Come to think of it, I guess the sabots breaking away shouldn't have anything to do with it, considering that years ago TC had their break-away sabots which performed pretty darn good. I got the best grouping with 100gr. 777, less than that and the group would open up at 100 yds. Maybe next time I will try some xtp's with the knight sabots. I just hear about people shooting 2" groups at 200yds. Maybe there is a little luck involved in a group like that ?????? Just kinda fun playing around with different combinations. Thanx !!!!!
