Go big, or go home-
I got a Daisy single pump BB gun for Christmas along with the stamped metal target which had a hole in the center, shaped like a U and the tab bent back so the BB could hit the bell on the backside. NEVER USE ONE OF THESE UNLESS THERE'S PLENTY OF FRESH CORRUGATED CARDBOARD IN FRONT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You know the scene in Christmas Story where Ralphie almost shoots his eye out? A BB bounced straight back and hit me on the edge of my right eye socket. Scared the fertilizer out of me and I never used it again- I think I quietly threw it in the garbage.
That gun was great, until it wasn't. When I was cleaning out my parents house after Dad passed, I found it in the closet near the back door and thought I would try it. If you have ever seen cartoons of someone firing a gun and the slug falls to the ground, in a short arc, about 4' from the end of the barrel, that's about what it would have looked like. My Crossman pistol OTOH, uses CO2 cartridges and has three positions for the plunger- at the highest setting, it's pretty powerful and fairly accurate.
