If you run the Nosler B-Tip 250gr .366 out at 2550fps will give you 2039fps at 300 yards and 2309ft/lbs energy. That is shooting far enough and still hitting hard! It'll mushroom enough! If you sight it in at 250yds it will be -4.77" at 300 and +4.20" at 150. It sure makes for a good all around PG killer.
