At 50 yards, how far will a 10 MOA adjustment move the impact of the bullet in inches? Likewise, 1 MOA at 25 yards is 1/4″. Since MOA’s are “smaller” you need more of them than mils to make the same amount of adjustment. Zero this load so that the maximum bullet rise (mid-range trajectory) is 3 inches, and the average spitzer bullet will not fall 3 inches below the line of sight until it reaches 285 yards. If your scope adjusts in ¼ MOA clicks, then you will raise your desired point of impact 8.41 MOA / .25 MOA per click, or 34 clicks. At 500 yards you lose almost the entire height of a person and even at 200 yards the bullet is 3.2 inches below the point of aim. So, if you think in 1/2″ increments, and add up 10 of … Zero Range: 100 yd Chart Range: 2000 yd Maximum Range: 5926 yd Step Size: 100 yd: International Standard Atmosphere Altitude: Sea Level (0 ft) Barometric Pressure: 29.92 Hg Temperature: 59° F Relative Humidity: 50% Speed of Sound: 1116 fps Anyone know what my point of impact would be at 25 yards for a 50 yard zero ?? This generally happens because the added weight of a suppressor changes barrel harmonics. We are issued plain old 55 grain m-193. Point of Impact Shift A POI shift is a change in the bullet’s impact as a result of adding or removing a suppressor. This is a pretty flat trajectory, but the 30-yard zero looses its attractiveness as it drops down to 5.37″ below point-of-aim at 100 yards. Thus, when aiming center mass with a 12” standard at 300 yards one could expect that most rounds will impact within 4 to 5 inches from point of aim out to 250 yards. If 1 MOA at 100 yards is 1″, then at half the distance, 1 MOA is half as big and is 1/2″. If you zero that in at 50 yards, it will hit 4.2 inches low at 200 yards. Any load with a maximum point blank range (MPBR) of 285 yards can take a lot of game. The problem is my dept requires a 50 yard zero on all rifles. MOA = 36 / 4.28 hundreds of yards = 8.41 MOA. At 50 yards, that click will move the point of impact by one-half of one-quarter of an inch, or 1/8 th of an inch. I would sight in about 1.1 inches high at 50 yards or better yet, move out to 100 and try for 2.6 inches high, or even better yet, move to 200 yards … At 200 yards the figures are 2,342 fps and 1,827 ft. lbs. The 25-yard zero climbs over the point-of-aim at 25 yards and only reaches approximately 2/10″ before falling back through point-of-aim again at 50 yards. The situation is worse for a 62 grain .223 FMJ bullet since the higher weight also reduces muzzle velocity to around 2,700 FPS. The chart compares the absolute values of the deviations of the points of impact from the point of aim (0.0 inches on the graph being the point of aim/line of sight) for a 50-yard-zero and a 100-yard-zero, using Hornady 5.56 TAP T2 ammunition. Thus, a 25/300 meter or 36/300 yard zero may meet your requirement. 5 inches. The chart below illustrates the above concept. Still, it is a good zero. So, the simple answer is that with a 50 yard zero you will be good out to about 230 yards. I only have access to a 25 yard range before I qualify with this new set up. As a result, shorter and thicker barrels are less susceptible to change, but the truth is that there is no way to guarantee zero shift. Please I hope someone can help !
