I'm not sure what a "Rem-Marlin" is, but I have a Marlin 1894 20" 44 Magnum; and a Henry 357 Magnum. I have two 44 Magnum revolvers (5" & 8-3/8") and four 357 Magnum revolvers (3", 4", 6", & 8-3/8").
Unfortunately, my Marlin 44 won't shoot anything straight, except a .431 slug; and I'd probably shoot a .432 if such a jacketed animal existed. Heck, maybe even .433 - no telling how giant its bore is. It's a disgrace. So I only shoot one load for it, and it isn't suitable for my revolvers (I'm not comfortable blowing .431 bullets through guns that shoot .429's just fine).
But the .357 Henry is a different story. I also only load one loading for my Henry: a 158 grain JSP, using W296 with a charge weight a little over published max (not over max in older manuals). But I also shoot that loading in my revolvers. It's shoots really nice in the 6" and 8" bbls. But it's boomy and kinda silly through the 4" bbl; and just ludacris in the 3".
However, I also load a 158 JHP using 2400 and it's a great shooter in all the guns - maybe a bit boomy in the 3," but is just fine in the 4" (what I shoot the most). I would consider that loading to be a very good all-around compromise. It's shoots 100 f/s less in the Henry compared to the W296 loading; but hey, everything in life is a trade-off.
