I went to the gun store today to buy components for my 45 colt single action reproduction. I bought primers, cases and 400 rounds of 255 sw. My problem is, I can't fine any loads for that bullet weight. Ken Waters has a few loads, but I don't have any of those powders. None of my manuals have loads for 255gr. bullets. My two powders are Unique and W-296. Anyone have a load for 800-950fps with either of these powders? Or sugest a better powder? OOBuckshot
