I picked up a Marlin 1894c when I went on leave a couple weeks ago(357 lever action), and have got to say that it is probably my favorite rifle now, in just the short time I have had it. Do a search on the web about a .357 in a long gun, and you will see that it is a total different animal than out of a handgun. If you want my vote, I say a .357 handi reamed out to max....you get the same versatility as mine, but you get the added ability to use the max shells that rival a 30-30. If you plan to cast, you can load up 100 shells for 4 bucks or less.....38spec/357mag/max. Lots of mold choices too, plain base, gas check, swc, rn, rnfp, wadcutter, plus any jacketed...pretty good deal if you ask me. You would be good for small game with the special shells, up to deer/bear with the right heavy loading....good luck choosing!
