When the bullet leaves the barrel it starts to fall. It falls at the rate of 32 feet per second per second, so if a bullet is in flight for 1 sec. it will be falling at the rate of 32 ft. per. sec. and will have already fallen 16 ft. At the end of 2 sec. it will be falling at the rate of 64 ft. per sec. and have fallen 32 ft. Besides falling at twice the rate the bullet is loseing velosity which makes drop more in a shorter distance.
For anyone wanting to play behond 500 yrds. for coyote or varmints there are several Wildcat rounds. For varmints I like to stay with .22 cal. so I like something from the .22-243 Middlestead up to something like a .22-284. I chose a .22-6mm, alittle more case capiaity than the Middlestead, and I don`t need so many steps to form brass as you do with the .284. I still have not desided on my final load yet, but it will be for now an 80 gn. Berger bullet at some where between 3,450 and 3,500 fps. it looks like. With a 100 yrd. zero it would impact abt 205 in. low at 1,000 yrds. That is 20 1/2 MOA if you click it in, but I doubt that I will do much shooting at that range as this is a coyote rifle, and a barrel burner, so I don`t want to over heat it to much.
