Most of us shoot .22 long rifles in our 22's. I had several occasions where a .22 shot was useful. I once had my airplane in a large wooded hanger that was infested with pigeons. Not wanting to put holes in the roof I found the .22 shot quite effective in pigeon control. So my question is this. Why the heck did they make a .22 long & has anyone ever shot one & is it still manufactured?
