Of course, I'm referring to the US standard, not the sub 12 fpe standard. I will have to say the RWS D54 and D56. I've shot magnum springers that is close to PCPs in power, but they are like riding a bull and I've shot springers that are as accurate at close range, but they are nowhere near the power of PCPs. I think the D54 and D56 balances power and accuracy the most.
