RE: .300 win mag recoil
Shoot more then 10 rounds, from the bench, in the summer, with just a t-shirt on, and the recoil will be evident. They are manageable, but they do kick. About 25 ft/lbs worth w/ 150 grain factory bullets. Double that of the .270 which has 12-14 ft/lbs w/ 130 grain factory bullets.
Shooting one just to shoot it, or while hunting, is a whole lot different than trying to shoot the best groups you can with it. It all depends on a number of factors, such as your physical make-up, and shooting position.
