Just been plinking with the Gamo air rifle in the garden. 6" circle target on white A4 clipped to a galvanised incinerator and +/- 18 yards away. Five shots later the group is reasonable (for iron sights..) but there are HOLES in the incinerator made by the .22 Accupells. Not having access to a chrono is it likely that, at that range and with those pellets, the Gamo is over the 12ftlbs..??? It's been a long time since I seriously shot air guns - I got the Gamo of Robbie to whack pigeons in the church tower so it's not used on a regular basis, only as and when.
I'll see if I can get some pics sorted
