I already posted where you could find it. Do a search for Texas Ammo (I think is the name of the outfit) Clark custom guns (460 Rowland, load it down a bit for Super) and Ace Custom Guns (originator of the .45 Super. I asked you what bullets you want to use, if you have a fully supported barrel, what powders you have, and what velocities you want. 10. 0 grs of Unique gets a 165 gr swc to 1400 fps.
