Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who did an interesting comparison test with two .243 Winchester barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.
Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.
Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.
LESSON LEARNED — Heat Kills Barrel Life
Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!
Monitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:
“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.
I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”

Available for under $230.00 including front bag, the Caldwell Fire Control front rest is a very good value. It makes the co-axial, joystick design more affordable than ever. We used the Fire Control front rest when testing our Ultimate Varminter 20 Practical AR. Once we removed some sand from the tri-lobe front bag, the rest worked quite well.
Get a Fire Control Rest for $220.99
Right now you can get the Caldwell Fire Control Front Rest for just $220.99, an 18% savings off the regular price. The $220.99 Amazon price is a great deal for guys on a tight budget who want a modern joystick-style front rest (this same Caldwell rest sells for up to $269.99 elsewhere).
With the conversion described in this article, you can put together a system that works pretty darn well, and is more than adequate for many applications, including prairie-dog hunting (from a bench). Put the money saved into a nice custom, hand-lapped barrel or some bullets for your varminter.
Upgrading Fire Control Front Rest with Sinclair Top
While most Fire Control owners are happy with the product, many have wanted to replace the tri-lobe front bag with a more conventional front bag from Protektor or Edgewood. This isn’t as easy as it looks because the width of the Fire Control top is too narrow for most standard 3″-wide front bags. On a “special order” basis, Protektor has crafted some narrower leather front bags that fit pretty well, but some shooters have decided to “upgrade” the entire front assembly.
Forum member Doug M. (aka DrJeckyl), has come up with an elegant solution that allows a Sinclair Int’l Benchrest Rest Top to be fitted to the Fire Control Rest. Doug notes: “The Caldwell Fire Control is a nice rest for the money, but it comes up short in the rest top department. The Sinclair RT-3 [or its replacement, the Gen II B/R top] fits perfect with minor modifications.” Shown below are the main components:
To adapt the Sinclair RT-3 or Gen II B/R top, Doug merely had to drill a couple holes in the RT-3 baseplate, and adapt a spacer to get the height correct: “The Caldwell factory top has a raised mounting portion so a 1/8″ piece of stock will be needed as a spacer to the flat-bottom RT-3. The spacer needs to be cut to the same length as the movable portion on the rest. And you should plan the mounting accordingly so the left thumbscrew clears the vertical height column at full left position (there is a cutaway in the rest under the thumbscrew that allows for easy access to the screw).” We labeled the photo with dimensions, but Doug cautions you should measure your own original plate to insure the drill locations are correct for your unit.
The completed installation, with the RT-3 installed on the Fire Control rest, is shown at the top of this article. Doug says it works very well. To learn more about this conversion, with Doug’s measurements for the hole-spacing and his specs on the fasteners, go to the original thread in our Shooter’s Forum. NOTE: Sinclair no longer sells the RT-3 top, but Sinclair’s $89.99 Gen II B/R top can be converted just as easily. LINK to Fire Control Rest Top Conversion Forum Thread.

