A Rossi single shot .22/.410 when I was 12. Bought it with yard working money. Next was Savage .22lr bolt action and then Ruger 10/22 at age 13. At age 14 was the Walther g22, Baby Ealge 9mm, Marlin 30/30. At fifteen was the ruger M77 Mkii Compact in 7mm-08, Mosin Nagant, and Remington XR-100 22-250.
Mind you I bought all of these with my own money.
