I'm looking to pick up a new scope and was wondering what everyone thought about whether I go with a 3-9x40 or a 2.5-8x36. I hunt whitetail only in thick areas where the average shot is about 50 yards but in some areas I can shoot up to 100 yards. Gun will be a 270 or a 7mm-08 and these are the only two scopes I'm considering.

Thanks.
