If you are stuck with factory ammo I would say Car-Bon 305 penetrater load,Fed. 300gr. Cast-Core hunting ammo and Garret Cartridges. I load a 320gr.WFNGC LBT from Cast Performance traveling 1300fps. in my 7-1/2" Ruger Super Redhawk 44mag. I would use a good hard cast gas check bullet for penetration to go through heavy bone and mass. Mark
