Hi I recently bought a Weihrauch 97k which had been tuned from a mate, it shoots very smoothly, you can keep a pellet on top of the scope while shooting, its a .22 and i was using RWS Superdome pellets14.5gr, after zeroing i tried shooting out to 55yds, it was not on the mildots at all, i then tried JSB Exacts jumbo diabolo 15.89gr, which gave me 3 mildots at 55 yds, i then managed to knock out the red dot on a shoot and see at 55 yds, needless to say it was not windy and it was on a bench rest, but just shows you what a change of pellet can do.
