Since this is Mother’s Day, here’s a story about one very special mother — a talented lady shooter who also reared one of the greatest marksmen in history, David Tubb.
We expect you’ve heard of David Tubb, 11-time NRA National High Power Champion. Without question, David is one of the greatest rifle shooters who ever lived. What you may not know is that David came from a family of shooters. David’s father, George Tubb, was a nationally-ranked High Power competitor. What’s more (now this may surprise you), David’s mother “Polly” was was a great shooter in her own right. When she wasn’t rearing a future Champion, Polly was hitting the X-Ring at rifle matches.
Pauline (“Polly”) S. Tubb of Canadian, Texas, earned several rifle championships during the course of her shooting career. In this photo, Polly took a moment to appear for a photo after winning the 1962 National Woman’s Bolt Rifle championship at Camp Perry. One shooter who competed against Polly observed: “I was there as a 1962 Pennsylvania State Team junior! I remember Polly. She beat some of the best Army and Marine shooters and always did it with style and good humor.”
Ever wonder how (and where) Sierra tests its bullets? The answer is underground, in a 300-meter test tunnel located under Sierra’s factory in Sedalia, Missouri. The photo above shows the construction of the tunnel back in May, 1990. Like most bullet manufacturers, Sierra does live-fire bullet testing to ensure that Sierra projectiles perform as promised, with repeatable accuracy. Sierra’s 300-meter test range is the longest, privately-owned underground bullet test facility in the world. Sierra offers free tours of the test tunnel as part of Sierra’s Factory Tour Program.
Sierra Bullets tests every new bullet design and each lot of bullets. Sierra tells us: “When [we] change to a new bullet they are continually shooting them until they get the bullet properly set up and running and the range releases them to run (meaning the bullets shoot to spec). [Testers] are required to shoot at any lot change and periodically throughout the lot … even if it is just a press operator change. Lot sizes can vary from 5,000 to over 100,000 thousand. If anything changes — it is a new lot. When a new operator comes on — it is a new lot.”
Bevy of Barreled Actions for Bullet Testing
Sierra Bullets uses dozens of barreled actions for testing bullets. These barreled actions are clamped in stout, return-to-battery test fixtures. These heavy test fixtures provide near-perfect repeatability (with no human-induced holding or aiming errors). Each barrel has its own logbook to track the barrel’s usage. Interestingly, Sierra does not have a specific round count for barrel life. When a barrel starts “opening up”, i.e. showing a decline in accuracy, then the barrel is replaced, whether it has 800 rounds through it or 5,000.

Sierra Bullets 10-Shot Groups at 200 yards
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? 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″ middle group works out to 0.162 MOA at 200 yards.

This year marks the 10th anniversary of the NRA Springfield M1A Match, scheduled for July 31, 2016 at Camp Perry, Ohio. The Springfield M1A Match will kick off the 2016 NRA National High Power Rifle Championships. With this year’s anniversary M1A competition, more than 4,000 competitors will have shot the classic M1A for score from Camp Perry’s 300-yard line.
Big bucks will be at stake in this year’s M1A match. Springfield Armory is donating over $25,000 worth of cash and prizes, including a $2,000 cash award to the overall winner. All competitors who register by July 15, 2016 will also receive a free Springfield M1A Match T-shirt.
Sponsored by Springfield Armory, the NRA Springfield M1A Match was conceived to promote use of this historic battle rifle, based on the military’s M14. “Springfield Armory has always been about heritage,” stated Springfield Armory CEO Dennis Reese. “I competed myself last year. It was incredibly inspiring to see hundreds and hundreds of our M1A rifles on the Camp Perry firing lines.”
M1A Match Course of Fire
Equipment rules allow pretty much all types/grades of M1As in the match. The one-day course of fire consists of 50 shots at 300 yards on the NRA MR-65F target, as follows: 5 sighters; 20 shots slow-fire prone; 10 shots rapid-fire prone; 10 shots rapid-fire, kneeling or sitting; and 10 shots slow-fire standing.

