I recently installed a Elite 6500 4.5x30x50MM Mil dot scope on my 6x284. Shot rifle at 100 yards.Placed a tape measure on target to measure where the mil dots are on the target at various zoom settings.For example on 10x 1st mil dot is 4" below POA.2nd 91/2" 3rd 15" 4th is 20". So I brought rifle into NV desert and shot at a rock that laser ed 295 yds. Book says my bullet drops 4.3" at 300 yds when sighted in for 200yds. (70gr Nosler BT 3,850 FPS). So I aimed setting the 1st Mil Dot on the rock. The bullet went over the top of the rock? So I aimed at the tip of the rock and hit it. I fired three rnds and hit it all 3 shots,severely wounding the rock.So Walking up to rock and all the shots were at the top of rock where I aimed. I thought they'd be lower ? Ok next set up a steel plate at about 550 yds. Book say bullet drops 27" with 200 yds zero. So I aimed using last Mildot (5th one). Again shots went over the target ? So I aimed with 4th same thing over the target ! Out of frustration I used 1st mil dot at the plate and I hit it! This is at 550 yds ???? ..............What am I missing here? Also targets were about 5 degrees up hill,elevation 4,000 FT develop load at sea level.............. Shot plate( 3/8ths plate) at 210 yds and that 70 gr Nosler completely pierced it.At 500 it look like it "Cut a dent" in the plate,amazing how powerful that cartridge is!
