I was going over my targets and load data and my best group is 3/4" center to center using barnes 290gr with 100gr of blackhorn 209 at 75 yds. I used a crushed rib sabot that slid into the barrel with little to no resistance. On a scale of 1 to 10 resistance was a 2. At the range it is not a problem but I am concerned that out hunting is it possible for the sabot to slide some and create a gap between breech plug and bullet. I measured my bore at .502 and and the black crushed sabot and bullet at .502 to .503. Any opinions on using the red crush sabots for a tighter fit.
