I can't comment on the 30 carbine, but I've enjoyed my Marlin 1894c in .357.
I bought the basic Lee Hand Press kit and .38 Special/.357 dies and now load my own plinking cartridges for 13 cents a piece (which is about the same as the higher end .22 ammo: Stingers, Velocitors, etc.). I haven't tried hunting deer with the gun, but if I did, I'd probably consider Buffalo Bore ammo for that purpose.
The only problem with buying the Marlin 1894c and the reloading equipment and components is that I then HAD to buy .357 revolver too.
