Well, if you are constantly shooting it, its a waste. Otherwise, what are you using it for? Either way. Whether you are shooting it, or storing it, its a waste of money.
Like I said, its not my hobby so I dont get it. Im just not a money spender, myself.
You got a $20 bill burning a hole in your pocket and you can pick up 2000 rds of 22 LR or go buy a burger.
What to do?
If you're constantly shooting it, and don't enjoy shooting ... maybe it's a waste.
Otherwise, it can be pretty cheap entertainment.
I don't know anybody who shoots a lot, who considers either his time or his money to be wasted.
