I've read many postings on reloading for the trapdoor and they all recommend loads on the weak side such as Cowboy action loads. Is the trapdoor action really that weak. I measured the metal around the chamber of the rifle and found it is about 5/16" thick. Then I measured the thin section of the Colt SAA and found less than 1/16". A weak trapdoor black powder load would be 55 grains and a normal Colt load is about 40 grains. Is the trapdoor made out of brittle cast iron. Is the Colt made out of tool steel. Looking at the dimension I'd think the 45-70 trapdoor was overbuilt for the loads it's made fire.