Every Saturday we present interesting, informative videos for our Daily Bulletin readers. Here we feature five YouTube videos that offer a ton of useful information for serious shooters. We start with a great video about setting up rifle, rest, and bag on the bench. Then Hall-of-Fame benchrest shooter Speedy Gonzalez shows smart methods for cleaning barrels. Next F-Class Ace Keith Glasscock explains how to optimize your rifle after travel. In the fourth video, AutoTrickler inventor Adam MacDonald shows how to optimize the AutoTrickler V4. Next the truly outstanding 21st Century Power Neck-Turning lathe is showcased.
How to Set Up Your Rifle, Rest, and Bag on the Bench
To get the best results in benchrest shooting, you need to set up all the gear on your bench properly. That includes front rest placement, rear bag position, spotting scope set-up, and placement of cartridge holder/caddy, and possibly an elbow/forearm rest. When setting up the hardware, you need to align the front rest and rear bag properly to get optimal tracking. In addition you want to make sure the rear bag doesn’t slide or rotate a bit from shot to shot. And you also want to set your seat height/location so the shooter’s position is optimal and comfortable. This helpful video shows how to set up your rifle and gear for a benchrest match or load development/practice at the range. Credit to Boyd Allen for finding video.
Cleaning Barrels with Speedy — Smart Techniques
There are many effective methods to clean barrels. But some are more efficient that others and can help you do the job more quickly, with less effort. Here respected gunsmith and Hall-of-Fame benchrest shooter Speedy Gonzalez shows his procedures for cleaning competition barrels. He uses Sharpshoot-R Liquid Patch-Out and Wipe-Out Accelerator as primary solvents. Watch carefully — Speedy has some clever techniques for starting a patch in the rifling, and he is also careful about exiting the muzzle when brushing. Speedy also explains the importance of keeping your rods clean. And he prefers nylon brushes because, as the barrel starts to get wear in the throat, “the bronze bristles will actually start eating into that and you’ll see little grooves if you have a good borescope.” (See video 00:38-01:35)
Getting Rifle Ready After Traveling — Keith Glasscock
Keith Glasscock is one of America’s top F-Class shooters, having finished Second at the National Championships multiple times. Keith, who has an engineering background, runs the popular Winning in the Wind YouTube channel. There you’ll find great advice on wind reading, load tuning, precision reloading and many other topics. In this video, Keith offers very smart advice on how to re-assemble your rifle after you have traveled to a match or practice destination. Keith explains how to check the fasteners on the gun and set up the scope properly if you removed it while traveling.
Adjusting AutoTrickler V4 with its Inventor, Adam MacDonald
Adam MacDonald is the brilliant Canadian engineer who created the AutoTrickler series of automated powder dispensing systems. These work with advanced scales to dispense powder rapidly, but with a precise final trickle accurate to a single kernel. In this video, Adam explains how best to adjust and calibrate the AutoTrickler V4 when using powders that flow at different rates.
21st Century Power Neck-Turning Lathe — Great Tool
Turning case-necks can be tedious and tough on older hands if you’re using hand-held tools. Quite a few years ago 21st Century released a great compact, neck-turning lathe that delivers superb, consistent results. This Editor uses that original lathe with hand crank and I can affirm that it works great. It is easy to use, fast, and the turned necks come out smooth with consistent rim thickness. But you still had to turn a crank. Well, in 2018, 21st Century created an upgraded Power Neck-Turning Lathe with an electric motor and lever to advance the cases to the cutter. The power head glides on stainless steel guide rails. Power is controlled with a red button in the feed handle.
This advanced, powered mini-lathe is absolutely superb. It works brilliantly and makes the task of turning case-necks fast and VERY easy. And there is even a 3-Way trimmer upgrade that will trim cases to length at the same time as the necks are turned.
BONUS — How to Spot Fake Online Sellers of Components
With the shortage of premium reloading components, particularly powder and primers, many handloaders are desperate to find components when even big companies such as Midsouth and MidwayUSA are completely sold out. Enter the scammers. There are criminals, many based overseas, who have created entire websites designed to steal your money. You might find such a site when searching for “Varget powder in stock” or “CCI BR4 primers”. These sites look like regular business webstores, with product photos and modern shopping cart systems. But it’s all a scam.
Key giveaways are: 1) The site does NOT take Visa, Mastercard, or Discover but requires payment with Zelle, Venmo, Bitcoin, or AppleCash only; and 2) The site has hard-to-find powders, such as Varget and H4350, that nobody else has, and you can put thousands of pounds in the shopping cart.
Bottom line here — if the site allows you to order vast amounts of powder and/or primers, and does not take ANY major Credit Card types, it is almost surely a scam. If you see links to pay with Crypto-Currency (such as Bitcoin) run away!

Bryan Litz, founder of Applied Ballistics LLC, has a new Facebook page where, multiple times every week, he posts useful ballistics info and shooting tips. We recommend that Facebook users check out the new Bryan Litz Ballistics Facebook page. Here is one interesting example from that page. Bryan analyzes the Crosswind Weighting Factor (CWF). The Crosswind Weighting Factor (CWF) shows where a bullet’s trajectory is most susceptible to wind. By understanding CWF, shooters can better predict how wind affects bullet flight, especially at extreme ranges, when the projectile has gone transonic.
Crosswind Weighting Factor (CWF) graphs show where bullet trajectories are most susceptible to wind.
Where does the wind have the most effect?
At the shooter?
At the target?
Halfway?
Bryan Litz explains: “Out through the supersonic range, the CWF is maximum at the shooter. However as the trajectory extends into transonic, the max CWF gets pushed down range. That’s because the greatest segments of lag time in the bullets trajectory are at transonic where the drag coefficient is maximized around Mach 1.” [Editor: So if your bullet stays fully supersonic during its flight to your target, you can normally expect the CWF to be highest at your shooting station. But once the projectile drops into transonic speeds then the situation changes.]

