Lack of powder had slowed my accuracy search with my S&W 686 with a Vortex Venom 3-mildot sight but I think I am finally getting somewhere. Hornady 158gr. XTP over 13.5gr. of 2400 powder is producing 3/4" groups at 50 yards. Sighted in about 1/2" high at 50 yards I am hitting about 2-1/2" low at 95 yards. I would really like to borrow a chrony but don't know anyone with one. I am considering increasing the charge but am also wondering why. My main targets will be coyotes and groundhogs but I would really like to try for a hog in the future.
