<p>Rimfire is hot now. Across the nation, .22 LR rimfire disciplines are now the fastest growing types of rifle competition. And with today&#8217;s featured rig, the Competition Machine (Eliseo) <a href="https://eliseorifles.wordpress.com/2020/05/11/universal-match-rimfire-rifle/" target="_blank">Universal Match Rimfire Rifle</a> (UMRR), you can shoot a variety of matches &#8212; NRA rimfire, NRL22, NRL22X, PRS Rimfire, local silhouette-style steel matches, even local rimfire benchrest matches (with a bag-rider fitted up front).</p>
<p>Compared to shooting centerfire, rimfire shooting is much less costly. You can get pretty good match ammo for under $8.00 per box. That works out to just 16 cents per round. Compare that to $1.60 or more per round for handloaded centerfire ammunition (counting powder, bullet, primer and brass). And you don&#8217;t have to deal with shortages of your preferred powder or primers, or spend hours hand-loading. With rimfire, just open your .22 LR ammo box, load your magazine, and shoot.</p>
<h2>Versatile, Accurate, Affordable &#8212; Universal Match Rimfire Rifle</h2>
<p>If you&#8217;re a Palma shooter and want to shoot rimfire with a rifle with identical ergonomics and &#8220;feel&#8221; as your centerfire tubegun, Gary Eliseo&#8217;s new Universal Match Rimfire Rifle (UMRR) is your logical choice. Or if you are looking for a high-quality bolt-action chassis rifle for NRL22 (rimfire tactical) competition, this is a great option. Running a smooth Tikka T1x action, the UMRR offers match-grade performance at an attractive price &#8212; <a href="https://eliseorifles.wordpress.com/2020/05/11/universal-match-rimfire-rifle/" target="_blank">$1950.00 for the Sport-Target model</a> with 20&#8243; Tikka factory barrel.*</p>
<p><b>The Tikka T1x action is a smooth, short-throw action that cycles quickly and easily:</b><br />

