Sighted in my new gun today. Its a 300 mag. Sighted in for about 2 1/4" high at 100yds. Almost 3/4 high at 200. We shot at three hundred as well and I was hitting only about 5 inches low. (grouped three shots about the size of the top of a beer can.) All this with regular 180 grain Rem. Core Lokts. Does that seem like hardly any drop? I thought it would be three or four inches more according to the ballistics on Remingtons web site.
