Well I found the bullet/sabot combo that shoots 3/4" groups finally. I just have to be the person shooting them now. My dad came out to the range today and really connected with my Knight Bighorn. Guess I still have a few things to learn even after 30. Anyways the Preciscion Rifle HP Elite 360 grain bullets paired with a Harverster crush rib sabot over 80 grains of 777 FFG make a fine pairing in the Knight Bighorn. It took some trials, but this is a good shooting load. My dad was laying them on top of each other at 100yds with my aperture sights and I was about 1.5" groups. Think this will be the elk load. Just need some practice now. Forgot how good of shot my dad is. Guess there is always time for a reminder.