<p>Gary Eliseo, head honcho of <a href="https://www.gotxring.com/" target="_blank">Competition Machine</a> in Arizona, explained the features of the UMRR: &#8220;Our Universal Match Rimfire Rifle system has all the features of its big brother the Universal Match Rifle System (UMRS) and will accept all the same accessories and attachments. The rimfire UMRR is identical in size to the centerfire version so it&#8217;s possible to have your centerfire and rimfire rifles set up exactly alike.&#8221; That&#8217;s ideal for guys who compete in both centerfire and smallbore matches, and likewise it is ideal for cross-training using lower-cost rimfire ammo.</p>
<p><img src="https://accurateshooter.net/pix/umrrcss2fix.jpg" alt="Gary Eliseo Rifles Competition Machine UMRR Universal Match Rimfire Rifle"></p>
<p>The UMRR is built around the excellent <a href="https://www.sako.global/series/tikka-t1x" target="_blank">Tikka T1x platform</a>. Gary notes: &#8220;We have <strong>accurized and tuned the T1x</strong> to give the best possible performance from factory barrel and trigger. The UMRR can also be customized with a high-end match barrel and trigger. By just changing the attachments, the UMRR can be used in multiple shooting disciplines like NRL22 and NRA rimfire competitions.&#8221; Gary also noted that Tikka recently updated the T1x bolt and magazine for improved feeding and extraction. See video below.</p>
<p><big><b>Sport-Target UMRR Shows Excellent Accuracy with Factory Barrel</b></big><br />
Eliseo confirms that the Sport-Target UMRR with factory Tikka barrel and trigger is easily capable of <strong>sub-MOA precision</strong>. Check out those five-shot groups shot at 50 yards. The smallest group (.210&#8243;) works out to 0.40 MOA, while the largest group (0.39&#8243;) is 0.74 MOA. Remember this is with Tikka factory barrel!</p>
<p><img src="https://accurateshooter.net/pix/umrrcss3.jpg" alt="Gary Eliseo Rifles Competition Machine UMRR Universal Match Rimfire Rifle"><br />
<i>The Sport-Target UMRR with factory Tikka barrel and trigger is capable of sub-MOA precision.</i></p>
<p>The Sport-Target version uses the factory 20″ Tikka barrel with threaded muzzle that has been set back and re-chambered so the bullet will engrave the rifling, which increases the precision of the rifle significantly. The excellent Tikka trigger is tuned to a pull weight of one pound. Overall the UMRR is a great choice as an XTC/LR prone trainer or NRL competition rifle at very reasonable cost.</p>
<h2>Superb Accuracy from UMRR Match-Target Model</h2>
<p>The <a href="https://eliseorifles.wordpress.com/2020/05/11/universal-match-rimfire-rifle/" target="_blank">Match-Target version</a> comes with a top of the line Benchmark match barrel and Eley match chamber with the muzzle configured for your application to accept a front sight, tuner, or threaded, there are several aftermarket single-stage or two-stage match triggers available. Current Eliseo Rifles price for the <a href="https://eliseorifles.wordpress.com/2020/05/11/universal-match-rimfire-rifle/" target="_blank">UMRR Match-Target is $2650.00</a>.*</p>
<p><img src="https://accurateshooter.net/pix/umrr22x3.jpg"  alt="Gary Eliseo Rifles Competition Machine UMRR Universal Match Rimfire Rifle"></p>
<p>The Match Target with Benchmark match barrel is capable of competing at the highest level. Shown above are 50-meter sling targets and Lapua 50-meter test center results. The bottom box shows 20 shots with a superb 10.52 average score.</p>
<h2>Updates from Tikka Improve the T1x Action and Magazine</h2>
<p>Gary noted that Tikka has updated the Tikka bolt and magazine to improve feeding and extraction. Tikka replaced a wire-type system with a solid ejector element in the magazine. Gary says that improves the reliability of both feeding and extraction. Watch the video to see how this works.</p>
<p><center><iframe width="400" height="500" src="https://www.youtube.com/embed/gfY0-qz1UzM" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></center></p>
<h2>Centerfire Accesories Will Work on UMRR</h2>
<p>Gary notes that <strong>all the centerfire UMRS attachments will fit the UMRR</strong>, including handstop, rear balance weights, Picatinny scope rail, ARCA accessory rail, rear bag-rider, bipod mount, and front bag riding attachments. This easy adaptability makes the UMRR a true multi-discipline system for smallbore matches, NRL22/PRS rimfire competition, and cross-training.</p>
<p><img src="https://accurateshooter.net/pix/umrrcss4.jpg" alt="Gary Eliseo Rifles Competition Machine UMRR Universal Match Rimfire Rifle"></p>
<h2>Adapt the UMRR Easily to Multiple Shooting Disciplines</h2>
<p>The UMRR can be easily configured for NRL, PRS, or NRA rimfire competitions by just changing the attachments. The UMRR is built on the excellent Tikka T1x barreled action that&#8217;s been accurized and bonded into the UMRR chassis system. Gary says the UMRR feeds .22 LR rounds flawlessly from the Tikka 10-round magazine, especially with the new, improved magazines. The UMRR is currently available in two basic configurations, both of which can be customized to your specifications.</p>
<p><big><strong>Two Versions &#8212; Sport-Target and Match-Target</strong></big><br />
The Sport-Target version of the UMRR uses the factory 20&#8243; Tikka barrel with threaded muzzle. Gary can tune the excellent Tikka T1x trigger down to a pull weight of around one pound, though for tactical work he says you may want to leave it stock. Gary tells us the Sport-Target is a great choice as an XTC/LR prone trainer or NRL22 competition rifle.</p>
<p><big><b>Match Target UMRR with Benchmark Custom Barrel</b></big><br />
The Match-Target version comes with a top-of-the-line Benchmark match barrel and Eley match chamber with the muzzle configured for your application to accept a front sight, tuner, or suppressor. There are several aftermarket single-stage or two-stage match triggers available.</p>
<p><img src="https://accurateshooter.net/pix/umrr22x4x600.jpg" alt="Gary Eliseo Rifles Competition Machine UMRR Universal Match Rimfire Rifle"></p>
<blockquote><p><b>Tikka T1x &#8212; Quality Rimfire Technology from Finland</b><br />
Gary Eliseo&#8217;s impressive UMRR is based on the smooth, reliable Tikka T1x rimfire action shown below. Note the nice craftsmanship of action, bolt, mag system, and trigger group. There is an extensive review of the T1x (.22 LR version) on our friend Jonathan Ocab&#8217;s <a href="https://www.ocabj.net/tikka-t1x-mtr-22lr-rifle-review/" target="_blank">Ocabj.net website</a>.</p></blockquote>

