RIFLESCO PE The Vortex® EBR-1 MOA Reticle Designed to maximize long distance shooting and ranging abilities, the EBR-1 MOA reticle for the Viper®PSTTM 2.5–10x44 riflescope can be used to effectively determine ranges, holdovers, windage corrections and moving target leads. Ultra precision laser etching on the glass reticle ensures that minute of angle (MOA) specifications can be kept to the tightest tolerances possible.
RIFLESCO PE MOA Subtensions The EBR-1 reticle is based on minute-of-angle (MOA) subtensions. EBR-1 MOA Reticle Subtensions MOA measurements are based on degrees and minutes: 360 degrees in a circle, 60 Estimating MOA minutes in a degree for a total of 21,600 Although 1 MOA is very minutes. These angular measurements commonly corresponded to are used to estimate range and correct for 1 inch at 100 yards, this is bullet trajectory drop in riflescopes. 1 MOA not quite correct.
RIFLESCO PE Ranging MOA measurements are very effective for ranging using a simple formula. To use this formula, the shooter needs to know the size of the target or Example nearby object in inches. MOA Ranging Formula Target Size (Inches) x 95.5 = Range (Yards) Measured MOAs Using either the vertical or horizontal MOA scale, place the reticle on a target of known dimensions and read the number of MOAs spanned. You will obtain maximum accuracy in ranging by calculating exact MOA measurements.
RIFLESCO PE Elevation Holdovers Once the distance has been calculated using the EBR-1 MOA reticle, or a laser rangefinder, the EBR-1 can be used for rapid Example holdover correction for bullet drop of the cartridge being used. To get the most benefit out of the EBR-1 equipped riflescope, Vortex Optics highly recommends shooters learn their bullet drop numbers in MOAs rather than inches.
RIFLESCO PE Windage and Moving Targets The EBR-1 MOA reticle is highly effective when used for wind and moving target leads. Using the reticle for effective windage Example and moving target leads will require thorough knowledge of your weapons system’s ballistic performance under varying conditions and experience in reading wind strengths and target speeds. As in bullet drops, it is important for the shooter to learn a particular weapon’s windage/moving target corrections in MOAs rather than inches.
RIFLESCO PE Basic windage correction using drop line on reticle Basic moving lead correction When using the reticle for elevation correction rather than dialing, the When estimating moving target leads, the MOA marks on the center MOA marks on the center horizontal crosshair can still be used to help horizontal crosshair can be used. Estimating moving target leads will require visually reference windage corrections.
