If practicing is what you're after. You can reload your own ammo and reload it lighter (down to a 30-06 or 308 level). The recoil will be MUCH easier to deal with, you'll save money over factory ammo (probably pay for the reloading supplies after 100-200 rounds), the barrel will last longer and you won't have to mess with your rifle.
You read on the web all the time about sub-1/2MOA groups etc. The fact is for a light packing rifle, if you can shoot sub 1-MOA at distance from a hunting position, you're in pretty good shape from an accuracy perspective. If you put a brake on the rifle and then use it for a packing rifle, your ears will not like you! I personally will NEVER have a brake on a rifle I carry hunting (setting up for LR is a different story).
A good foam filled composite stock will probably lighten the recoil somewhat if you go that way. My personal packing rifle is a 7RM that weighs 7.9lbs ready for hunting, it has a Brown Precision foam filled stock. Its recoil is softer than heavier 7RM's that I shoot, I believe the foam filled stock has a lot to do with it. http://www.brownprecision.com