GunsAmerica Digest has a new Suppressor Academy webpage that provides host of helpful information about suppressors (aka “silencers” and “cans”). The Suppressor Academy online resource page features in-depth articles with important information for anyone considering acquiring a suppressor. The articles explain the key benefits of suppressors, how to choose a suppressor, and how to comply with Federal and state laws regulating suppressors. Below we link to four Suppressor Academy articles. Click the title for each topic to read the full-length article.
Suppressors are now legal in 42 U.S. States. There are certain legal requirements for obtaining a suppressor, including paying a $200 Tax Stamp. To own a suppressor you must be legally eligible to purchase a firearm, pass a BATFE background check, pay a one time $200 Transfer Tax, and satisfy age requirements. (SEE ALL Requirements). In most (but not all) of those states you can use a suppressor for hunting. The eight (mostly blue) states which still prohibit civilian suppressor ownership are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. READ FULL ARTICLE on GunsAmerica Digest.
Suppressors serve one main purposes — to reduce the sound levels produced when firing pistol or rifle rounds. But GunsAmerica Digest editor True Pearce notes there are many other reasons to own a suppressor. A suppressor can reduce muzzle blast and felt recoil. The suppressor may prevent hearing damage that occurs through bone conduction better than earplugs and muffs because it reduces the noise energy at the source. When hunting, the reduced shot noise can help avoid spooking game. Having a suppressor also makes it easier to communicate when working as a team on a hunt. And, when compared to a muzzle BRAKE, suppressors are much less likely to kick up dust, dirt, sand, and snow when you shoot prone. READ FULL ARTICLE on GunsAmerica Digest.
There is some confusion surrounding the laws concerning suppressors, which are now legal in 42 U.S. States. In most jurisdictions that allow suppressor ownership, no additional state permit or license is required. But you do have to comply with Federal requirements when acquiring the suppressor. You may wish to create a trust to own the suppressor — there are some important practical advantages to having a suppressor trust. The Traditional NFA Gun Trust allows multiple responsible parties, i.e. “trustees”, to legally have possession of the suppressor. Each trustee must be verified and for each suppressor owned by the trust there will be a $200 Tax Stamp. READ FULL ARTICLE on GunsAmerica Digest.
When shopping for a suppressor there are many factors to consider: price, build quality, materials, sound level reduction effectiveness, weight, ease of mounting, and ease of cleaning and maintenance. We recommend that all suppressor buyers research the options. Check the manufacturer’s reputation, check diagrams for disassembly and maintenance. There are always trade-offs. Shorter suppressors may save some weight, but if they don’t cut the decibels as well you may be disappointed. You also need to consider the caliber — will your suppressor be used on multiple firearms? If so then get one that fits the largest caliber you will shoot. READ FULL ARTICLE on GunsAmerica Digest.

