That's a provocative question that sent me comparing ballistics. Physics teaches us that for every action there's an equal and opposite reaction, hence recoil in a rifle. Looking at the managed reocil ammo from Remington, they've downsized the bullet from 130 gr to 115 gr. and reduced the velocity (voila', less recoil). Comparing the managed recoil 270 to their standard 243 load with 100 gr. bullet, my choice would be the 243 as it has greater velocity and downrange characteristics. All that being said, Montana is a very different place to hunt than Michigan and if your shots are bound to be less than 100 yards then I doubt the deer or the shooter will notice the difference.
