Can you hit an egg at 600+ yards? We mean hit it reliably — not just by luck. To do that you’ll need good shooting skills and a very accurate rifle. How accurate? Well, a chicken egg is, on average, 2 1/4 inches (57 mm) long and 1 3/4 inches (44.5 mm) in diameter. That means to hit an egg (on demand) at 600 yards, you’ll need a rifle capable of 1/3-MOA accuracy (or better). Forum member DukeDuke has such a gun, and he demonstrated its egg-busting prowess in this short video. DukeDuke’s rifle is chambered in 6BRX (a 30° 6BR Improved) and it’s loaded with DTAC 115gr bullets pushed by Alliant Reloder 17. In the video, the eggs are placed on top of poles set 616 yards from the firing line.
See Egg Hit at 38 second mark…
As you can see in the video, that’s a heck of a nice shooting range where DukeDuke scrambled those eggs at 616 yards. The range is situated just outside of Lake Jackson, Texas. As for the gun… the action is a Rem 700 SA BDL, blueprinted and bedded in a Rem/HS Precision PSS stock. The 31″ barrel is 1:8″-twist Broughton. The “P3″ on the barrel stands for Porter’s Precision Products, Lake Jackson, TX. The rifle was built by Kenneth Porter. The load was 33.5 grains of RL-17 at 2950 fps, with 115gr DTAC bullets touching the lands. Cartridge OAL is 2.400″.
The 6mm BRX was developed by Bob Crone. Retaining the 30° shoulder of the parent 6mmBR case, the BRX has a little less capacity than a 6mm Dasher. Bob told us that his original design for the 6mm BRX always had a .100″ longer head space than a 6mmBR Norma and that he never deviated from that. But after Bob developed the first 6mm BRX, Bill Shehane made a 6mm BRX version that had a .120″ longer head space, and thus some confusion started. In truth, the original 6mm BRX always was (and still is) a chambering with a head space .100″ longer than a 6mm BR Norma.
With today’s Saturday video showcase we feature eight videos from the Popular Backfire YouTube Channel. The host of the BackFire channel, Jim Harmer, also has a good website, Backfire.tv with written reviews. If you’re shopping for a hunting rifle we recommend you read the recent (12/1/2025) Best Hunting Rifles article. Without further ado, here are eight noteworthy videos from the BackFire Channel.
Five Powder Dispenser Comparison Test (All Units Purchased)
If you are in the market for a sub-$500 electronic powder dispenser, definitely watch this review. This Backfire comparison test is notable because the tester spent his own money to purchase all five powder dispensers being reviewed. That means Backfire could tell the full truth, both good and bad, about the machines. In fact, Backfire bought TWO ChargeMaster Lites because one failed (See 14:12 time-mark). The reviewer liked the RCBS ChargeMaster Supreme, but his top choice overall was the Hornady Auto Charge Pro. He favored the overall design, and really liked the way the dispensing speeds could be easily set faster or slower. Here are highlights from the video review:
00:08 Speed Test
03:09 Accuracy Test
07:57 Frankford Arsenal Intellidropper
09:08 Lyman Gen 6
10:44 RCBS Chargemaster Supreme
12:03 Hornady Auto Charge Pro
14:12 RCBS Chargemaster Lite
14:41 Conclusions
Best Rifle Scope Under $500 (2.2 Million Views)
This is a very comprehensive test of ten scopes under $500 MSRP. Unlike many reviews, the tester actually purchased all the tested scopes with his own money to provide a fair, unbiased review. The ten scopes all have approximately 4-14X magnification, common for a hunting/general purpose field scope. The reviewer ranked the $349 Vortex Diamondback Tactical FFP as the Best Overall scope. The reviewer’s first choice for a Target/Competition scope was the $299 Arken 4-16×50 model. The $175 Burris Fullfield E1 Hunting model was named the best “Lightweight, Capped Scope”.
The Backfire team purchased eight rangefinders and tested them in the field. Most of the products are under $500. This is a good review if you are looking for a compact LRF at a moderate price. Looking at performance for the price, for the hunting market, the reviewers favored the Leupold RX-1600 and the waterproof Vortex Ranger 1800. COMMENTARY: If you can afford it, we recommend that serious hunters consider top-end laser rangefinder-equipped binoculars such as the ZEISS Victory RF and Leica Geovid.
