I’m not sure what the purpose of it is, since it’s not a toy and isn’t good for target practice, hunting, or home defense.
Your right it is not a TOY
It very good for target shooting and practicing your shooting skills and well take small game out to 25 30 yards without trouble.
They are a very useful tool.
And your right about about not being very good for self defense but I don’t just think many crooks would just stand around to be shot with one.
I second everything you say. I had a 17 caliber Crossman rifle (I forget the model) with pump and CO2 capability, firing BBs or lead pellets and it was great for target practice. It would punch a hole through 18 gauge sheet steel though I never tried it on a varmint. My sons and daughter would use it under supervision - most of the time and were taught to give it all the respect they should show for any firearm.
