I was shooting a mk 85 50 cal. loaded with 120gr of loose 777 my bullet was a .451 300gr xtp. with the mmp black sabot and a cci 209. If am am putting the bullet in the 1 1/2 inch bullseye ever shot at 70 yards how much it will drop at a 100 yards and at 150 and 200 yards. The 70 yards is the longest shot i can make from this shooting range.