<p>Editor&#8217;s NOTE: The key to keeping an AR running reliably is proper lubrication (in the RIGHT places), and regular cleaning of the bolt carrier and bolt, including ejector recess and extractor recess. The majority of non-functioning ARs we&#8217;ve seen had gunk, lube, carbon, and brass shavings in those recesses.</p>

<p>Most of us own a .223 Rem rifle. Now, thanks to our friends at <a href="https://rifleshooter.com/2014/04/223-remington5-56-nato-velocity-versus-barrel-length-a-man-his-chop-box-and-his-friends-rifle/" target="_blank">Rifleshooter.com</a> we can assess exactly how velocity changes with barrel length for this popular cartridge.</p>
<p><a href="https://rifleshooter.com/2014/04/223-remington5-56-nato-velocity-versus-barrel-length-a-man-his-chop-box-and-his-friends-rifle/" target="_blank">Rifleshooter.com</a> performed an interesting test, cutting the barrel of a .223 Rem rifle from 26&#8243; all the way down to 16.5&#8243;. The cuts were made  in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .223 Rem/5.56 ammo were chron&#8217;d at each barrel length. The Rifleshooter.com team that conducts these tests has a full-service gun shop, 782 Custom Gunworks &#8212; visit <a href="https://782guns.com" target="_blank">782guns.com</a>.</p>

<p><big><b>Test Barrel Lost 25.34 FPS Per Inch (.223 Rem Chambering)</b><br />
How much velocity do you think was lost, on average, for each 1&#8243; reduction in barrel length? The answer may surprise you. The average speed loss of the four types of .223/5.56 ammo, with a 9.5&#8243; shortening of barrel length, was 240.75 fps total (from start to finish). That works out to an <strong>average loss of 25.34 fps per inch</strong>.</big></p>

The testers described their procedure as follows: &#8220;Ballistic data was gathered using a Magnetospeed barrel-mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 45.7&deg; F.&#8221;</p>

Rifleshooter.com has performed barrel cut-down tests for many other calibers/chamberings including <a href="https://bulletin.accurateshooter.com/2019/05/6mm-creedmoor-how-many-fps-will-a-shorter-barrel-cost-you/" target="_blank">6mm Creedmoor</a>, <a href="https://bulletin.accurateshooter.com/2019/01/rifleshooter-com-308-win-barrel-cut-down-velocity-test/" target="_blank">.308 Winchester</a>, and <a href="https://bulletin.accurateshooter.com/2019/08/cutting-338-lm-barrel-from-30-to-17-velocity-loss-revealed/" target="_blank">.338 Lapua Magnum</a>.

<p><b>Much Different Results with 6mmBR and a Longer Barrel</b><br />
The results from Rifleshooter.com&#8217;s .223/5.56 test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33&#8243; to 28&#8243; we only lost about <strong>8 FPS per inch</strong>. Obviously this is a different cartridge type, but also our 6mmBR barrel end length was longer than Rifleshooter.com&#8217;s .223 Rem start length. Velocity loss may be more extreme with shorter barrel lengths. And, of course, different cartridge types and powder/bullet combinations will yield different results.</p>

