I agree. I had a nice talk with John Nosler a few years ago. He told me a story of shooting an H&H magnum and the bullets blew up right underneath the hide on the elk he was banging away at. Took him 8 shots to bring the animal down.
Penetration, he explained to me, was the key and cast bullets penetrate! For decades surplus Krag rifles using Military ammo were considered perfect elk medicine. Why? Hard long slow moving bullets that shot straight thru the animal.
I am trying to wean myself off of jacketed bullets to shoot more cast. I shoot a lot of old guns. They take kindly to cast bullets. Most of my hunting is birds. So I shoot a Parker, Lefever and Fox gun. Old guns rule.
