RE: .45 vs .50 on elk @ 200 yards
You might consider the tougher 300gr saboted bullets with 3 pyrodex pellets. I've had good success with this and if you miss the shoulder, you will likely have an exit wound. Knight markets a tough 300g jacketed bullet. Similarly, the barnes 300g expander likewise holds together although my sense is it does not penetrate as well because of its expansion. Both of these bullets shoot plenty flat for a 200 yard shot. They do kick however. Not all of my guns will shoot them as accurately as lighter bullets or with a lesser charge--still they shoot good enough-ie 21/2" groups. Give them a try--they will work!
