personally if i was hunting primarily woods I would go with the .270 win. For starters you probably aren't gonna find a shot much further than 200 yards and even that is pushing it so the flatter trajectory isn't gonna play much of a factor. Now, if I was hunting the plains or open grasslands and was gonna be shooting over that distance then I would like a flatter shooting caliber. Also, it's easier to find ammo for the .270 win and you'll have a wider selection so why sell yourself short on the ammo for no real added bonus based on your situation. On that note I hunt with the .270 win and I bought my father a .270 wsm so I like both guns but for different reasons.