Affordable Hunting Rifles under $750.00 (1.3 million views)
Here’s another good Backfire Channel video for hunters looking for a new rig. With hunting season starting soon, this video can save you time and help you get the most bang for your buck. The Backfire team review eight affordable under-$750 rifles: Bergara B-14, Howa 1500 Hogue, Kimber Hunter, Remington 700, Ruger American, Savage 110 Switchback, Tikka T3X Superlite, and Weatherby Vanguard. The Backfire reviewers tested all 8 rifles for function and accuracy (4-shot groups). These 8 rifles were chose for review based on input from Backfire channel viewers.
Accuracy Secrets of a Champion — Interview with Erik Cortina
Our friend Erik Cortina is one of America’s top F-Class marksmen, and he has also achieved notable results in some long-range tactical matches. In this video Erik explains some of the factors that help in load development, wind reading, and achieving long range accuracy. If you shoot F-Class or even just compete in local matches, this video is worth watching. Erik’s Cortina Precision company produces high-quality tuners, tuner brakes, dies and other high quality products.
How to Set Up a Rifle for 1000 Yards
Here’s good video for novice ELR and Long range shooters. The video covers initial zeroing and then working with ballistics at 600-1000 yards. The tester explains the importance of a very stable platform and optics with adequate vertical adjustment and proper parallax control. The featured rifle is a 6.5 Creedmoor Bergara Premier Competition in a dark, gray PMA chassis (this is not the tan rifle in cover shot). Note: Bergara also offers a barreled action that you can put into a different chassis of your choice. The scope is an Athlon Helos BTR Gen2 4-20x50mm. A Garmin Xero C1 radar chrono was used to confirm velocity.
Low-Cost vs. High-Cost Rifles — How They Compare (2 Videos)
Here are two interesting videos that compare the features and performance of rifles at various cost points. The first video compares two rifles with a 10X (1000%) price difference — $350 vs. $3500. Some quite inexpensive rifles can perform very well, if you get lucky with the factory barrel. At the high end of the spectrum you can (hopefully) expect a smoother action, better trigger, more sophisticated stock, and (hopefully) more shot-to-shot consistency. Still a big investment doesn’t always guarantee vastly improved performance. For a deer hunter, a $500 rifle with a modestly-priced scope can probably do the job. If you want to hit prairie dogs at 500 yards and beyond, you’ll need an accurate cartridge and a very good (preferably custom) barrel for consistent hits.
For load development, some guys shoot 3-shot groups. Other guys shoot 5-shot groups, or even 10-shot strings. But for testing its projectiles, Sierra Bullets takes it to another level entirely. A while back Sierra was testing its .30-Caliber 175gr HPBT MatchKing in the Sierra underground tunnel. The results appear above — a FIVE HUNDRED Round group!
500 Shots Form 0.82 MOA Group at 300m (328 yards)
Sierra’s trigger-pullers sent five full boxes of bullets down-range at a single target. The photo above shows the result of 500 shots taken in a 300 meter test tunnel. The raw group size, edge to edge of the farthest shots, is about 3.13 inches, as shown on the calipers’ metal linear scale. Subtract a .308″ nominal bullet diameter* to get the 2.823″ on the digital readout. So you’re seeing a 2.823″ group at 300 meters (328 yards). One MOA at this distance is 3.435″ so this 500-round group is 2.823 divided by 3.435 or 0.82 MOA (0.8218 MOA to be precise).
This 500-round group was shoot as part of a pressure/velocity test for a commercial customer. The cartridge was .308 Winchester, loaded at 2.800″. The powder was Reloder 15. A 26″ barrel was shot from a return to battery rest. The gun was cleaned every 125 rounds and two foulers shot.
What do you think — could you beat this group from a bench for 500 rounds?
One Facebook poster joked: “500-round group? Everyone knows anything less than 1000-round groups are a waste of time and statistically irrelevant.”
Sierra’s 300 Meter Testing Tunnel
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 of its projectiles. Sierra’s 300-meter test range is the longest, manufacturer-owned underground bullet test facility in the world. In years past, Sierra offered free visits to the test tunnel as part of a factory tour.
