Keep it and shorten it. Swapping wont gain much and you wont have enough change to justify changing to another rifle. Take into account the costs of swapping ammo etc and just like that you spent money you were trying to save. Some of the guys here may not like to hear it, but swapping a 270 for a 7mm08 is even more pointless as both are close enough to the other in performance that I would not bother. And while the 308 might be cheaper to feed, depending on its ammo preference, it may not be cheaper either....Certainly the animals cannot tell the difference...
Shorten it a bit and suppress it if you want, but personally the only wise words I can give you is "better the devil you know than one you dont...."
