Many visitors to the site ask us, “I’ve got a .223 and .308. What will a 6mmBR Norma (6BR) give me that I’m not getting already?” Well first you may well average somewhat smaller groups than your current .223 or .308 rifle (assuming the 6BR has a quality barrel and trigger). A good .308 Winchester can be superbly accurate, no question about that, but the lesser recoil of the 6BR works in the shooter’s favor over a long string of fire. Even with a Rem 700 or Savage action factory action, a 6BR with a benchrest stock, premium barrel, and a high-quality chambering job should deliver 5-shot groups in the high twos to mid-threes, provided you do your job. We have one 6BR rifle that shoots Lapua factory-loaded 6BR ammunition in the low twos and high ones. That’s exceptional, we admit, but it still shows how the 6BR is an inherently accurate cartridge, even with factory loads.
Compared to a .223, the 6BR offers a better selection of high-BC projectiles and small-maker match projectiles (such as Bart Sauter’s “Hammer” and the Vapor Trail line). The 6BR will also deliver considerably more power on the target. Compared to the .308 shooting 168gr MatchKings, a 6BR shooting 105-107gr bullets offers better ballistics all the way out to 1000 yards. (The story changes with .308s with very long barrels pushing the 180-210 grain projectiles). Plus, for most people, the 6BR is just easier to shoot than a .308. Recoil is less than half of the .308 Win cartridge. Both the .308 and 6BR chamberings offer good barrel life, but the 6BR uses 15-18 grains less powder, saving you money. Here’s how the 6BR stacks up vs. a number of popular calibers:
Story based on Report by Bryan Blake, Blake Machine Company
Here’s the gold medal-winning .308 Win rifle of the 2020 F-TR National Mid-Range Champion, Andy Cyr. Arizona native Cyr won the F-TR Mid-Range Championship with an impressive score of 1761-72X out of a possible 1800 points. At this three-day Mid-Range event at Ben Avery in Phoenix, all 180 rounds were shot at 600 yards. Andrew delivered a convincing victory, winning by NINE points over runner-up James Crofts, a past national champion himself. We congratulate Andrew on his impressive win. And today’s Sunday GunDay feature examines the details of Andrew’s impressive .308 Win F-TR rifle.
Cyr Overcame Incredibly Tough Conditions at Ben Avery
After Day One of the Mid-Range Nationals, Andy was in 5th place. Andy made up some serious ground on the next two days despite winds that were well into the 20 MPH+ range. In fact, many experienced shooters took misses (not hitting the scoring ring) because the winds were so fierce. Interestingly, Andy’s 1761-72X score beat all but eight F-Open shooters.

F-TR Mid-Range Championship-Winning .308 Win Rifle Specifications:
Blake Barrel and Rifle 32″ .30 Caliber, 1:11″-twist barrel with custom specs
McMillan XIT Stock (lightened with ports on butt area)
Borden BRM Action
Kahles K1050 10-50x56mm Scope
Phoenix Bipod with F-Class Products lowering kit and skeleton legs
Andrew Cyr’s Championship-winning F-TR rifle was built by Phoenix-based Blake Barrel and Rifle (BBR) in 2018. Interestingly, this rifle was originally built for Andy’s daughter Jessica. The rifle was used by Andy a few months later. The rifle features a severely-lightened XIT stock with the grip smoothed out. Andy was actually the first customer of Blake Barrel and Rifle back in 2018. He has always been willing to try out new rifling profiles, twist rates, and barrel configurations as recommended by BBR.
Bryan Blake tells us: “Many customers demand exact specs and there is no way of changing their mind, even if it is factual-based. With Andy he was always willing to try new things, some things didn’t work well, but some things worked very well, just like the barrel used to win the Nationals.” Andy preferred a heavier barrel in the chamber area than most TR shooters. The shank diameter is 1.350″ rather than 1.250″. What this does is keep as much material around the chamber, which is the hottest area of the barrel. That way the barrel is less affected by heat over a string of fire, since the heat can be dissipated into a larger area.
Andy used a 32″ barrel, a length not commonly used in F-TR anymore. Most are running 30″ or even 28″ now. Many folks think a shorter barrel is more accurate so these competitors do not use a 32″ barrel. Well as you can see by his results, Andrew’s 32″ tube shot great. The extra length was NOT a handicap. We should remember that longer barrels can normally produce higher velocities than shorter barrels or deliver equivalent speeds with less pressure.
