[QUOTE="cohunt, post: 1660889, member: 94491"] technically they are not cannelure groves-- here is the difference between drive band, and grooved bullets : [B]Drive Band Bullet:[/B] A bullet where the shaft of the bullet conforms to the land diameter of the barrel and should be in contact with the faces of the lands. The drive band diameter of the bullet conforms to the groove diameter of the barrel and should seal the barrel against gas blowing past the bullet. The total width of the drive bands must be less than 50% of the length of the engraved section of the bullet where bullet material is displaced. Displaced material volume is less than 50% of the volume of material that would be displaced, if the bullet had no drive bands. [B]Grooved Bullet:[/B] A bullet where the shaft diameter of the bullet is in relationship to the groove diameter of the barrel. The shaft of the bullet may be under size and may not seal the barrel against gas blowing past the bullet. The depth to which grooves are cut into the shaft of the bullet, do not conform to the land diameter of the barrel and are deeper than the land standoff of the barrel is high. The total length where bullet material is displaced, is more than 50% of the length of the bullet shaft that is in contact with the barrel. [/QUOTE]
