Thread: Needing a new scope.

Well; here is a trick.
If you learn the subtensions of the inch / moa measurement from crosshair up or down to where the post thickens; - At 9* using a duplex the subtension at 100 yds is 2 1/"2- 3". At 100 yards if you zero using the upper junction of thin to thick you will be near ad gnats tit to dead on ifvyou hold crosshair on target at 200 yards. Then whenvyou have a target at 300yards you use the lower thin / thick junction; this being 3" / moa ( @ 100yards x 3) = 9" drop compensation to give you a poi in the boiler room. In other words these subtensions can take some of the guesswork out of estimating holdover when field shooting at a large targetcsuch ad broadside deer chest area. It's simple to figure the values for your own duplex reticle just by looking at a target gridded in inches / moa at 100 and noting the position of the various parts of the reticle on the grid.
