I replied to an old thread about this topic in another part of the forum, but got little response, so I thought I'd start a new thread here.
I have never loaded 44-40.
I think I have everything to do so...but I don't have possession of the Rifle, a Marlin 1894s bought new in the early 1990s, rarely used, I assume it's in like new condition inside and out.

snip...
In a min. .44-40 SAAMI chamber the neck diameter is 0.445" where it joins the shoulder and 0.4435" at the mouth. Typical case mouth wall thickness of Starline brass is 0.007," so .445" minus twice neck thickness (0.014") = .431", minus another 0.0015 to allow for safe neck expansion and fouling = .4295" max. bullet IF you have a minimum chamber. The normal allowed tolerance for a sporting chamber is +0.002" on diameters, so IF your chamber neck casts as large as .447", which My Marlin 1894S does, you can load a .431" bullet in that Starline brass! Try a dummy round for fit first!!!!

Can I assume the chamber of the gun I will be using is similar to Outpost75's gun ?
It seems I've read Marlin 1894s chambers/bores in 44mag are oversized, but they are a consistent oversize. So can I assume the Marlin 44-40 are consistant?
I have cast some of the Lee 200gr RF and sized/lubed them .430
and plan to crimp them into the crimp groove.

I need to load these for a trip, for use in the gun, at the destination. I'd like them to chamber and not create lead fouling. I have NEW vintage 'winchester' brass, never used/never sized. I also have some mix HS used brass of unknown history.
Any thoughts?
