Robbo,
Thanks.
A gun like this was a favourite, deep into the era of percussion in Africa, as flint was easier to obtain than percussion caps.
They would have been used for anything up to the size of Elephant. Although, you do not kill an elephant with one shot out this old timer. A certain Capt Smyth, was written to have shot in excess of 110 elephant with a standard Long Land Pattern Brown Bess... :youcrazy: It has to be noted that he found his end under the feet of such a wounded elephant.
You found that plenty hunters and pioneers only owned 2, maybe 3 rifles, and tended to go for 10bore or 8bore's as they were very good allrounders for the heavy dangerous animals, and loaded with a handfull of .32's they are killer on smaller game at shorter ranges as well.
