Keeping accurate shooting data can help you put your first round exactly where you mean to land\u00a0it.<\/figcaption><\/figure>\n<p>For example, something we have seen firsthand is that a rifle barrel has a break-in period where it has to warm up. If you have a brand new rifle, it will shoot slower than it\u2019s supposed to guarantee. We recommend putting 200 rounds through your rifle before you can consider its muzzle velocity to be consistent. The rifling in the barrel has a break-in period where it will get faster and faster velocity until it breaks through that new threshold.<\/p>\n<div class=\"newsletter inline\">\n<div class=\"newsletter-inner\">\n\t\t\t\t<img decoding=\"async\" style=\"display: none;\" class=\"logo-tal-icon\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/themes\/thearmorylife\/img\/logo-tal-tm-icon.svg\" alt=\"\"\/><\/p>\n<p><strong>Live The Armory Life.<\/strong> The latest content straight to your inbox plus an automatic entry to each of our <a class=\"ajax-giveaways\" href=\"https:\/\/www.thearmorylife.com\/giveaways\/\"><strong>monthly gun\u00a0giveaways!<\/strong><\/a><\/p>\n<\/p><\/div>\n<\/p><\/div>\n<p>The issue is that not knowing your true muzzle velocity leaves a hole in a ballistic computer\u2019s equation. There are devices to help you measure this so you can fill in the gap, however. That is just one way that data from a ballistic computer may mislead you.<\/p>\n<h2>Solutions<\/h2>\n<p>So how do you fix this and get faster than the computer? The only solution is to get out, shoot some rounds and do something we call truing your data. You will need to build your own DOPE for your rifle and your ammunition of choice. Those two things need to be as consistent as possible, so make sure you stick with the exact same brand of ammo. If it is in the same lot number, then that\u2019s even better.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" class=\"wp-image-34868\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope-800x533.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope-400x267.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope-768x512.jpg.webp 768w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"\/><img decoding=\"async\" loading=\"lazy\" width=\"1400\" height=\"933\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope.jpg\" alt=\"shooting the rifle to check your scope dope\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope-800x533.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope-400x267.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/shooting-the-rifle-to-check-your-scope-dope-768x512.jpg 768w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption>A computer cannot compensate for all possible variables in your shooting. You need to get out and get rounds down range to true your\u00a0DOPE.<\/figcaption><\/figure>\n<p>Where do you start truing your data? Zero your gun at 100 yards, have a good zero you are confident in, and shoot an actual group of at least five to six rounds with this zero to confirm it. Next, Grant recommends going and shooting with your cartridge at a distance just before it starts to exit its supersonic flight and enter transonic flight into subsonic flight.<\/p>\n<p>For the 6.5 Creedmoor Model 2020 Waypoint we have on hand, we shot at 700 yards for this purpose. We took a spotter who watched through the spotting scope and walked our round into the target one miss at a time, starting with the computer\u2019s DOPE until we hit the target. When our point of impact hits our point of aim, we input that MIL setting into the computer to true the data. This should auto calculate the rest of the distances on your computer\u2019s DOPE.<\/p>\n<figure class=\"wp-block-image size-full\"><picture loading=\"lazy\" class=\"wp-image-34869\"><source type=\"image\/webp\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book.jpg.webp 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book-800x533.jpg.webp 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book-400x267.jpg.webp 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book-768x512.jpg.webp 768w\" sizes=\"(max-width: 1400px) 100vw, 1400px\"\/><img decoding=\"async\" loading=\"lazy\" width=\"1400\" height=\"933\" src=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book.jpg\" alt=\"American Snipers Data Book\" srcset=\"https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book.jpg 1400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book-800x533.jpg 800w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book-400x267.jpg 400w, https:\/\/www.thearmorylife.com\/wp-content\/uploads\/2022\/09\/American-Snipers-Data-Book-768x512.jpg 768w\" sizes=\"auto, (max-width: 1400px) 100vw, 1400px\"\/>\n<\/picture><figcaption>As you work out your DOPE, make sure you keep accurate records. As you change aspects of your shooting \u2014 such as the load shot \u2014 you need to record additional\u00a0data.<\/figcaption><\/figure>\n<p>Now your DOPE is perfect and you will never miss! Right? Wrong. Now you need to work your way back in at some other distances and try testing it farther out. But you should be much closer to fully understanding your rifle now.<\/p>\n<p>After you have trued your data further, Grant suggests writing it down, typing it up, printing it off and carrying it with your long distance gear. Now, in theory, who even needs a computer if you\u2019re shooting around the distances you have mapped? That\u2019s not entirely true, so don\u2019t toss your ballistic computer in the trash just yet. The computer still serves a purpose, and now that you have trued the data it will be that much more accurate.<\/p>\n<p><em>Editor\u2019s Note: Be sure to check out\u00a0<\/em>The Armory Life<em>\u00a0Forum, where you can comment about our daily articles, as well as just talk guns and gear.
