[QUOTE="daveosok, post: 14501"] This is why I hate millradians. I haven't used the mildot master so I will only tell you how you have to do it the old fasion way. You must first find the target size in yards which is a decimal equvilent, where yours is 12 inches compared to 36 inches. 12 / 36 = .33333333333 I rounded off to four decimal places an old machinist habit but I guess you could do three places and still be ok, however when you get out their to where these guys are shooting on this board the small stuff counts. .3333 X 1000/number of mils taken up .3333 X 1000 = 333.3 3.333 / .5 = 666.6 Its easy when you have a multiplier of one half. But say it was .7 mils that you had to devide by, you'd need a calculator or the mildot master. Since not everyone has a computer for a brain and field math with what equals what at certain distances can get you either right on target or your way off the bubble. This is why I like MOA reticles, whatever it is in inches is what you use, not a fractional decimal equivilent of 36 inches. MOA to me is much easier. Object in size of inches / number of moa X 100 Now your saying that you have a target that is 12 inches in height. In MOA it would have a height of 11.459 moa. Since everyone agrees that one moa is one inch @ 100 yards will will stick with the 12 inches. 1 Mil = 3.438 MOA You have half a mil registered as your range using a target size of 12 inches. 12 / 1.719 MOA X 100 = 698 yards compared to 666 with the mil dot. (for the rest of you reading this jump in if I'm wrong and correct me!!!!) You must be exactly correct reading the mildots or moa and since they have yet to put a mildot scope on the market that has it sectioned off from the center of the crosshairs to the first mildot where their should be 7 very small dots and the egde of the first dot indicating hundrenths of a mil or .1, between each dot their should be 6 dots. But their isn't, unless you have one custom made say at Premier Reticles. Since Leupold uses USMC mil dots, the dot size is actually .25 so you could use a half of the dot which would be .125 but then again 3 decimal places devided by 4 decimal places well you do the math. I enjoy MOA a lot better and size its in inches you can guess distances of items that you know your close to say a truck tire most factory truck tires are 31 inchs tall, thats .8611 when using the mildot formula, or 31 inches using MOA. Or you can put tha kabosh to all of this and go get a laser range finder! A small handheld caculator or palm pilot with software either programmed in or downloaded for trajectory and click values at certain distances. [ 09-07-2002: Message edited by: daveosok ] [/QUOTE]
