I recently started reloading, and after much research and reading articles from John Linebaugh and Papa Elmer I have decided to load a 265 gr. Keith bullet for my Ruger Blackhawk with a 4 5/8" barrel and my Winchester M94 Trapper with an 18" barrel. Both are chambered in 45 Colt. My problem is I don't have any reloading data for this bullet. I have looked all over the internet, e-mailed powder manufacturers and companies such as Lyman, but nobody has anything they're willing to share. I'm using Green Dot and WSF powders right now, but I'm not afraid to change if necessary. Any help would be greatly appreciated, thanks in advance.
