I got on the hard cast bandwagon many years ago with my .41 Mag Ruger Bisley. The Beartooth 250 grain Long Flat Nose (LFN) bullets were incredibly accurate giving me four-inch 100 yard groups from that scoped handgun. But I was totally dissatisfied with their performance on deer. I'm a heart/lung shooter and every deer shot in the boiler room with that hard cast flat nose bullet ran and ran. Long tracking jobs. They are very effective with bone breaking shoulder joint shots, which put them on the ground, but often needed a second mercy shot. For my kind of hunting a soft lead .50 caliber round ball in the lungs was way more effective than a hard cast conical.
