[QUOTE="Steve Douglass, post: 20124, member: 2879"] My first suggestion is to locate the thread in the optics section named "Is it a mistake". This is a good discussion on the Mil-Dot reticle by several members, each having different perspectives. The actual distance between the dots i.e. 1 Mil is 3.6 MOA or 3.6"@ 100yds, 7.2"@ 200yds ect... Now unless you have a ballistics program, the best way to work this out is at the range, but I ran it through a program based on the info you provided. Now,if you're zeroed at 300yds and you're hitting the target 2.5" high at 100yds then 2.5"@ 100yds is 2.5 MOA. So your come-down from your 300yd zero would be 2.5 MOA or 10 clicks on the elevation turret if it's a 1/4 increments. Now you could also use the mil-dot reticle and change your point of aim. To do this, you would divide your come-down, 2.5 MOA by 3.6 which equals .70 Mil. So your POA would be .70 MIls low of center target or .30 Mils from the first upper dot with ref. to the cross hairs. Make sense? Now, to determine other come-ups and downs you would actually have to go to a 200, 400, 500 yd target and record where the bullet hits the target in inches from center. Example, if you shooting at a 200yd target and you hit it approximayely 3" high, calculate your MOA, 3"/ 2= 1.5 MOA or 6 clks down or using the mil-dot reticle your POA would be 1.5/ 3.6= .4 Mils low of center. Give this some thought. Below are some come-down and ups based on your info. Try them using the elevation turret. Zero 300 yds. Set the turret to zero and lock down. 100 yd come-down= 2.5MOA or 10 clks down 200 yd come down= 1.5MOA or 6 clks down 400 yd come-up = 1.8MOA or 6 or 7 clks up 500 yd come-up = 3.8MOA or 15.2 clks up These are estimated based on the limited info I have from your message. All these C-ps and downs start at your zero. Good luck! -------------------------------------------- Expeience the best, Judge the rest!! [/QUOTE]
