Does anyone have the Beeman dual caliber model ?
I have one I bought from WM for about $120 or so. I have shot over 750 pellets through it and love it. With good Benjiman 177 pellets it will shoot through 7/16" wafer board siding at 22 yards. The 22s shoot even harder. I wouldn't look at a 177 cal until I shot this gun. Plus at 22 yards it will shoot half inch groups.
Mine came with a 4X scope but I bought a Tasco Golden Antler airgun scope with adjustable objective and its much better. I mainly just shoot open sights though. Its an excellent gun for the low price I paid for it.
