No one has mentioned the .340 Weatherby, so I will. I had one in the stainless sythetic Mark V action with no brake - one range session was enough and someone else now owns it. Interestingly enough, I don't have any trouble with any of my three .375 H&H's or either of my .458 win mag. Perhaps it was gun fit, but I hated that .340 Weatherby rifle.