SIG Sauer has been awarded the Next Generation Squad Weapons System (NGSW) contract by the U.S. Army after a 27-month testing/evaluation process. This contract is for a new basic rifle and a new lightweight machine gun. Both new NGSW arms will use a new high-velocity 6.8mm cartridge — the 6.8×51 FURY. This 6.8×51 FURY Hybrid Ammunition features a patented bi-metal hybrid case designed to handle pressures higher than conventional ammo, resulting in significantly increased velocity and on-target energy in lighter weapons. These new rifles will also feature SIG Sauer suppressors.
The SIG-LMG (XM250) lightweight belt-fed machine gun and SIG MCX-SPEAR Rifle (XM5) are purpose-built to use SIG FURY 6.8 Common Cartridge Ammunition enabling greater range and increased lethality while reducing the weapon/ammo weight carried by soldiers. Both the SIG-LMG (XM250) and MCX-SPEAR (XM5) deliver significant advancements compared to the current M249 and M4/M4A1.
SIG Sauer’s new 6.8×51 XM250 and XM5 combat weapons both have a suppressor as standard issue equipment. SIG SLX Suppressors are designed to reduce sound signature and flash, and they feature a patented quick-detach design for easy installation/removal.
“The U.S. Army is taking a bold step toward the command of the 21st-century battlefield and SIG SAUER is immensely proud to be the selected provider for this historic revolution in infantry weapons. The fielding of the SIG SAUER Next Generation Squad Weapons System will forever change the dynamic of military engagement for America’s warfighters with American innovation and manufacturing,” stated Ron Cohen, President, and CEO of SIG Sauer, Inc.
SIG Sauer states: “The SIG FURY Hybrid Ammunition, SIG-LMG (XM250), SIG MCX-SPEAR Rifle (XM5), and SIG SLX Suppressors meaningfully advance soldier weapons technology to meet the emerging requirements of the U.S. Army.”
But is there a downside to switching to a completely new cartridge type? Yes — the problem is building ammo supplies. BreakingDefense.com notes: “While both the legacy rounds [5.56×45 and 7.62×51] have significant stockpiles built up over the years, getting ammunition levels to where they need to be is a daunting challenge”. At a Pentagon media briefing, Brig. Gen. William Boruff, executive officer for armaments and ammunition explained: “Current ammunition is such that the availability is almost an afterthought. This is because the Army has spent decades refining its process to ensure a sufficient inventory of 5.56 ammunition is available and the industry base is present to continue replenishing on a consistent basis. The Army has not introduced a new caliber for about 65 years[.] Doing so will require extensive coordination” to ramp up production and build 6.8×51 inventories.
The SIG Sauer XM5 rifle offers advantages over current U.S. military rifles. The new SIG rifle is built on the MCX platform with the added firepower of the 6.8×51 round. The XM5 features familiar AR-style ambidextrous ergonomics for easy transition from the legacy weapons to the SIG NGSW system. The weapons will also employ SIG Sauer “Next Generation” Suppressors.
SIG Sauer is proud to offer the advancements of the NGSW System in the SIG 277 FURY Hybrid Ammunition (the commercial variant of the SIG 6.8×51 FURY Ammunition round), SIG MCX-SPEAR Rifle, and the SIG SLX Suppressors available to the consumer.

In January 2022, the CMP noted that the ISSF was changing its 3×40 three-position event to a 3×20 course of fire and that three-position and air gun finals were also being changed. There has been uncertainty as to what the final version of these rules will be. Since CMP competitors need to know what the CMP rules are going to be this year, the CMP has decided to finalize its 2022 CMP Smallbore Rifle Competition Rules based on what is now known, namely that the 60-shot 3×20 course of fire is likely to stay, while ISSF rules for finals have just seen yet another change.
The updated CMP Smallbore Rifle Rules adopt the 60-shot 3×20 course of fire as the standard three-position event but leave previous finals rules in place until there is more clarity regarding whether the new 2024 Olympic finals rules can or should be adopted for CMP smallbore competitions.
The major change in this Smallbore Rules update is the recognition of the 3×20 course of fire as the standard 3-position event. All smallbore position EIC matches where competitors can earn credit points for the new Distinguished Smallbore Position Badge must be 3×20, not 3×40, events.
Smallbore position tie-breaking has also changed. Three-position ties will be broken according to the highest standing score, then the highest kneeling score. Inner tens will not be used unless two competitors are tied in all three positions. Smallbore prone competitors are NOTE affected by these latest rule changes except that new rules for conducting 40-shot prone events on electronic targets have been added.
Given the uncertainty regarding ISSF finals rules, this edition of the CMP Smallbore Rifle Rules will still include the 45-shot progressive elimination final that the ISSF previously used (Rule SB10.4) and a 24-shot prone final that was previously used by the ISSF.

Jessie Harrison — one of the greatest female pistol shooters on the planet. In the video below, Jessie offers good tips on safe handgun mag changes.
In this Pro Tip Video, Jessie Harrison talks about Dry-Fire Pistol Training:
One of our Forum members asked: “Are there any good books on pistol marksmanship? I’m looking for a book that covers techniques and concepts….” Here are eight recommended titles that can make you a better pistol shooter. These books run the gamut from basic handgun training to CCW to Olympic-level bullseye shooting.
Good Guidebooks for Pistol Shooters
There are actually many good books which can help both novice and experienced pistol shooters improve their skills and accuracy. For new pistol shooters, we recommend the NRA Guide to the Basics of Pistol Shooting. This full-color publication is the designated student “textbook” for the NRA Basic Pistol Shooting Course.
If you’re interested in bullseye shooting, you should get the USAMU’s The Advanced Pistol Marksmanship Manual. This USAMU pistol marksmanship guide has been a trusted resource since the 1960s. Action Shooters should read Practical Shooting: Beyond Fundamentals by Brian Enos, and Practical Pistol by Ben Stoeger. Brian Enos is a well-known pistol competitor with many titles. Ben Stoeger is a two-time U.S. Practical Pistol shooting champion. Julie Golob’s popular SHOOT book covers pistol marksmanship, along with 3-Gun competition. Julie holds multiple national pistol shooting titles.

