Can understand what your saying about the power issue , and your completely right ... my weihrauch was putting out 10.5 when I had it .. a tinsy winsy more with a slightly heavier pellet .. but it was ( and still is ) accurate as you'd like ... it did however develop a fault after about 5 yrs and I returned it to a gunsmith for repair .. it came back 11.50fpe but no difference in accuracy .. still take a rat @ 40mtrs easily ( rested & in the right conditions )