In recent years, the use of electronic trainer systems has revolutionized training in all disciplines of position shooting. By capturing (and illustrating) key performance variables like the steadiness of a shooter’s hold, accuracy of aiming, and the timeliness of trigger release, these devices can offer tremendous insights into the strengths and weakness of a shooter’s position and technique, making high-level marksmanship training less voodoo and more of a science.
Until now, electronic trainers all suffered from one critical limitation: the inability to be used outdoors in live fire training. Now, however, SCATT has introduced the next-generation MX-02 electronic trainer, a product that can finally support outdoor live firing in broad daylight, as well as dry firing indoors. In addition, the MX-02 is the first electronic trainer to support centerfire rifles. It goes without saying that, when we at AccurateShooter.com were offered an MX-02 test unit to review, we jumped at the opportunity.
How the SCATT MX-02 Works
The SCATT sensor mounted on the end of the barrel has a digital camera that “sees” the black bullseye in the target, even in broad daylight outdoors. Using the bullseye as a reference, the SCATT software tracks the movement of the muzzle relative to the center of the target. The unit can plot these movements as a continuous trace, which appears on a monitor as a squiggly, colored line. Data points from the trace are also available in a tabular spreadsheet format. This allows the shooter to “crunch the numbers”, revealing strengths and weaknesses in his gun-handling and aiming technique.
In our testing, we confirmed that, like SCATT’s earlier indoor-only WS-01, the MX-02 offers excellent support for indoor dry-fire training, which will continue to be the primary means through which position shooters sharpen their fundamental skills. Since the new SCATT uses the same familiar Windows software for data capture and analysis as its predecessors, shooters and coaches upgrading to MX-02 will have no learning curve to overcome, and newcomers to the SCATT platform can tap into the wealth of institutional knowledge accumulated over the years by the shooting community on how to interpret shot data.
It’s in the support for outdoor live firing, however, that SCATT MX-02 distinguishes itself from its predecessors and the competition. Shot trace data captured by MX-02 during live firing turned out to be every bit as valuable (and revealing) as we had hoped. The ability to correlate SCATT tracing with real shots on target gave us a better understanding of the shooting process, and helped the reviewer, already a high-level smallbore prone shooter, uncover a significant problem in his shooting. SCATT MX-02’s outdoor capability is therefore an invaluable feature, particularly for experienced shooters aspiring to world-class performance.
In summary, SCATT MX-02 is an outstanding product that delivers on its promises. We heartily recommend it, both for first-time users of electronic training aids, and also for those shooters who may wish to upgrade their current electronic training system. The MSRP for SCATT MX-02 is $1,799, $500 more than its predecessor, the SCATT WS-01, which is still available. In my view, the $500 premium for the MX-02 is justified by the MX-02’s enhanced capabilities, making it a better long-term investment.
Our complete, 3600-word MX-02 review of the SCATT MX-02 can be accessed through the link below. This full review contains many more photos plus detailed field test results. For the time being, the review only covers our experience with the product in smallbore shooting. An upcoming addendum to the review will include test results from centerfire shooting. Those attending SHOT Show in Las Vegas next week can examine SCATT MX-02 in person. SCATT will have the MX-02 on display at Booth 111.
Hey it’s the end of the work week, so we thought you guys might enjoy a little display of honest-to-goodness American .50-Cal firepower. Today’s video features the General Dynamics GAU-19/B Gatling, shown in a vehicle mount (Part 1) and helicopter side-mount (Part 2). The HumVee-mounted version of this bad boy delivers 1300 rounds per minute of .50 BMG ammo. The effect is awesome to behold. We wouldn’t want to be on the receiving end of a GAU. The original GAU-19/A had a selectable rate of fire — either 1,000 or 2,000 rounds per minute. The GAU-19/B, introduced in 2012, provides the same firepower in a much lighter platform, weighing 106 pounds (not counting ammo storage systems).
Never had a chance to hunt prairie dogs in the American west? Then check out this video. Dan Eigen (aka “Walleye Dan”), host of the We Love It Outdoors Television series, head to South Dakota for some varmint hunting. Dan teams up with Varmint Hunter Association President Jeff Rheborg to patrol some South Dakota Dogtowns where things get serious. In the video, you’ll see p-dog hits at distances from 70 yards to roughly 450 yards. The hunters were shooting from portable, wood-topped swivel rests, using AR-platform rifles on X-type sandbag rest. (Rifle zeroing session is shown at the 5:30+ mark.)
Multiple cameras were employed so you can see both the shooter’s POV and close-ups of the prairie dogs downrange. Watch the shooters having fun with a prairie dog cut-out and some Tannerite at the 9:00-minute mark. This guys are having a grand old time sending critters to Prairie Dog Heaven — we think you’ll enjoy the video.
Prairie Dog Hunting Starts at 2:00 Time-Mark in Video:
NOTE: This video actually covers three sequences: 1) Three-gun training; 2) Prairie Dog Hunting; and 3) Coyote Hunting. We’ve embedded the video so it plays back the Prairie Dog segment from 2:00 to 15:15. If you wish, you can slide the controls forward or back to watch the other segments.

