Looking for a new .22 to shoot squirells and what not. Nothing fancy just something to take with me on the 4 wheeler. I am thinking of something made by Savage. So what are the advantages or disadvantages between a .22 LR or a .22 mag. I can't hardly find a .22 LR anyhwere, I guess because of christmas. But would I need a scope for a .22 mag or open sights. What would you guys recommend?

Thanks in advance, JB
