Though I regularly worship at the altar of John Moses Browning, the greater ease of disassembly and attaching optics to the Marlin 1895/336 puts me firmly in that camp for lever guns. I'm in favor of the Bear Tooth Mercantile options that allow you to delete the idiot cross bolt safety, go back to the old style solid firing pin, and beefy one-piece ejector, but the basic chassis is quite sound.
For a cast bullet gun for deer and pig, you are going to be hard pressed to beat the .35 Remington and .38-55. The .30-30 was conceived of as a jacketed round that does its magic with velocity that's on the upper end of what can easily be done with cast. While people can and do have great success with it using cast, I'm not sure that's really the round's highest calling. Though I love the .45-70, when you load it to get the flattest possible trajectory, the large bullet mass will start to pound you black and blue. In the sturdier actions, the .35 to .38 caliber guns will boot out 200-300 grains at speeds that should get you point-blank arcs on deer and pig sized critters to 200 yards or so. Probably nothing wrong with the .32 Special either, but zero experience there - just with .32-40 in single shots.
