I have a Merkel 140AE double rifle in .450-400 3" Nitro Express. Just the name seems like it should hit hard on both ends. But it is well balanced, heavy enough, fits me like a good shotgun, and I don't have to think when I shoot it. I just shoot. It certainly moves me around, but it doesn't hurt. I've used it while shooting elk, cape buffalo, and moose. No pain, and very effective.
