Remington 700 tactical conversion
 

Hi all, last year I bought a Remington 700 chambered in 7mm Rem Mag with a Bushnell scope and 3 round removable box magazine. Nice hunting rifle, but I'd like to make it into more of a tactical rifle. I have a bi-pod on the way in the mail, but I'm having a hell of a time finding a higher capacity box mag and 3 rounds just won't cut it. Any suggestions?
Thanks!
