I've been surprised by the "out of the box" accuracy differences between my 3 rifles. My Wildcat .22 mk2 and Air Arms .177 S510 sl carbine both beautifully accurate out of the box with marginal improvement over a couple of hundered pellets. My EDgun Lelya .177 on the other hand was almost on its way back up to about pellet 150! Over the next 50 or so it showed quite sudden improvment out to 30m. Still not doing the business at 40m but I now hold out more hope. Anyone else had similar experience?