Many people also believe that a 1:9-10″ twist is needed to shoot 200-grain class bullets out of a .308 Win accurately. However, Andy took the advice of Blake Barrel and Rifle, and went with a 1:11″-twist Blake cut-rifled barrel. Many would say this twist is too slow, and some online calculators say a 1:11″-twist won’t fully stabilize 200-grain bullets. Obviously this is also not the case. Andy’s 11-twist and Berger 200-grain Hybrid bullets (NOT 200.20X bullets) work very well with this combination. NOTE: Andy uses an F-Class Products barrel tuner to tune his load. He will sometimes even alter tune between relays to compensate for changing barometric conditions.
Winning .308 Win Load — Lapua Palma Brass, VV N550, CCI 450s, Berger 200gr Hybrids
Andy Cyr took the Mid-Range title loading Vihtavuori N150 powder, CCI 450 primers, Berger 200gr Hybrids, and Lapua .308 Win Palma brass. Andy does not push his bullets very fast and finds a big accuracy node at the mid-2600 FPS range. He jumps his bullets .015″ off the lands. One thing Andy consistently does is test, test, test. He will test different powders, charge weights, seating depths nearly every time he is at the range. He will shoot a different load for each string to see what works best.
Profile of 2020 F-TR Mid-Range National Champion — Andrew Cyr
Father and Daughter Compete Together
Andy started shooting F-Class in 2012 to help him shoot better in the PRS series. He hoped to learn to read the wind better and get more experience in long-range shooting in general. After shooting F-Class he was hooked and found he enjoyed it more than PRS. Andy and his daughter Jessica have shot many state matches together, with both of them shooting F-TR. Jessica owned the Mid-Range 20-shot woman’s Aggregate record for years with a score of 200-11X. Interestingly Andy shot his very first clean at 1000 yards at the Nationals in Raton, NM in 2018 with a score of 200-11X also. This year Andy started using a spotting scope to help read mirage and it has helped him tremendously he reports.
The “Master” Beat the “High Masters”
Andy is currently classified in Mid-Range as a Master for F-Class, not yet High Master. Even after winning the F-Class Mid-Range Nationals, the most prestigious F-Class match of the year, he is still classified as a Master. Andy’s 1761-72X score works out to 97.8% of a perfect 1800. But the requirement for F-Class High Master is 98%. That just shows you how tough the conditions were at Ben Avery this year. But still the Master beat ALL the High Masters — if you look at the score sheet above, all the other Top 10 F-TR competitors were High Masters. Impressive. And we believe Andy is the first Arizona resident to ever win a national F-Class Championship in either F-Open or F-TR.
About Blake Barrel and Rifle Blake Barrel and Rifle (BBR) has been in business since 2018. BBR built the rifle that Brian Bowling used to win the 2019 F-Open National Championship. And now another ultra-accurate BBR-built rifle has won the 2020 F-TR Mid-Range Championship. Bryan Blake tells us that Blake Barrel and Rifle has recently upgraded BBR’s rifle barrel building equipment. There are advanced CNC lapping machines, CNC bore-honing machines, and all-new, proprietary rifling cutter designs that no one else in the barrel business uses.
Blake Barrel and Rifle produces cut-rifled, 6-groove barrels with a unique rifling profile no other barrel manufacturer is using. Blake barrels have an impressive winning record in recent major competitions — earning National Championships, plus many match wins and podium performances. Bryan Blake tells us that “The time and quality control spend on Blake barrels is second to none and the proof in the results.” For more information, visit Blakebarrel.com.
You can spend thousands on a rifle, but that expensive hardware won’t perform at its best if you have poor trigger technique. One key element of precision shooting is trigger control. Our friend Kirsten Joy Weiss has produced a good video that shows how to refine your trigger technique for better accuracy. In this video, Kirsten talks about the actual placement of a shooter’s index finger on the trigger. It is important to have the finger positioned optimally. Otherwise you can pull the shot slightly left or slightly right.
Kirsten tells us: “Finger placement on the trigger might not seem like a big deal, but it actually is. The reason for this is because, depending on where your index finger is placed on the trigger, [this] translates to different muscle interactions with the gun.” Watch this video to see Kirsten demonstrate proper finger placement (and explain problems caused by improper finger positioning).
