I was at a local custom shop and they have started building double rifles. I asked some questions and they are taking well built SxS shotguns and re barreling them for rimed cartridges. varying from 30-40 krag, to the 500 nitro express. These are being built for people who want to venture to Africa ( for the big caliber cartridges). While I am not going to get to venture to Africa for a while. I was thinking about one in a smaller caliber for American hunting. Deer, pigs even for elk and moose in thick cover. The question. What rimmed cartridge would you chose? I was thinking if I ever went to Africa having a double would be nice. So do you go ahead and get a .40 + caliber rifle like the 450-400, 450, or 500. or do something like a 45-70, 45-90, or even smaller 30-40 krag. maybe a middle weight like the 9.3 x 74r. or the 375 fm? What would u want?
