[QUOTE="WildRose, post: 1496120, member: 30902"] It will become much more pronounced with faster twists but in the ranges we're working within more than 20fps doesn't seem reasonable. The tighter the twist the more friction which is why gain twist barrels are so hard on bullets. With them you're literally cutting new grooves the full length of the barrel but you can get insane velocities that can't be achieved with a standard twist due to the bullet getting such a run up before it tightens.
