUOTE="mitch260, post: 978924, member: 53720"] Variations from barrel to barrel will have a greater effect on velocity than a one inch difference in twist rate. A bullet leaves the barrel with only so much energy, by spinning the bullet faster you rob a few foot pounds of muzzle energy that are converted into rotational energy. When you run the calculations of how many FPS those few foot pounds are worth, it comes out to an insignificant value. You gain far more in stability capability's than the few FPS you lose. As mentioned its in Bryan Litz's Book. [/QUOTE]
