I have to tell you that I haven't seen these two new calibers on the streets yet. I'm by no means into the magnum craze, feel the 06 will do anything I need it to do. Come the think of it I haven't even seen them on the auction sites yet. I usually checkout gunbroker, gunfinder and a few of the others on a regular basis. I guess I'm one of those guys that prefer tried and true over something new. Like you said it may be obsolete in a few years and even if it isn't ammo and components such as the brass are going to be real expensive for a while. The only real advantage is the short action, but the vendors don't take advantage of this by giving 2 more inche of barrel which would do more to help substantiate what they claim it will do. I have however had the opportunity to shoot the 7mm and the 270 wsm. Recoil I would say was about on par with their long action counterpart with a Pachmeyer Decelorator, so maybe a bit more kick. Otherwise I don't think it offers any thing to make me want to buy one.
