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. At 100 yards you can expect the bullet to impact between 2″ and 2.5″ below your point-of-aim.From approximately 13 yards out to approximately 89 yards the bullet’s impact will be within +/- 1″ of where you are aiming.22LR caliber AR15 style rifle, or AR15 with. 22LR AR-15 Style Rifle, 2.5″ Sight Height Above Bore: While there is a very slight penalty of higher apogee of flight with the 20-yard zero, you get almost one inch less drop at 100 yards.ĭedicated Or Converted.
While the 25 yard zero is very attractive, I would still recommend a 20-yard zero.Optic Mounted With Aiming Point ~1.5″ Sight Height Above Bore: If you will be shooting you rifle past 50 yards and out to 100 yards then you will be best served with a 10 yard zero.If the farthest distance that you will be shooting is 50 yards then you will be be served with a 12 yard or 15 yard zero.Given the accuracy of Norma USA 22 rimfire ammo, both TAC-22 and Match-22, I believe this October’s squirrel hunts will be more rewarding than ever.Spoiler: Traditional Factory “Iron Sights” ~.6″ Sight Height Above Bore: The satisfaction of making clean, deadly shots while barely disturbing the world around me is half my reward.

I don’t need hearing protection, so I’m free to listen as well as watch autumn's splendor coming down. The report of a 22 rimfire rifle is so slight that the woods return to normal within a minute or less if I minimize movement. My goal is to pick them off one by one, head shots only, until I have enough for a hearty stew. I might stalk a bit and call a bit, but this is my chance to relax and soak up the most glorious season. One of my most satisfying annual hunts is a quiet wait for tree squirrels in an October hardwood forest. That’s more than enough to terminate cottontails and various squirrels with head or chest hits. Stepping down to 1,000 fps drops 22 long rifle muzzle energy to about 100 f-p or slightly less. Compare that to the 1,150 f-p muzzle energy from a 40-grain 223 Remington load and you’ll begin to appreciate the difference. A 40-grain, 22 caliber lead bullet at 1,400 fps is considered hyper velocity for a 22 rimfire, yet it only kicks out about 180 foot-pounds of energy at the muzzle. In 22 rimfires I don’t worry about kinetic energy because there isn’t much of it in even the fastest 22 LR load.
