He really knew how to get the best out of an air rifle.
With regard to the leaking taps, my early (Airsporter Mk1's and 2's) with tapered taps seem pretty air tight, but later Airsporters certainly lose power due to air leaks at the parallel tap
I do have a .177 Airsporter S that is the exception and the tap on that gun holds presure very well. It is also nearly 1 ft lb more powerful than my .22 S, that does leak at the tap, so although everything happens very quickly during the firing cycle, leaky taps do mean less power
If you find a solution please let me know
