Also you won't have any troubles with deer out to 400 yards with cartridges like the 270, 280, and 30-06.
Recoil is different for different people. I have a very bad shoulder, that is, the matter that is supposed to be between the two parts of the shoulder joint is completely gone. All movement is now bone against bone. Try telling that shoulder that the recoil from the 300 Mag is not bad.
If you look at the picture of the Shooters Friend Recoild pad on the Cabelas site, you can see where this pad makes shooting higher recoil rifles much easier. Its soft and nearly 3 inches wide at the shoulder end. This spreads the recoil are out over more distance. Whatever its made from absorbs recoil like a sponge. They claim it reduces felt recoil by 70 percent. They are right.
