By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side.
It would help to avoid confusion. If you plan on shooting past 50 yards and out towards 100 yards I would recommend the 10-yard zero, then memorize the dope or make a range card, and practice at various distances to learn where the rifle will shoot. To fit it on a PDF file that's manageable, I've not includes some of the details (e.g. So far we have been showing the bullet traveling in a straight path. ( Log Out / Copyright © 2020 ShootersCalculator.comALL rights reserved. Also if you need it the BC for the Federal Ultra Match UM22 is not what is listed on their site at like .092. Keep in mind that technically you would have to aim 1/2″ low to hit exactly where you are aiming at 49-50 yards, but the red-dot in the TRS-25 (and most similar optics) is 3 MOA. The .223 Remington (5.56mm x 45) with a BC of .27 and a muzzle velocity of 3240 fps covers the distance in 99 milliseconds. The trajectory of the .22 LR cartridge is such that its maximum point blank range (MPBR) +/- 1 inch is about 85 yards. I had never really taken dedicated .22LR AR-15 rifles seriously until I was asked to help zero this rifle. To zero, you adjust the sights to raise the muzzle so that the path of the bullet would intersect the line of sight at your desired distance. From a distance of 13 yards from the muzzle, all the way out to approximately 89 yard, the point-of-impact of the bullet will never be +/- 1″ from point-of-aim. Your own rifle will probably shoot slightly differently. The manufacturer’s website for Federal Automatch gives a BC of .138. Recommendation: When using a rifle with an optic mounted so that the reticle is 1.5″ over the bore, and shooting Federal “Bulk Pack” ammunition, use a 20-yard zero setting. The 3 MOA dot will appear as 3″ wide at 100 yards. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. Did the old lot come in red plastic carriers in the box?
For hunting, I zero my .22 rifles at 25 yards, it will be point blank on a squirrel's head at the normal hunting distances I see.
Between 20 yards to 59 yards there is maximum rise of approximately 1/2″ over the point-of-aim (which will occur at 49 yards). Are you sure that your sabotaging kids didn’t turn mess with your sight adjustment knobs? At practice I had no trouble hitting all of them. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. The bullet is the same configuration ( I think) but I think the Ultra Match has more lube . The 50-yd zero extends that 2.00” window to 3 – 56 yds and the 1.00” window is 31 – 57 yds. So, to date I've accumulated almost 550 lines of data on my spreadsheet (see pic) and I've decided to share it for the first time if anyone has any interest. The 18" is a Ruger Precision Rimfire, and I could not mount the magneto in any satisfactory way. Thanks. Zero Range: 100 yd Chart Range: 500 yd Maximum Range: 1882 yd Step Size: 10 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 While I've been done with my little project for some time now, I continue to add data whenever I get hold of some LR ammo I've not ever used before. A friend recently acquired one of Colt’s .22LR M4 rifles made by Walther Firearms and asked if I would help zero the sights at the appropriate distance. There are several ballistics calculators available on the web which show charts and data as in the above picture. ), How To Zero The Kalashnikov AK-47 & AK-74, What Distance To Zero A Red Dot On An AK-47, AR-15 -- Methods For Zeroing A2 Type Sights, AR-15 -- Rear Sight & Optics With Front Sight Base, How To Zero H&K Sights -- HK-91/93 PTR-91 MP-5, AR-15 -- Mounting Removable Carry Handles. Then I thought that it might be useful for some of you here too. The CCI SV basically mirrors my drop chart. The relevant sight height is the rear sight, because your eye pupil and the aperture of the rear sight are the two points that define your line of sight. It might be worth creating some drop charts for the faster ammo, but only out to 50 yards unless people want to use four foot by four foot targets. I have only analyzed trajectories through 100 yards as the performance of the .22LR is anemic at best beyond that distance. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. I plan to bench check the 416 on wednesday when the temp is to be 30 degrees. For a better experience, please enable JavaScript in your browser before proceeding. 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”). 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). Of course, if there no gravity, the bullet would never come back down. I intended to do (and … Spread the word. Calculating the complex fluid dynamics of a bullet in flight is a challenge. Federal Ultra Match is covered under the Federal Match in the chart, I believe. Unfortunately the recent shortage of .22LR ammunition has made it hard to feed them if you didn’t already stockpile (hoard) .22LR ammunition. As with the Federal ammunition, simply put the red-dot over the intended point-of-impact (like a crown) and the bullet will drop right down where you want it. The shortage and rising prices of ammunition has made dedicated .22LR AR-15 rifles, and conversion kits for 5.56mm/.223 caliber AR-15 rifles very popular. You will be able to hit within a 1″ circle from just a few feet from the muzzle out to approximately 59 yards. Like in our analysis of the Federal ammunition we need to keep in mind that at 50 yards the 3 MOA dot of optic will appear as 1.5″ wide. ( Log Out / Just wanted to thank you for this post. The chart below shows the trajectories for the same round, same rifle, with sights adjusted for zeros at 25, 50 and 100 yards: The charts, and the data tables behind them, give us some interesting insights: The 25-yd zero gives us a very flat trajectory within a moderate range. Still, it is a good zero. The basic variables in calculating trajectory are muzzle velocity, ballistic coefficient, sight height above the bore, and the zero distance. Data on the ballistic coefficient of various bullets differ slightly among various sources. Good suggestions. In preparation for our first local long range precision .22 LR match this month, I found that many of the first time shooters had/have no idea what their dope is or should be. Additional variables can include wind speed and direction and elevation of the target relative to the rifle. Thanks -- G1 it is.. A 20-yard zero will see the bullet climb through point-of-aim at 20 yards and not drop back through until approximately 62 yards, during which time the bullet will only climb to a maximum of .56″ at 40 yards.