When you pull the trigger, you only want to engage the last section of your finger, in order to avoid unwanted muscle engagement and to achieve a smooth shot. Remember there is a “sweet spot” between the crease (first joint) and the tip of the finger. If you position the trigger in that “sweet spot”, you should see an increase in your accuracy. Don’t make the mistake of putting the trigger in the crease of your finger, as shown below.
Effects of Incorrect Finger Placements
You want to place the trigger shoe between the end of your finger and the first joint. If you place the trigger on the very tip of you finger you’ll tend to push the rear of the rifle to the left when engaging the trigger, causing shots to go right (for a right-handed shooter). On the other hand, if you put the trigger in the crease (first joint), you’ll tend to bring the rear of the rifle to the right, causing shots to fall left. This is illustrated below for a right-handed shooter.

Are you tired of struggling to fill your rear sandbags and other sand-filled shooting supports? With a conventional plastic funnel it can be difficult to get the bags filled to full capacity. It’s also time-consuming and awkward to keep pouring sand into a small funnel top.
21st Century Shooting has a solution — a tool that makes it WAY easier to fill all types of sandbags and sand-filled shooting rests, including PRS bags, Bulls Bags, and X-Bags. The 21st Century Sand Bag Filler has a large transparent bottle that holds a lot of sand. This attaches to a nicely-machined threaded grip section that feeds the sand into a small-diameter insert tube. This smaller tube easily fits in the small fill-ports of sandbags. The small tube also allows you to steer the sand flow to the corners of your bags to get a more even, uniform fill.
This video from F-Class John shows how to use the 21st Century Sand Bag Filler. John explains how to fill the sand bottle, than shows how to efficiently fill an Edgewood Dead-bottom bag with sand. John was impressed. At the 2:26 mark John notes: “This is pretty ‘kick ass’ … It is just sucking up the sand into this bag… that is fast”. John is sold on this tool: “I’ve got some giant SEB and Protektor bags. Before I had this tool, I’ve used any number of methods in the past and it’s probably taken me a good hour to pack a bag properly.” Now John says he can fill a big bag in a fraction of the time.
Along with benchrest rear bags, such as the new SEB Premium Bigfoot shown above, there are many other sand-filled support bags. Shown below are some popular bags. The Uncle Bud Bulls Bag has long been a favorite of varmint shooters. It’s very stable but does require a LOT of sand. The 21st Century tool will dramatically shorten filling time for a big Bulls Bag or X-Bag.
You’ve probably heard the term “Terminal Ballistics”. But do you really know what this refers to? Fundamentally, “Terminal Ballistics” describes the behavior of a projectile as it strikes, enters, and penetrates a target. Terminal Ballistics, then, can be said to describe projectile behavior in a target including the transfer of kinetic energy. Contrast this with “External Ballistics” which, generally speaking, describes and predicts how projectiles travel in flight. One way to look at this is that External Ballistics covers bullet behavior before impact, while terminal ballistics covers bullet behavior after impact.
The study of Terminal Ballistics is important for hunters, because it can predict how pellets, bullets, and slugs can perform on game. This NRA Firearm Science video illustrates Terminal Ballistics basics, defining key terms such as Impact Crater, Temporary Cavity, and Primary Cavity.
External Ballistics, also called “exterior ballistics”, is the part of ballistics that deals with the behavior of a non-powered projectile in flight.
Terminal Ballistics, a sub-field of ballistics, is the study of the behavior and effects of a projectile when it hits its target.
If the battery on your safe’s electronic lock is more than a year old, or if it is not giving you the right voltage, replace it today!
Well it’s November folks — winter is around the corner. This time of year, many of our readers are putting their guns away in a safe for the winter. It’s easy to just tuck the guns away and forget about them. But there’s something you should do before you shut the safe door. If you have a safe with an electronic keypad, you should replace the battery every year as a precautionary measure. Trust us, you don’t want to come back in a few months and find that the keypad memory is kaput, and you’re locked out. That can lead to frustration and an expensive locksmith visit.
