I have an encore pistol chambered in 7mm BR. It shoots 120-140 grain bullets extremely well, but I have yet to take a deer with it, as I am just getting into handgun hunting myself. I can tell you that recoil is not an issue with it, as it is a very "sweet" shooter. It's limiting factor is that it will have a shorter range than the 308 and you will most probably have to reload. I would say 150 yards or less. That is not a problem for me as I did not build it to be a +100 yard hunting gun. The more experienced guys on this site indicated to me that this was plenty enough gun for short range whitetail hunting. Another alternative might be the 7x30 waters, which is available in factory ammo.
