im interested in seeing how well your gun shoots, and see what the relation between velocity and rate of twist is, and see just how much a fast twist improves the flight of a high velocity slug. sooooo, if you could tell me the gun you use, your average group size at 50 or 100 yards (preferably 100), and the slug ammo you use, and the rate of twist your barrel has (if you dont know please still post, i can figure it out if you tell me what gun you use), i would really appreciate it! thanks!
