Dale, is there any reason you are specifically tied to the 30-06 for this venture? If you are looking at recoil reduction alone, there are a lot of 6mm's out there that would be a great choice. Any 6mm using the 85 gr Sierra HPBT Gameking, is an absolute killer on deer inside 100 yards. Any cartridge between a 243 Win and 6BR would get you there, and recoil would not be an issue. If the 03 has been sporterized,even a clamp on muzzle brake can get you some needed recoil reduction.
