I tried some in my Interarms Mauser action 24" bbl. rifle. Groups were very good, about 3/4", with load data muzzle velocity close to 4K fps. First crow I shot with them looked like a black pillow exploding and I got really tickled. The crows feet were still clutching the powerline! Thats all, just the feet. Feral dogs? None left in my neighborhood. Feral cats ( trashbag neighbor USED to have about 50)? Not!
