Several months ago I bought this ruger alaskan in 454 casull. Yesterday my nephew came for a visit and brought his smith 500 magnum. I was hesitant to shoot it knowing how painful my 454 was on my hand. But much to my surprise it didn't hurt my hand at all. I could tell it was very powerful but was amazed it didn't hurt. I can't explain why but maybe the weight of the gun, didn't seem as snappy as the 454. The bottom picture is the hornady ammo used, both bullets are 300 grains.
