NOTE: <em>There are ten (10) shots in the group, but for simplicity we are only displaying five (5) shot circles. Adding more circles won’t change the measurement because the two most distant shots, which determine group size, ARE included.</em></p>
<p>What kind of 200-yard accuracy can you get in an enclosed, underground test range? Would you believe 0.162 MOA at 200 yards with a .338? Have a look at these test targets from <a href="https://www.sierrabullets.com/" target="_blank">Sierra Bullets</a>. Like most bullet manufacturers, Sierra does live-fire bullet testing to ensure that Sierra projectiles perform as promised, with repeatable accuracy. Sierra tests bullets in its own <strong>underground test complex</strong>. Sierra&#8217;s 300-meter test range is the longest, privately-owned underground bullet test facility in the Western Hemisphere.*</p>
<p><img src="https://accurateshooter.net/pix/sierratun1903.jpg" alt="Sierra Bullets indoors testing barrels"></p>
<p>Day in and day out, various bullet types are tested using a big collection of barreled actions. These barreled actions are clamped in stout, return-to-battery test fixtures. These big, heavy test fixtures provide near-perfect repeatability (with no human-induced holding or aiming errors).</p>
<p><b>Sierra Bullets 10-Shot Groups at 200 yards</b><br />
Check out these 10-shot test groups shot at the Sierra Test Range at 200 yards. Note that the numbers listed on each sample are actual measurements in inches. To convert to MOA, cut those numbers in half (to be more precise, divide by 2.094, which is 1 MOA at 200 yards). For example, the 0.340&#8243; middle group works out to 0.162 MOA at 200 yards.</p>
<p><img src="https://accurateshooter.net/Blog/sierratest2op.jpg" alt="Sierra Bullets indoors testing barrels"></p>
<blockquote><p><img class="alignright" hspace='6' src="https://accurateshooter.net/pix/sierrascan1501.jpg" alt="Sierra Bullets indoors testing barrels"><b>Scan-Verified 0.162 MOA Accuracy at 200 Yards</b><br />
To verify the accuracy of Sierra&#8217;s measurements, we measured the middle (.338 caliber) 10-shot group with our On-Target Group Measurement software. We registered a group size reading of 0.339&#8243; &#8212; within one-thousandth of the Sierra measurement. The calculated group size in MOA (Minute of Angle) is 0.162.</p>
<p>That&#8217;s amazingly good for ten rounds of big .338 caliber bullets. A FIVE-shot <strong>0.162 MOA group</strong> at 200 would be considered excellent at any benchrest match. But remember this target has TEN shots. The current, one-target <a href="https://internationalbenchrest.com/records/group#smallest-10-shot-groups-by-class-records" target="_blank">IBS world record for ten shots at 200 yards</a> is 0.245&#8243;, set by Ed Watson in 1999.</p></blockquote>
<p><b>Bevy of Barreled Actions for Bullet Testing</b><br />
Sierra Bullets uses dozens of barreled actions for testing bullets in its enclosed, 200-yard test range. Each barrel has its own logbook to track the barrel’s usage.</p>

*Even Longer Test Tunnels Exist in Europe: At Stadeln in Germany, RWS (now part of RUAG) owns a 500 meter tunnel (above ground level) which has existed for decades. In Thun, Switzerland, RUAG has a fully-instrumented 500 meter underground tunnel. Near Ulm, Germany, there is a 5-lane 300 meter underground shooting range that is open to the public.</p>

<p>Here is some useful information for FFLs and gun dealers. The NSSF now offers a special online training course: “Completion of the ATF Form 4473 2023 Edition”. NSSF members can access this web-based course via the <a href="https://www.nssf.org/membership/nssfs-shot-university-online/" target="_blank">SHOT University Online</a> education center.</p>
<p>Why do you need to learn about the latest <a href="https://atf-form-4473.pdffiller.com/" target="_blank">ATF Form 4473</a>? Well the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) revised the form in December 2022 to reflect new statutory requirements imposed by the Bipartisan Safer Communities Act, the NICS Denial Notification Act, and the ATF Final Rule 2021R-05F. Use of the latest December 2022 edition Form 4473 is mandatory as of April 1, 2023.</p>
<p><iframe src="https://player.vimeo.com/video/467457461?h=af11ba1a53&#038;color=3e516b&#038;title=0&#038;byline=0&#038;portrait=0" width="600" height="340" frameborder="0" allow="autoplay; fullscreen; picture-in-picture" allowfullscreen></iframe><br />
<a href="https://vimeo.com/467457461" target="_blank">Completing Form 4473 | NSSF SHOT University Online</a> from <a href="https://vimeo.com/nssf" target="_blank">NSSF</a> on <a href="https://vimeo.com" target="_blank">Vimeo</a>.</p>
<p>This training series reviews key elements of the 6-page Form 4473, as well as tips for identifying and correcting common errors made by both buyers and sellers. The training series has three segments:</p>
<p><strong>Module 1: Overview of Form 4473<br />
Module 2: Completing Form 4473, Sections A-B<br />
Module 3: Completing Form 4473, Sections C-E</strong></p>
<blockquote><p>The NSSF states that &#8220;All FFL counter salespeople, compliance officers, records keepers, and license holders should consider these SHOT University Online courses to be vital training to enhance FFL training and help reduce errors when using the new form.&#8221;</p></blockquote>
<p>FFLs can order the December 2022 edition of the Form 4473 through the ATF Distribution Center, and the form is available for download at <a href="https://www.atf.gov/" target="_blank">www.atf.gov</a>. <strong>Use of the December 2022 edition is mandatory beginning April 1, 2023.</strong> At that time, use of the May 2020 edition must be discontinued. The new Form 4473 and continuation sheets are <a href="https://www.atf.gov/distribution-center-order-form" target="_blank">available from the ATF</a> in both English and Spanish. A <a href="https://atf-form-4473.pdffiller.com/" target="_blank">PDF version</a> is offered online also.</p>
<p>SHOT University Online and the “Completing the Form 4473 2023 Edition” series are available as part of NSSF member benefits. For this and other instructional offerings, paid NSSF members should log in at <a href="https://www.nssf.org/membership/nssfs-shot-university-online/" target="_blank">SHOT University’s home page</a> with their username and password, then click on the course of their choice.</p>

NOTE: <em>There are ten (10) shots in the group, but for simplicity we are only displaying five (5) shot circles. Adding more circles won’t change the measurement because the two most distant shots, which determine group size, ARE included.</em></p>
<p>What kind of 200-yard accuracy can you get in an enclosed, underground test range? Would you believe 0.162 MOA at 200 yards with a .338?
