Exactally what dave says +1 
I found the 250gr MZ with 110gr 777 and the Orange Sabots shot best out of my Knights !
Last year shot a Big doe @ 130yds and she only took about a 10yd nose Dive when I walked up on her she had a Baseball sized exit hole in her !
Killed a big 8 pt with same results !
I found that the Flat based Bullets shot better than the Boatail Bullets !
