Why should I buy a .22 Magnum rifle? Was at Cabela's today...found a used Marlin .22 Mag tube fed, bolt action rifle (don't remember model number) ex.cond $230. I got a .22lr rifle...why .22 Mag...why not jump up to .22-250 or jump down to .17 cal? I went and checked the ammo...not badly priced (though not as cheap as .22lr) Ammo looked like stretched out .22lr rounds but they also had little rounds that looked like little .223's! Never had or have shot a .22 mag. So why should I get it .22 Mag fans?
