I don't see any discussion that points out the limit, pressure, etc differences between the old 130+ year old trapdoors and the new, presumably stronger new and safer replicas. Also, I'm reading on this board that old Trapdoor barrels have relatively soft steel barrels and therefore like lead vs JHPs. If that's true, then JHPs should be OK in new replicas. Please confirm or refute what I'm assuming. thank you.
