Vapodog,

I say if they want to "play" with their 45-70's in Africa for DG --- let them. Either they won't ever go, or they'll take the cheapy Plains game trip and pop some antelope and now claim they've "done it", or they'll find the 45-70 is not a legal DG cartridge in most the countries (I wonder why?), or the PH's won't take them out for DG armed with a 45-70, or eventually the process of "natural selection" will eventually take care of matters.

Good Luck and Good Hunting,
EKM
