I think it comes down to what model of gun and which manufacture it comes from. I can shoot my Ruger No 1 375 H&H off a bench 20-30 times before I start to feel like it's having an effect on my shoulder. I had a Remington 700 custom 375 H&H and it took a few shots before I didn't want nothing to do with it no more. So I think it's in the gun and how it fits you.
