First of all I do not think 29K for a 600 German Nitro Express is giving it away, in fact this price is quite high.
Now about the 600 Nitro. I have a Thys 600 sidelock ejector that weights 12 lbs 6 oz. I load a Woodleigh 900 grain solid with 160gr of IMR4831 and velocity of 1970 ft per second. I shot a Bull Elephant in Zimbabwe with a frontal head shot and the bullet penetrated 37". How much more penetration does one need. It killed the elephant. That penetrated a .623 hole more than one yard of bone and flesh. Yes this rifle has recoil.........
