model 70, The terrain would matter depending on what type of rifle you might want to carry, whether it be a short action or standard action. A buddy of mine shot a 250lb buck in New Brunswick a few weeks ago. 2 shots with a 150gr '06. Neither bullet passed through. If I know I am going after 250lb+ deer and I have two rifles on the rack, a .270 and an '06, I'm taking the '06. And as far as brush or open ranges, the .270 has it on the open range. "Brush guns" such as a .35 Remington are usually faster handling, more compact guns. From 150 yds in, it's hard to argue with 200gr of .35 diameter Core-Lokt. Not saying the .270 is "bad", 'cause it's not. No one round or gun can be perfect for all situations. Although the Remmy pump comes close to the perfect gun.
