Given that the 48/52 comfortably hits or exceeds twenty in “export” form, it makes me wonder whether Diana with the 54 are the first maker ever known to understate an airgun’s power, or whether they’ve done something to the 54s to make them a bit less powerful because that works best with the sledge?
Similarly, I wonder about how well the sledge would work if you properly de-tuned the action to make 11.a bit. I assume that U.K. spec factory models just rely on a TP restrictor, giving an inefficient action with plenty of surplus energy to work the slidey thing. What would happen if you increased the efficiency of the action to generate sub-12 m/e (short-stroke, sleeving, etc), while decreasing its total energy? Would the slidey thing still work properly?
