RE: 270 wsm is it flatter than a 7mm rem mag
They are to close to call. According to Hornady, If the both shoot a 150 grain bullet and both are zeroed at 300 yards, the 270 WSM will drop 9.7 inches at 400 yards while the 7 Mag will drop 9.9 inches.
Its so close that it only depends on whos ballistics you use. For sure, no critter would ever know the difference.
