Look for an older (pre-2008) Marlin with the "JM" stamp on the right side of the barrel, those are the guns that Marlin made, not the sometimes-junky rifles coming out of Ilion NY these days. I'm currently holding at eight Marlins, including three 1894's, in 218 Bee, 357, and 44 Mag. Micro-groove barrels WILL shoot lead well, you just have to slug your barrel and match bullet diameter accordingly.
I've tried to love the Rossi guns but just can't......they're just not the same, though they do offer them in some calibers the Marlin won't safely handle. I've taken to thinning the forends on my 1894's to feel like the Winchesters, and it's the best of both worlds. In terms of takedown and maintenance the Marlin has it all over the other guns, field-stripping for cleaning involves one screw, and three other parts. And scope mounting, either atop the action or in front of it, is a snap.
Most 1894C's have an ammo preference.........some with happily feed 38's, some will not, but they ALL feed 357's just fine. They get slicker with use, the stainless guns even moreso, and if you get lucky you might even find one of the rare stainless 357's they made before Remington took over production. There are far more stainless 44's on the market.
At this point in time, older Marlins are one of the better investments you can make in Heavy Metals.
