The biggest problem I have heard about 338s is when people buy them in light custom/stock rifles under the premise they will be carried a lot & shot very little. The recoil in a light rifle is fierce and then people don't shoot as much as they would like to. All too often, just in the week prior to the hunt...
there is an article on AccurateShooters.com that goes into great detail about the 7mm caliber being more accurate at long ranges than other calibers, due to bullet weight vs. bullet length and BC. excellent information in the article and explains it much better than i can.
Gonzilla, you are right about the weight to caliber in regards to recoil from a 338. when that cartridge is in a sporter style hunting rifle, it is vicious. when mounted in a heavier, tactical rifle, it's much more manageable, especially when a muzzle brake is installed.
the difference i see between the 7mm caliber and the 338, is muzzle energy and the energy retained downrange at a long distance. if it is a target rifle, then the retained energy downrange is just needed to punch through paper. on a sniper rifle, they need the downrange energy to be able to eliminate the target, so there for the 338 is better suited for this job than the 7mm, plus being a larger and heavier bullet it will retain that energy better.
