So my Diana 56TH arrived today (thanks @Lewis !) and I am having a good ol time with this thing. I wouldn't quite call it "recoiless" but its definitely easy and fun to shoot to say the least. 19fpe with JSB 15.89gr and its just pellet on pellet on pellet at 30 meters. This is my best group so far with it. 20x shots into about a 1/2" string. I was going to tune this thing for a bit more power but at 19fpe I dont really think I should.... anyone have any strong opinions on that?
