A couple of other options include:

Ask your gunsmith about mercury recoil dampers. The one I have in my BPS shotgun weighs 5oz and fits into the buttstock. It doesn' t add too much weight (and because it' s so far back it doesn' t really change the way the gun swings, but that' s not so improtant with a rifle), but it is filled with mercury which hydraulically dampens the recoil. I installed mine for the times I' ll go to the trap club and shoot 8 rounds (200 shells of 1-1/8oz. 12ga. #8' ). It doesn' t really reduce the total recoil, but it helps a lot to smooth it out over a longer time, for it' s more of a shove than a kick. I' d bet it' d have a similar effect on rifle recoil, too. I do know that they are very popular on the trap and skeet range.

The other option not yet mentioned if having a muzzlebrake installed, if you don' t mind the extra noise. A good efficient muzzlebrake can reduce recoil by as much as 70%, which would make that 7mmMag a *****cat. The caveat is that a muzzlebrake will greatly increase the intensity of the report, which makes hearing protection mandatory at all times if you value your hearing, even in the field. A muzzlebrake is one of those deals where you don' t get something for nothing. But adding weight is the same way. The extra pound you add to a gun you plan to carry around all day will feel like 10 extra pounds at the end of the day. If you hunt from a stand, or stationary on the ground, then the extra weight might not be so bad.
