Re: 30-06 vs. 7mm Rem Mag felt recoil
There are two ways to minimize the recoil of the 7mm Mag that come to mind.
The first is one of the recoil pads made from space age Sorbene rubber like Kickeze or Pachmayr Decelerator Recoil Pad. They only fit well when they are ground to fit the stock. It is a task better left to a gunsmith. There are slip on versions too as well as a strap on shoulder pad made of the the same rubber (by Past).
Second would be getting a semi-auto gun like the Browning BAR. Mine does not kick all that much more, if any more, than a 30-06 bolt gun.
Having said all that, I have a 7mm BAR and would not agin buy any high power belted case gun. If you are a reloader then 7mm Mag is tough on cases. If you reload in a regular manner you may only get a couple of reloads out of a case before you get a head separation right above the belt. Most 7mm chamber are cut with a generous amount of room for the shoulder of the case as the case head spaces on the belt not the shoulder as do all beltless rimless cases. When fired the shoulder moves forward stretching at the junction of the belt and the case body with the eventual head separation if you are not on top of case inspection after every firing. Belted cases for a reloader are a pain. The solution is to adjust the sizing die to not move the shoulder back during sizing or at least not more than a few thousandths. If you only shoot commercial ammo none of this is a problem as you'll throw the cases away (or recycle the brass).
