Here is my RWS/Diana side cocker, a modern Model 48 in .22 caliber. I have since removed the Leapers scope and RWS "droop compensating" mount (meant to compensate for barrel droop on barrel cocking springers, it's angled at 2 degrees down in the front) and have mounted an otherwise unused Leupold VX-2 3-9x in Weaver mounts.
This thing is amazingly powerful, approaching 25 ft lbs with the right pellet, going into the mid 800 fps range with the H&N 14.66 grain. Exceedingly accurate as well. Very much on the heavy side (way over ten pounds with scope), though, it's more of a fixed stand shooting than a carry around and hunt rifle. Perfect for baited backyard rats, it's taken its fair share.