The last half-inch or so of your barrel is absolutely critical. Any damage (or abnormal wear) near the crown will cause a significant drop-off in accuracy. Here are ways you can check the end of your barrel, using a common Q-Tip.
Use Q-Tip for Barrel Inspection To find out if you have a burr or damage to your crown, you can use an ordinary Q-tip cotton swab. Check the edges of the crown by pulling the Q-tip gently out past the edge of the crown. If you have a burr, it will “grab” the cotton and leave strands behind.
Larry Willis has another way to use a Q-Tip: “Here’s a neat trick that will surprise you with how well it works.” Just insert a Q-Tip into your barrel (like the picture below), and it will reflect enough light so that you can get a real good look at the last half inch of rifling and the crown of your barrel. In most cases you’ll find that this works much better than a flashlight. Larry tells us: “I’ve used this method about a jillion times. Q-Tips are handy to keep in your cleaning supplies anyway. This is a good way to judge approximately how well you are cleaning your barrel when you’re at the range. It’s also the best way to examine your barrel when you’re in the field.”

This is a grim tale. A man almost lost the use of his right hand, and did suffer terrible injuries to his fingers. All because he picked the wrong bottle of powder off the shelf.
Similar Labels, Disasterous Consequences
The shooter, Denny K., was assembling some rounds for his brand new 7mm-08 Savage hunting rifle. He thought he was loading with Hodgdon Varget. Instead he had filled his powder measure with Hodgdon TiteGroup, a fast-burning pistol powder. The labels are similar, so the mistake is understandable. But the results were devastating. Here’s what 41 grains of TiteGroup can do in a 7mm-08:
Posting on the Firing Line, in a thread entitled “Lucky to Be Alive”, Denny writes:
“This is the hardest post to post. I know if I had read it a week ago my comment would have been: ‘You have no business reloading’. I had everything perfect, except pouring the wrong powder in the powder measure. I type this slowly with my left hand, embarrassed but … possibly saving someone else a tragedy or, like me, a long drive to the Emergency Room and surgery to save my finger.”
The Still-Sealed Bottle of Varget
Denny did not initially comprehend exactly why the kaboom happened. He thought maybe his new Savage rifle was at fault. Then, on his return home, he discovered something…
Denny wrote: “The seven-hour period it took to go to ER, transport to Trauma Center and surgery made me think it was a Savage rifle issue. Brand new rifle, new brass, triple-checked loading data. The next day I was humbled when I realized the Varget powder was still sealed.
I knew what powder to use. I thought [Varget] was what I used. Not until the following day did I realize the Varget was still sealed.”
At that point, Denny realized what caused the accident — “operator error”. He knew he had to warn others about using the wrong powder: “I knew I needed to share my mistake, even though it is embarrassing, just to remind people. I’ve been reloading for 30 years…”
Editor’s Comment: Denny was not a novice reloader. His experience demonstrates that this kind of mistake can be made by any hand-loader, even one with decades of experience. Be safe guys, take your time when you load your ammo. Remove powders from measures after your loading sessions (pistol powders can look very similar to rifle powders). And by all means CHECK the LABEL on the jug. As the TiteGroup label says: “A little goes a long way.”
It’s not a bad idea to separate your pistol powders from your rifle powders, or perhaps even load for pistol in a separate part of your workshop.
