Again, two bore rifles I had were, 1, a 12 bore H&H, 6-7 dram gun, weight 12.8 lbs and a 6 dram Manton 12, 12.6 lbs, both capable of shooting elephants. Very powerful, only to be displaced by the nitro guns starting in the 1900's. I once shot a deer with the 12 Holland through the chest out through the rear hip, shattered the bones and inbedded itself 3" into a hickory tree. Pretty powerful stuff.
