I'm thinking about purchasing a rifle for my girlfriend and wanted some recommendations. She is fairly small so nothing over powering. She has been able to shoot my .410 over/under with pretty good accuracy and control. However i'm looking for something with more practical uses. I understand .22LR are difficult to come by and wouldn't mind finding a caliber that is both inexpensive and widely available. What's a good alternative to .22? To reiterate, what do you guys suggest for a long gun that doesn't use .22 ammo and would be good for someone who is undersized. Basically I need a gun for a child. Thanks!
