Curious about .22 magazines for my Leshiy 2. Mine came with magazines marked s5.5. I take it this means slug magazine. I called EdgunWest and they said it shoots both slugs and pellets. Maybe even a little better for pellets than the non-slug marked magazine. My gun seems to shoot fine with pellets, I haven't tried slugs. JSB 18.1's are a press in fit. Not tight but not seated without it. Hades 15's are very easy to seat. I'm just wondering what is really optimum from those that have tried both over the long term.
