I love my 22's. Marshal used to give me a raft of sh** about the fact that they are actually my favorite to just take out and fire away.
But that is because I had 22's all my life and that was before I ever had anything else..( other than a shotgun of course) so my 22's are what I cut my teeth on.
Then............ then a few years ago, I surprised him and bought him a little 22 Browning.. Guess who shot their first squirrel and acted like a 10 yr old kid? Yep... you guessed it.
And now when we go out to just river shoot ( you know.. turtles, sticks floating, snakes) guess again who grabs the 22 and heads to the truck?
Yep.. Right again..

So no matter what caliber a gun is.. they are still fun to shoot.. But you're right.. you can buy lots of ammo and do lots of shootin' for very little $$.
I have Rugers too, but now I think I need a few more.. LOL
