You'll love it. 10/22's rock.
The 10/22 is a fantastic gun right up until you find out how many aftermarket parts are available for it, and then your wife starts yelling at you for spending $1000 upgrading a $200 rifle.
Enjoy it, the 10/22 is a great rifle and the price of 22 means you can get in a lot of practice. I would suggest going to an Appleseed with it and learning the basics of marksmenship before you build up bad shooting habits. Learning to shoot well is an American tradition that is slowly dying out...help keep it alive. As Col. Cooper said there are three thing a man should do well...Ride, Shoot Straight, and Tell the Truth.
Congrats, deter!
Where'd you get that case? I realize it's probably pretty basic, but right now I don't have a case for my 10/22 and something cheap and basic would work just fine for me.
