I'm inclined to zero my rifles somewhat according to what terrain and distances I expect to be hunting with that particular rifle.
Like Steelhead suggests, turrets are great for helping to resolve the holdover/drop issues, so his zeroing at 100 yards makes sense. He also hunts alot of the darker timbered, thicker stuff where 100 yards can be a looooong shot at times, as do I. Heck, iron sights would suffice in most instances.
So, for me anyway, zero's depend alot on the distances I expect to be shooting. Doesn't always work out exactly as one would want, so we all mostly choose the 200 yd. zero as it fits most all situations. I happen to zero most all of my rifles dependent upon where my highest trajectory with that specific bullet and rifle doesn't exceed more than +3.5 inches high from the bench. Most often, that gets me a 250-280 yard zero, such as with my 270WSM and 130gr. TTSX's.
Within the above ranges, there isn't any real difference between the standard .270 and the 270WSM. At longer ranges however, the 270 WSM's 250 fps greater velocity (which is somewhat past what I'd consider to be of little or no consequence/difference), exhibits certain benefits to those who intentionally seek out longer range opportunties, be it on paper or game.
Is 250 fps worth a slight bit more recoil and powder, given it's longer range attributes.....?
That's for each one of us to decide...........
