I just purchased a new Pro Hunter. Mounted the Omega scope on it which calls for 150 grains of powder and 250 grain bullet. I loaded it up with 150 grains of pyrodex pellets and 250 grain barnes expander (Knight EZ load). Shot it three times. Third shot looked to be tubbling at 40 yards when it hit the paper. Bullet hit the paper sideways. I'm thinking too much powder for those sabots, but others use that powder load and bullet weight. Any ideas or experience with this gun and load? Should I be using a different powder? Really love the barnes expanders. I don't think you can get a better bullet for expansion and knockdown. Any info would be much appreciated.
