Abstract:
A bullet with grooves to create more surface area to reduce drag, thus keeping a flatter trajectory that reduces the effects of wind, temperature, elevation and angle. Groves would be manufactured into the bullet and bullet jacket twist would need to match the barrel twist. For example, 1 in 8 twist, 1 in 8½ twist, 1 in 9 twist, 1 in 10 twist, 1 in 11 twist etc. Groves would be over the ogive of the bullet prior to where the bullet contacts the barrel wall.