When you ask other well-known handgun smiths whom they would rank among the very best, Liebenberg is a consensus pick. And Paul&#8217;s work is in high demand. There is a multi-year-long waiting list for his custom pistols, mostly built on 1911-platforms.</em></p>
<p>Some years back, Liebenberg shared his pistol building/tuning knowledge in a professional DVD from <a href="https://panteao.com/" target="_blank">Panteao Productions</a>. In that DVD, Liebenberg demonstrated the procedures he employs when crafting a custom 1911 pistol. The DVD&#8217;s topics covered included: fitting barrel and barrel bushing, installing grip safety and thumb safety, installing and tuning the trigger, installing and tuning extractor and ejector, relieving the mag well, undercutting the trigger guard, lowering the ejection port, and much more. Below are two YouTube videos that cover highlights from the DVD.</p>
<p><img class="alignright" hspace="6" src="https://accurateshooter.net/Blog/liebenbergdvd03.jpg" alt="Liebenberg DVD"><b>40+ Years Expertise</b><br />
A trained industrial designer from South Africa, Paul Liebenberg was a member of the World Champion South African Practical Pistol Shooting Team. An NRA High Master and four-gun firearms instructor, Paul has competed successfully in many shooting disciplines.</p>
<p>In 1983 Liebenberg immigrated to the USA and joined Pachmayr Gun Works in Los Angeles where he rose to manage the Custom Gun Shop. In 1985 he opened Pistol Dynamics to build high-end 1911 competition handguns and Pachmayr pistols on contract to that company. Today <a href="https://www.pistoldynamics.com/" target="_blank">Pistol Dynamics</a> is in Florida where Paul continues to build high-end 1911 pistols.

<h2>How Krieger Builds Barrels</h2>
<p>This video shows the process of cut-rifled barrel-making by <a href="https://kriegerbarrels.com/" target="_blank">Krieger Barrels</a>, one of the world&#8217;s best barrel manufacturers. Krieger cut-rifled barrels have set numerous world records and are favored by many top shooters. The video show the huge, complex machines used &#8212; bore-drilling equipment and hydraulic riflers. You can also see how barrels are contoured, polished, and inspected.</p>
<p>For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.</p>

<blockquote><p><img src="https://accurateshooter.net/Blog/cutriflemach03.jpg" alt="Pratt &#038; Whitney Cut rifling hydraulic machine"></p>
<p>&#8220;At the start of World War Two, Pratt &#038; Whitney developed a new, &#8216;B&#8217; series of hydraulically-powered rifling machines, which were in fact two machines on the same bed. They weighed in at three tons and required the concrete floors now generally seen in workshops by this time. Very few of these hydraulic machines subsequently became available on the surplus market and now it is these machines which are sought after and used by barrel makers like John Krieger and &#8216;Boots&#8217; Obermeyer. In fact, there are probably less of the ‘B’ series hydraulic riflers around today than of the older ‘Sine Bar’ universal riflers.&#8221; &#8212; Geoffrey Kolbe, Border Barrels.</p></blockquote>

Do you know what operations are done to an action during the blueprinting process? To help you understand, gunsmith Bill Marr of <a href="https://rifleshooter.com/" target="_blank">RifleShooter.com</a> has created a helpful article showing a <a href="https://rifleshooter.com/2013/02/blueprinting-a-remington-700/?" target="_blank">Rem 700 blueprinting job</a> start to finish. This article spotlights how the procedures can be done with manual tools. Bill, who runs <a href="https://782guns.com/" target="_blank">782 Custom Gunworks Ltd.</a>, can also perform many of these operations with modern automated machinery. In fact, Bill has written a follow-up article on <a href="https://rifleshooter.com/2014/12/blueprinting-truing-a-remington-700-action/" target="_blank">Truing a Rem 700 receiver with a Lathe</a>.</p>

