RE: 30-06 or 7mm rem mag for deer?
 

with what you have now, I'd take it to the shop and have it punched out to a 280AI and save the money from a new rifle to invest in ammo or a trip or something... the AI will get you so close to a 7mag it'll be hard for the animals to know what has smote them... and you'll have a lot less recoil from the AI... better case capacity to bore ratio, more thump for your money... just my humble opinion, but then what do I know... :D
