Buffalo Bore has some excellent .357 ammo if you are going to hunt with it.

5. 18.5 inch Marlin 1894

a. Item 19A/20-180gr. Hard Cast = 1851 fps
b. Item 19B/20-170gr. JHC = 1860 fps
c. Item 19C/20-158gr. Jacketed Hollow Point = 2153 fps
d. Item 19D/20-125gr. Jacketed Hollow Point = 2298 fps

That's getting close to 30-30 energy. While the ballistics would probably start to suffer past 100 yds. or so, This would make an excellent short range deer rifle.
