The bellowing .300 Winchester magnum may turn the grass brown and rattle rocks loose from the mountain, but with factory ammunition it is only about an inch flatter at 200 yards (with the same 150-grain bullet) as the much less punishing .30/06. As this is being written I'm glancing over a ballistics table from Federal Arms Co. (the figures are similar to those from Winchester, Remington, et al) and the mid-range trajectory of mild-recoiling .270 Winchester with 150-grain bullet is 2.9 inches. The 7 mm Remington magnum shows 2.0 inches at that distance with the same weight of bullet, and the .300 Winchester magnum shows 1.9 inches with that same weight bullet. The old .30/06 shows 2.6 inches, and the .308 2.6 inches. Now then, the man under hunting conditions, who can hold closely enough to make use of 1 inch at 200 yards doesn't need to be reading this. He already has a rifle, presumably one that never misses.
