My experience is limited to testing the 500 grain Hornady solids on a large hackberry tree back in the day. The rifle was a Browning safari which belonged to an older friend and we did our shooting by car light in the dead of night on another friend's farm. The 500 grain solids easily went through a tree about 2 feet in diameter. I don't think you need to worry about a lack of killing power (or recoil!) with this cartridge loaded with modern powders and bullets. Harry Selby seemed to like it just fine in a push feed post 64 Model 70. The size is a plus I think and the cartridge is attractive and feels good in the hand. I'd say it's worthy of being called a modern classic.
