Well I just looked up the Lee Loader and see that it's a stand alone product and doesn't use dies so disregard my last post, it ain't going to help, sorry.
I use Lee dies for .455 on my Lee turret press with no issues what's so ever. If you look close one of the dies is labelled .45colt> I will take a look and post which one.
I've used a Lee hand press and a set of .455 Lee dies for years and no brass damage whatsoever. It's a bit bigger than the Lee loader box but not hugely. Easily available. I was at the Ancaster gun show this morning and there was both a hand press and .455 dies. Coulda had both for a few dollars under $100. My 2 cents.
You may need a separate expander plug.
Track of the Wolf has expander plugs or if you have a lath you or a friend can make one.
I use two expander plugs when reloading .44-40, it sure makes it a lot easier.