Here’s a true story. I have one safe with a Sargent & Greenleaf (S&G) keypad. A couple years back, in early December, I went to get into the safe. I punched in the correct combination, but all I got was a rapid “beep, beep, beep, beep” after I finished the last combination entry. I tried again to ensure I entered the combination correctly (I did). But again, the locking system responded with multiple rapid beeps indicating something was wrong. And the safe would not open. Now I was worried….
I popped out the battery holder (which slides in from the bottom of the keypad housing on the door). I removed the battery and tested it with a volt-meter. The 12-month-old Duracell 9-volt battery only registered 6.1 volts.
Low voltage was the problem. I went down to the store and got a couple new 9V batteries. I tested the new batteries and both measured 9.4 volts output. I slipped one of the new 9V batteries into the keypad housing, punched in the combination and everything worked OK again. Eureka.
Most electronic locks for safes WILL “remember” the combination for a period of time even when the battery is low (and the keypad’s “brain” should retain the combination when you remove the battery for replacement). However, a dead battery, or extended periods of low voltage can give you problems. Don’t rely on wishful thinking…
Kestrel wind and weather meters are often regarded as the best on the market — for good reason. Here are a series of three videos by F-Class John that show how the Kestrel 5700 with Elite Ballistics works with Applied Ballistics APP software and Link connection.
This Part I Video starts with a basic Kestrel Anemometer (blue case, 00:00-00:40) wind meter. Then reviewer F-Class John looks at the “smart” Kestrel 5700 with Elite Ballistics. John explains the many features of the Kestrel 5700 and how it holds a powerful ballistics calculator in the convenient, easy-to-tote Kestrel package. With Elite Ballistics, once you enter data about your bullets, velocity, zero, and rifle, the Kestrel can calculate come-ups and wind corrections. If you don’t yet own a Kestrel, we highly recommend you watch this series of videos that explains advanced Kestrel features in detail.
This Part II Video shows the key features of the advanced software APP used by the Kestrel 5700 unit with Elite Ballistics. The Kestrel 5700 can “talk” to a mobile device that runs the Applied Ballistics software APP that contains bullet databases and allows you to enter key information such as muzzle velocity, bullet BC, zero distance, velocity, wind, and environmental factors (altitude, temperature etc.). There are also gun-specific factors such as scope height over bore and barrel twist rate. The video also explains how “range cards” are created and how to view them with your Elite Ballistics-enabled Kestrel. John notes: “The APP is great because you don’t have to fiddle with the Kestrel’s buttons. It’s much easier to enter data and change settings with the APP.”
This Part III video shows how to determine true wind direction by aligning the SIDE of the unit into the wind. You essentially want to set the unit 90 degrees to the wind direction so the impeller runs as slowly as possible. Then, after you set your target distance (See 3:03), the unit can give you precise come-ups for your intended target (10.28 MOA for 559 yards here). The Kestrel then calculates the cross-wind correction as well (See 3:12).

Craters may look interesting on the moon, but you don’t want to see them on your primers. Certain mechanical issues that cause primer craters can also cause primer piercing — a serious safety problem that needs to be addressed. If you have a gun that is cratering primers (even at moderate pressure levels), there is a solution that works with many rifles — send your bolt to Greg Tannel to have the firing pin hole bushed.
Shooters who convert factory actions to run 6BRs, 6PPCs or other high-pressure cartridges should consider having the firing pin bushed. These modern cartridges like to run at high pressures. When running stout loads, you can get cratering caused by primer flow around the firing pin hole in the bolt face. The reason is a little complicated, but basically the larger the hole, the less hydraulic pressure is required to crater the primer.
A limited amount of cratering is normally not a big issue, but you can reduce the problem significantly by having a smith fit a bushing in the firing pin hole. In addition to reduced cratering, bushing the firing pin often produces more consistent ignition.
This is a highly recommended procedure that our editors have had done to their own rifles. Greg Tannel (Gre-Tan Rifles) is an expert at this procedure, and he does excellent work on a wide variety of bolts. Current price for a bushing job, which includes turning the firing pin to .062″, is $92.00, or $100.00 with USPS Priority Mail return shipping.
If you have a factory rifle, a bushed firing pin is the way to go if you are shooting the high-pressure cartridges such as 6PPC, 6BR, 6-6.5×47 and 6.5×47. This is one of the most cost-effective and beneficial upgrades you can do to your factory rifle.