<h2><a href="https://rifleshooter.com/2014/12/blueprinting-truing-a-remington-700-action/" target="_blank">READ Blueprinting Rem 700 Action with Lathe Article HERE &#187;</a></h2>
<p>Bill explains: &#8220;Blue-printing, or truing a rifle action, ensures the receiver face, threads, lugs, bolt lugs, and bolt face are square to the center line of the receiver.&#8221; In Bill&#8217;s <a href="https://rifleshooter.com/2013/02/blueprinting-a-remington-700/?" target="_blank">informative article</a>, Bill shows how he blueprints a Remington 700 short action receiver with .308 Win bolt face. He covers the following procedures step by step:</p>
<h3>Action Disassembly<br />
Ream Minor Diameter of Receiver Threads<br />
Square the Receiver Lugs<br />
Square the Face of the Receiver<br />
Lap the Bolt Lugs<br />
Square the Bolt Face</h3>
<p>Bill employed a variety of tools from <a href="https://www.brownells.com/">Brownells</a> to complete the blueprinting job, including: Remington 700 Armorer&#8217;s Kit; Manson Receiver Accurizing Kit; Bolt Lapping Kit; Bolt Face Truing Tool; Manson Receiver Ring Facing Cutter; Multi-Vise with Jaw Pads; Silicone Carbide Abrasive; and Do-Drill Cutting Oil.</p>
<h2>Highlights from the Rifleshooter.com article:</h2>
<h3>1. Chasing the Threads</h3>
<p>We use the bushings to guide the receiver tap. This chases the threads and ensures they are square.</p>
<p><img src="https://accurateshooter.net/pix/marr1902.jpg" alt="Bill Marr Rifleshooter.com truing Remington Rem 700 action accurizing"></p>
<h3>2. Truing the Receiver Face</h3>
<p>Using the receiver facing tool, the front of the receiver is trued.  The tool is placed over the tap and turned by hand. We used Do Drill to lubricate it.</p>
<p><img src="https://accurateshooter.net/pix/marr1905.jpg" alt="Bill Marr Rifleshooter.com truing Remington Rem 700 action accurizing"></p>
<h3>3. Lapping the Lugs</h3>
<p>The bolt lapping tool screws into the front of the action and applies rearward pressure on the bolt face. A little bit of lapping compound is placed on the front of the receiver lugs. The bolt handle is then raised and lowered repeatedly. Note &#8212; it is critical that we do not get any lapping compound on any other surfaces.</p>
<p><img src="https://accurateshooter.net/pix/marr1903.jpg" alt="Bill Marr Rifleshooter.com truing Remington Rem 700 action accurizing"></p>
<h3>4. Truing the Bolt Face</h3>
<p>On this bolt, the central part of the bolt face was low. After the truing operation, this Rem 700 bolt face is now completely square to the action.</p>

<p>Here is Ernie Bishop&#8217;s pride and joy, a specialty pistol nicknamed &#8220;Batman&#8221; because the black carbon-fiber stock looks like the Batmobile. This is one sophisticated handgun. Complete with scope, the Batman pistol weighs under 7.5 pounds, thanks to the ultra-light stock. The carbon stock is 6 inches wide at the fore-end, yet weighs just one pound. Ernie tells us: &#8220;This gun shoots amazing and is easy to shoot especially with my SEB MAX Rest.&#8221; After these photos were taken, Ernie added a &#8220;field-usable rear-grip stock so [he could]  shoot it prone from a bipod as well.&#8221;</p>
<p>The Batman pistol is chambered for the 6mm &#8220;Long Dasher&#8221;, a 6mm 40&deg;-shouldered variant of the 6.5&#215;47 Lapua. Ernie loads Berger 105gr Hybrid bullets pushed by Hodgdon H4350 powder.</p>
<p><b>Gun Specifications</b><br />
<img class="alignright" hspace='10' src="https://accurateshooter.net/GOTW/6x47casesx350.jpg" alt="6.5x47 Lapua Dasher 40 degree improved">The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15&#8243;-long, Brux 1:8&#8243;-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.</p>
<p><b>Long Dasher Wildcat</b><br />
Shown at right is a &#8220;Long Dasher&#8221; 40&deg; wildcat created by Forum member Sunbuilder. This is very similar to Ernie Bishop&#8217;s chambering, though there may be small variations related to reamer design (such as freebore). Sunbuilder’s 6-6.5×47 Improved (aka &#8220;Long Dasher&#8221;) reamer was made by Dave Kiff of <a href="https://pacifictoolandgauge.com" target="_blank">Pacific, Tool &#038; Gauge</a>. This wildcat cartridge adds about 2.0 grains capacity to the 6.5×47 necked down to 6mm. The case certainly is impressive with that 40° shoulder. We&#8217;re just waiting for the tactical guys to starting run this improved cartridge with its original 6.5mm bore.</p>
<p><em>Here are three <strong>FIVE-shot groups at 500 yards</strong>, shot by Ernie&#8217;s Batman pistol. The first 5-shot group is marked with pink dots, the second with green dots, and the third is measured with the calipers:</em></p>
