My Crossman air rifle will fire both pellets and BB’s.
As a practical matter, I shoot only stray cats that hunt birds at my feeders and squirrels that get out of hand. I shoot BB’s at what I think of as half power. The intent is to discourage rather than harm or kill.
However, the info you provided will be useful should the need arise. When pumped ten times the range and accuracy are quite effective.
I had a .22 caliber Crosman air rifle when I was in high school. At 10 or 12 pumps it was a surprisingly powerful weapon. We could shoot the metal tags off of telephone poles at fifty feet or more.
