I say skip the .270 WIN and jump to a .30 cal bullet(.308 WIN). More punch and within 300 yards, really out to 500 killing deer sized game should be easy.
That's just me though. I had a .270 WIN and rid myself of it in favor of a .308. With roughly the same recoil( with the advantage of less recoil going to the .308) from similar weight rifles I thought why not use a bigger bullet? The .270 WIN trajectory is better but learning trajectory is something you will have to/should do with any caliber you use.
Anyway that's my input on why I changed the .270 WIN and upped it to the .308 WIN.