Applied Ballistics has just launched a great, new online resource for shooters: The Science of Accuracy Academy. This subscription-based website is launching with nearly 30 podcast episodes, with many more planned, as well as video content, Zoom classes, and much more.
The main goal of this new online resource is to adapt and modernize the delivery of content coming from Applied Ballistics LLC. In past years, books, DVDs, and seminars were the primary avenues for delivering information. Modern technology has evolved, and the delivery of information can be done in more efficient ways such as streaming videos, podcast discussions of book and seminar content. In addition to being a more modern delivery platform, The Science of Accuracy Academy allows for more frequent updates than traditional books and DVDs.
Bryan Litz, owner of Applied Ballistics LLC tells us: “I’m very excited about this avenue to share what we’re learning in the Applied Ballistics lab. I think many shooters will benefit from the podcasts, which contain very insightful discussions and can be enjoyed in your car, or as you work. We look forward to publishing more of our research thru the Science of Accuracy Academy”.
About the Science of Accuracy Academy Content and Programs
Below, Bryan Litz comments about the Academy’s new podcast offerings and other interactive content. Bryan notes: “We’ve benefited a great deal from practicing the scientific method, and we want to share what we’ve learned.”
Book Content via Podcasts — Many of the podcast episodes are specific reviews of Applied Ballistics book chapters. I’ll sit with Mitch or Francis (both experienced, champion shooters) and discuss the chapter, what it was like to do the tests. We will also discuss behind the scenes problems, as well as what we’ve learned since publishing the books. This lets subscribers get knowledge from the books. And, as a podcast, you can listen while driving, working out, or whatever.
The World of Doppler Radar — In recent years we have spent considerable time visiting shooting matches with the AB Mobile Lab and running Doppler radar. Between that and some of the government contracting work, we’ve built up a lot of experiences and it’s been a long time since a book was published. This Academy is a great outlet for us to update the shooting world on what we’ve been doing and learning.
Ballistics Science and Precision Loading — We’ve been doing hardcore ballistic science for the past few years and have a lot to share. We’ve come to see some aspects of handloading and shooting in a fundamentally different way. For example, understanding the statistical nature of precision has caused us to re-shape how we make decisions in the handloading process. As a result, we now better understand cause-effect relationships and can make deliberate, reliable progress as a result.
Bryan Litz Announces the New Science of Accuracy Academy
The Lighter Side — Bryan told AccurateShooter.com: “Some of the podcast episodes are much less serious! We have fun arguing about which shooting disciplines are harder. For example, Mitch Fitzpatrick and I talk with Francis Colon and Chad Heckler about PRS vs. ELR shooting. We discuss what we like and dislike about the different sports, what we would like to see changed, and what competition shooting has meant for us as individuals. This open-ended format explores long range shooting from the technical to the personal and everything in-between.”

Q: What’s more important — wind speed, or direction?
A: Obviously they both matter, but they do trade dominance based on direction. For example, a 10 mph wind between 2:30 and 3:30 is only changing its value from 9.7 to 10 to 9.7 mph (bracket of 0.3 mph). However a 10 mph wind between 11:30 and 12:30 is changing its cross wind component value from 2.6 mph left to zero to 2.6 mph right (bracket of 5.2 mph). There is the same 30° change in direction, but this results in a massively different bracket.
Point being, in this case, a direction change is far more critical if it’s near 6 or 12 o’clock. A small direction change when it’s close to 3 or 9 o’clock is negligible.
On the contrary, a change in wind SPEED when it’s near 3 or 9 affects your crosswind component directly. But for a near head or tail wind, a fluctuation in wind speed only causes a small fraction of a change to the crosswind component.
SUMMARY: If you’re in a near full-value wind, pay more attention to wind SPEED. If you’re closer to a head- or tail-wind, nailing the exact DIRECTION will be more important.
