[QUOTE="MagnumManiac, post: 2410473, member: 10755"] My best accuracy comes from 4 and 3 groove barrels. Whether this makes any difference to a Hammer I do not know. Another aspect is the rifling profile, skinny lands engrave less of the shank and are often faster in velocity than wide lands. Ballard rifling, equidistant lands and grooves, engrave the most bullet shank and distort the bullet the most. Fired bullets look hexagonal if looked at from the base. You want the least amount of distortion for accuracy. The amount of grooves and their size makes almost zero difference to how a bullet spins upon release in my experience, flight thereafter is another matter. Cheers. [/QUOTE]
