There is an implication from many sources that MOA is used only for yards. Like all angular units of measurement, both imperial and metric can be used with both MOA and Mil-radians. Use 1.047-inch for imperial (yards) measurements. Use 2.91-cm for metric MOA's. Example; how many MOA's are in 300 meters? 3x2.91=8.73. Then divide this number into the ballistic drop for the number of MOA's to shoot at your desired range. Example: there are 50-cm of ballistic drop at a target distance of 300 meters. 50÷8.73=5.7273768613974. Round to 5.75 MOA for your turret adjustments. Let's use Mils to a 300 meter target. 3x10=30, 50÷10=5. Index 5-Mils on your turrets for a Mil scope. Use these numbers as constants for calculations. Yards: 1.047 for MOA, and, 3.6 for Mil-radians. Meters: 2.91 for MOA, and, 10 for Mil-radians. If you have a zero target in one inch squares use 0.3 Mils per inch. One click of a Mil turret is .36". Three each 0.36 units is 1.08", compare with a one MOA at 100 yards of 1.047". Calculate as, 1.08-1.047=0.033. As you can see there is only 0.033" of an inch difference. Less than the diameter of a bullet. A quick conversion factor to get a close approximation of a MOA from a Mil is 3.44. Example: I get a wind correction from a spotter of one Mil-radian to the right. I only need to index 3.5 MOA on the windage turret and shoot. The difference between Mils and Minutes is negligible. Generally the difference is less than the diameter of a bullet. So whichever you prefer, both Mils and MOA's can be used to get that deer to put meat in your freezer.
Makes sense from the way you put it. Don't you you need to subtract bullet drop from whatever your zero is OR whatever distance already shot at before you make the calculations?
@@roberth4475 : Concerning initial bullet drop. This bullet drop between parallel eye sight line to bore sight line is compensated for by the zeroing process. So that not an issue. The other question implies from one shot to the next. All calculations are from a 100 yards line, or, a 100 meters line. If your first shot is to 200 yards, and the next shot is to 360 yards. You either return to zero on your turret or subtract the amount of Mil's or MOA's that you used on the first shot from the Mil's/MOA's on the second shot. Then add that amount to whatever is on the turret. Example: a 200 shot needs 0.7-M-rad or 2.5-MOA to get to target. The second shot goes to 360 yards. Needing 2.3-Mil-rads or 8.3-MOA to get to a 360 yards target. So 2.3-0.7=1.6 Mils to add to the turret. Or, 8.3-2.5=5.8 MOA's on your turret. Since you don't have 5.8 MOA's index 5.75-MOA's. And shoot.
This short video is almost complete. It just needs to mention that sights and scopes move in MOA and the amount of MOA adjustment to the sights or scope describes the inches of movement it will make to bullet point of impact at target distance.
