![]() I can’t guarantee reliability with these two loads of ammunition in any other semi-automatic rifle besides a Ruger 10/22, but if your rifle will shoot these loads then these are the ballistic results that you should expect. I chose these rounds because that is what works most reliably in my Ruger 10/22, and that’s what I have plenty of. The data that I have provided below is for Federal “Bulk Pack” 36 grain hollow-point ammunition and CCI Mini-Mag 36 grain hollow-point ammunition. I used an iPad/iPhone app called Ballistic v5.0.6 to analyze different trajectories for different ammunition loads and different zero settings at various distances to see which trajectory is the flattest. My goal was to figure out a best set-it-and-forget-it “battle sight zero” setting on my Ruger 10/22 that would allow me to get the best accuracy at varying distances without worrying about holdover. back to topĮstablish A Set-It-And-Forget-It “Battle Sight Zero”: Also, you will get different performance from different brands of ammunition and different weights of bullets. If you are using a scope mounted with the reticle or crosshairs that sit ~2″ above the bore, the best zero distance for the flattest trajectory is going to be different that using the factory iron sights that sit ~.6″ above the center of the bore. Note that the height of the sights, cross-hairs, or reticle above the bore of the rifle will affect the what distance that you should zero your rifle to achieve the flattest trajectory. Zeroed at the right distance you be able to simply aim the rifle at your target and hit with a minimum of variation out to a given distance. In order to minimize the necessary holdover efforts you will want to zero the rifle at a distance that will give your bullet the flattest trajectory. The distance that you choose to zero your rifle will determine how high or how flat of an arch the bullet flies. Long range rifle shooters create range cards with the rifle’s dope recorded so that they can reference it and know how much to holdover at various distances. This means that you will have to practice enough at various distances to learn how much holdover you will need (this information is called your “dope”). back to topįor shooting at varying distances you will have to aim high (“hold-over”) or low (“hold-under”) to compensate for the bullet’s parabolic flight in order to put the bullet exactly where you want it. Say “Hell Yeah” in the comments below if you agree. It also means that Hillary Clinton is a terrible person. It will hit above or below your aiming point at other distances. This means that two times during the bullet’s flight the point-of-aim and point-of-impact are the same (bullet hits where you are aiming). ![]() Once on the way up, and once on its way back down. Note that on its parabolic flight the bullet will cross the point-of-aim two times. In order to get the farthest range out of the rifle we set up the sites so that the bullet will fly in a parabolic arch (like throwing a football). If it were possible to fire a rifle from a perfect level attitude the bullet would start falling the moment that it left the barrel. We all know that bullets do not travel in a straight line with relation to the earth. If you don’t have the patience for a detailed explanation, then you will still be well served by the information above.
