Question: what is the difference between 150 and 180 grain bullets?
Answer: At those speeds, and with both bullets sighted in 2-inches high at 100 yards, the difference in drop between 150- and 180-grain bullets is 2.82 inches at 300 yards, 5.73 inches at 400 yards and 9.69 inches way out at 500 yards. ... The 150-grain bullets also pretty well carry the same energy as 180-grain bullets.
