Looking at the Pedersoli linup and my options are either the Sharps, trapdoor or rolling block. Looking for something compact for range fun and deer hunting from a tree stand. I will be hand loading my own ammunition to old specs using cast bullets. Out of all three which would you all pick? I have researched the strengths of the three and already understasnd the trapdoor is the weakest design but I am most drawn to that one. I am also open to other suggestions to early single shot 45/70 carbines.
