I've decided that I want to get a Uberti 1873 replica but I dont know what caliber I want to get it in. I first thought that 45 long Colt would be good but then I woundered if I should get a .357 would be the way to go. Which would be best for whitetail deer and which would have the best knock down power? Since I live in Pennsylvania most my shots will be within 100 yards. Any imput would be appreciated.
