I've searched the net and thru all my reloading manuals but there are no loads listed for Winchester 296 and the 45 Colt. If anybody know of a source for that info please let me know.
I compiled the following a while back for my own use from what I consider to be fairly reliable internet sources. The assumption in putting this together was Ruger/FA/Contender, not colt/clone/S&W.
I believe the rumor that H110/WW296 are the same thing and use the same load data for both.
I've also found the Paco Kelly article on 45 in leverguns useful. Steve's Pages has useful charge ranges for various powders across a huge range of cartridges but, in my opinion, he doesn't draw a very clear line between Ruger/FA/Contender data and Colt/clone/S&W data in the 45 colt cartridge.
Use the follow at your own risk. You'd be insane not to check something you got off the internet against a couple of sources published by the bullet/powder manufacturers.

"As you can see I like the 9.3 grain of unique load. I have a couple little dandy powder measures and one is always set up with that rotor in it. It works good for the .41 44 mag 45 colt and even the .475 and .500 for a good lighter load and almost without exception shoots a little better then the standard 10 grain load.
I use mostly fed std primers for everything but 110 then I switch to cci 350s..."
