A big selling point to me on the idea of 45-70 is widely available factory ammo, cases and bullets, I know there are any more wildcat handloading options, but my experience is limited and I do not have a good set up, also I am in college and my small apartment is not an easy place to handload along with my spare time being limited. 35 wheelen was also a thought but the pressure is much too high for the US krag action. But any research is much appreciated.
