[QUOTE="entoptics, post: 1940159, member: 104268"] This. Don't forget that the bullet is falling like a stone at this distance. Ran the numbers in JBM, and the bullet is dropping at roughly a 5.5% grade. So from 1750 to 1770 yds (20 yds), the bullet drops about 40 inches (1.1 yds). Even if you have a good backstop to see splash, if it's not right behind the target, you can get a false sense of drop. For example, even if your berm is only 5 yds behind the target, and you get a berm splash that appears to be a dead on in elevation, that actually means you're about 10" high at the target. This can get even more confounding if the target is on a steep slope. If you have the option, I highly recommend finding a huge piece of cardboard (or tape a few together), and put that right behind the target. Having a 6'x6' target board, or bigger, will really help you learn where your bullets are actually going, and will give you a sense of the "group size" you can expect at extreme range. [/QUOTE]
