12 bucks for a box of 550 rounds at wal-mart. 10/22 is simply a model that ruger makes, it is chambered in .22lr.

Probably the too most popular rifles would be the Marlin model 60 and Ruger 10/22. The ruger is magazine fed and has tons of aftermarket accessories. The Marlin 60 doesn't really have that many aftermarket stuff but is very reliable and less expensive. Both are semi-auto.
