Hey guys, new guy here. I am only 20 and don't know squat about guns really. I only have a rem 243 bolt action. The marlin 45/70 guide gun in stainless really has me hooked on it. I really would like one! I know to look for the JM stamped on the barrel, but also I don't know much else to look for other then normal gashes or dings or scratches. I want to use this gun as a fun gun that people ask about but also to hunt hogs down here in FL. Any help would be great!! Oh and also what is a good load to start off with? I was leaning towards Rem 405 grain..
