How heavy is the recoil of a rifle chambered for 300 Winchester magnum? A friend is picking his new rifle up next week and I am anxious to know how bad it will hurt him. He has a bad back and I am afraid the recoil will be a bit too much for him. I have seen several recoil reducers advertised. Do any forum members have experience with any of them? (NOT recoil pads) Please let me know. I appreciate all your help.
