I would surmise that they used a .303 FMJ load per military doctrine at the time.
What load did you fire out of it? For the purposes of paper punching I bet a low velocity plinker load would drop the point of impact a lot closer to POA. Maybe a 150 grain bullet at 1100fps or so. If I were hell bent on deer hunting with it I would load a 190-200 grain cast bullet at 1600-1700 fps MV and see where it hits- probably a whole lot closer to the bullseye than what you got, and with plenty of oomph to kill a deer. Let me know and I'll bring you a fistful of them to try.
