<p>You don&#8217;t hear much about PacNor barrels in long-range competition, but FORUM member Wes J (aka P1ZombieKiller), proved that they can shoot &#8220;lights-out&#8221; in a rig assembled by a talented gunsmith. A few seasons back, Wes decided to upgrade a 6mmBR for mid-range benchrest and varmint matches. Wes tells us: &#8220;Since I restocked my 6BR &#8230; I have not had a chance to shoot it much since I have been playing the 100-200 game. I decided to take it out and do some playing at 500 yards. I have to give some serious props to my buddy (and fellow FORUM member) &#8216;PREACHER&#8217; who did the chambering and barrel work for me. He can certainly make a gun shoot good. The barrel is a PacNor 1:8&#8243; twist. My load was 105gr Berger VLDs pushed by 29.6 grains of Varget.&#8221; The five-round, 500-yard group shot by Wes J with his 6BR, measured just 1.240&#8243;, as measured by <a href="https://ontargetshooting.com/" target="_blank">OnTarget software</a>. Now that&#8217;s one accurate rig!</p>
<p><font size="2"><b>Five by Five &#8212; 5-Shot Group at 500 Yards, 1.240&#8243;, 0.237 MOA</b></font><br />
<img src="https://accurateshooter.net/Blog/zombie02.jpg" alt="6BR 6mmBR Preacher PacNor"></p>
<p>This Editor knows something about the potential of a PacNor barrel. I have a 3-groove stainless PacNor SuperMatch on a Savage-actioned 6BR. This barrel shoots honest quarter-MOA in calm conditions, and it cleans up super-easy. The interior finish is so good, I&#8217;ve never had to brush the bore or use abrasives, and after 750 rounds it shoots as well as ever. I attribute the easy cleaning to the fact the lands in a PacNor 3-groove are wide and flat, so they are gentle on bullet jackets. I think accuracy is helped by the fact that my PacNor runs on the tight side (0.236 land dimension) with a good amount of choke. That works well with the 105gr Lapua Scenars and 103gr Spencers I like to shoot. You can read more about my rifle, nick-named the &#8220;Poor Man&#8217;s Hammer&#8221;, in this <a href="http://www.accurateshooter.com/guns-of-week/poormanshammer/" target="blank">Feature Article</a> from our archives. On one particularly calm day, in the hands of my friend (and ace trigger-puller) Joe Friedrich, the Poor Mans&#8217; Hammer put 3 shots in under 0.200&#8243; (measured center to center) at TWO Hundred yards. If you get a good one, PacNor three-grooves can definitely shoot.</p>
<blockquote><p><img align="right" hspace="6" src="https://accurateshooter.net/Blog/Eleygroupx200.jpg" alt="OnTarget Software"><strong>Target Measurement with OnTarget Software</strong><br />
We used <a href="https://ontargetshooting.com/" target="_blank">OnTarget software</a> to measure the 5-shot group in the target above. This easy-to-use software is very repeatable, once you get a feel for plotting the shots. The latest On Target v2.25 Precision Calculator is FREE for a 15-day evaluation period. If you like it (and you will, trust us) there&#8217;s a modest $11.99 registration fee to activate the program. In addition to group size (in inches), OnTarget plots distance to aiming point, and the software automatically calculates the group&#8217;s vertical height, horizontal dispersion, average to center (ATC), and group size in MOA.</p>
<p>You can run a measurement on a scanned target or a photo of a target. You&#8217;ll need some known reference to set the scale correctly. The target above had a one-inch grid so it was easy to set the scale. Once you&#8217;ve set the scale and selected bullet diameter and target distance, you simply position the small circles over each bullet hole and the <a href="https://ontargetshooting.com/" target="_blank">OnTarget software</a> calculates everything automatically, displaying the data in a data box superimposed over the target image. To learn more about OnTarget Software, read AccurateShooter.com&#8217;s <a href="https://www.accurateshooter.com/technical-articles/ontarget-software-measures-groups/" target="_blank">OnTarget Product Review</a>. This article covers all the basics as well as some advanced &#8220;power user&#8221; tips. NOTE: Since the review was written, On Target has updated the software, and the free version now has a time limit.</p></blockquote>
