Ok guys. I am keeping details to a minimum here but it all boils down to this:

444 Marlin or 460 S&W?

All things in this scenario are equal other than the chambering. Same platform, same barrel length, nearly the same intended bullet weights. I do not have dies or brass for either at this time, but both are available to me for both cartridges for similar money. I stock 44 and 45 cal bullets for other firearms I have, so no gain either way there in way of component simplicity. Also, if it matters to anyone, I am not detoured by the fact that 444 cases must be lubed to be sized and 460 do not due to the carbide dies being available in the 460.

Near as I can tell by reading my manuals and browsing on-line the power factor seems to be similar with a slight edge perhaps to the 444, and the 444 has a bit of a nostalgia appeal to it, but then again the 460 is the 460 so.......

Any reason to go with one over the other in this scenario?

Just trying to see if I am missing anything. I am normally not the "what do I do?" type of guy, but not having shot either extensively I figure I'll just double check and see if I am missing anything.
