Took a couple rifles to the range today and something happened that I can't explain. The first is a custom 7 WSM with a Badger 20 MOA base and rings holding a 8-32X56 NXS pushing a 162gr AMAX @ 3034 fps. The range is flat out to 400 yards. The shooting bench is 7 feet off the ground making the barrel right at 8 feet off the ground when on the rest. The targets are about the same height, 8' 6", and are set up at 100, 200, 300 and 400 yds. The rifle is zeroed @ 400 yards. First shot @ 400, dead on. Then I move to 100, shoots 7" high. Move to 200, 11" high. 300 comes in at 11 3/8" high. How can this be? Does not follow the Hornady Ballistic program. The second rifle is a custom 300 RUM launching a 210gr JLK @ 3100 fps. Same base and rings, zeroed at 400. 5" high at 100, 9 1/4" high at 200 and 9 1/2" high at 300. My problem is I just can't understand how increasing the distance from the rifles raises POI and then the last 100 yards, both bullets drop so dramatically. What am I missing here?
