My .50 Hawken and Renegade both love 90-95 gr 2FFg, and the Hornady Great Plains, 385 HP and the T/C 350gr. HP, both are deadly, have taken deer out to 165 yards. Have taken 42 deer with these b ullets in .50 adn .54, never lost one. Round ball is great out to 100 yds, but energy levels drop quick after that.