* Normally, to get an exact group size, you should subtract the TRUE bullet hole size, which is usually smaller than the nominal bullet diameter. E.g. a .308 bullet hole may show on paper as .298 or so. But here, for simplicity, we are subtracting .308″ because we do not have the original target to measure.
We like Lyman’s Electronic Digital Trigger Pull Gauge, which is faster and more precise than the previous model. The latest Lyman Pull Gauge measures trigger pull weights from 1 ounce to 12 pounds with resolution of 0.1 ounces (2.8 grams). It features an adjustable, 4-position rod which retracts into the gauge body. We think that anyone running match triggers below 2.5 pounds pull weight should have a gauge like this. Among the pull gauges on the market, we think the Lyman unit offers great performance for the price.
Features: More Precise Strain Gauge | Improved Grip Shape | Adjustable Rod Lengths
Lyman’s Electronic Digital Trigger Pull Gauge is designed to be the fastest and most accurate trigger pull gauge available. State-of-the-art strain gauge technology allows for repeatable accuracy of 1/10 ounce (2.8 grams). The gauge features a large, easy-to-read LCD display and you can switch from ounces to grams with the push of a button. The gauge can also deliver a pull weight average of the last 10 readings. That’s very helpful when working with factory triggers that may not be very consistent.
The Lyman Trigger Pull Gauge features a solid, collapsible rod with four locking positions. Being able to adjust length makes it easier to use the gauge with a wide variety of firearms — pistols, rifles, and shotguns. The locking feature prevents the rod from flexing when applying pressure to the trigger. When not in use, the rod conveniently collapses into the gauge body, making the whole unit more compact. The new Trigger Pull Gauge comes in an internally-padded plastic case that can be easily stored in a drawer or on your work bench.

The U.S. Army Marksmanship Unit (USAMU) regularly published reloading “how-to” articles on the USAMU Facebook page. One excellent “Handloading Hump Day” post covered preparation of once-fired 5.56x45mm brass. This article, the first in a 3-part series, has many useful tips. If you shoot a rifle chambered in .223 Rem or 5.56x45mm, this article is worth reading. You can obtain once-fired Lake City 5.56x45mm brass for less than half the cost of premium .223 Rem brass.
This week, Handloading Hump-Day will answer a special request from several competitive shooters who asked about procedures for morphing once-fired GI 5.56mm brass into accurate match brass for NRA High Power Rifle use. The USAMU has used virgin Lake City (LC) 5.56 brass to win National Championships and set National Records for many years. In this 3-part series, we’ll share techniques proven to wring match-winning accuracy from combat-grade brass.
GI brass has an excellent attribute, worth noting — it is virtually indestructible. Due to its NATO-spec hardness, the primer pockets last much longer than most commercial brass when using loads at appropriate pressures.
Preparing Once-Fired GI 5.56 Brass for Reloading (Part 1 of 3)
Assuming our readers will be getting brass once-fired as received from surplus dealers, the following steps can help process the low-cost raw material into reliably accurate components.
1. Clean the Brass
First, clean the brass of any dirt/mud/debris, if applicable. Depending on the brass’s condition, washing it in a soap solution followed by a thorough rinsing may help. [This step also extends the life of the tumbling media.] Approaches range from low-tech, using gallon jugs 1/2 full of water/dish soap plus brass and shaking vigorously, to more high-tech, expensive and time-consuming methods.
2. Wet-Tumbling Options (Be Sure to Dry the Brass)
When applying the final cleaning/polish, some use tumblers with liquid cleaning media and stainless steel pins for a brilliant shine inside and out, while others take the traditional vibratory tumbler/ground media approach. Degree of case shine is purely personal preference, but the key issue is simple cleanliness to avoid scratching ones’ dies.
If a liquid cleaner is used, be SURE to dry the cases thoroughly to preclude corrosion inside. One method is to dump the wet brass into an old pillow case, then tilt it left/right so the cases re-orient themselves while shifting from corner to corner. Several repetitions, pausing at each corner until water stops draining, will remove most water. They can then be left to air-dry on a towel, or can be dried in a warm (150° F-200° F max) oven for a few minutes to speed evaporation.
Shown below are Lake City cases after cleaning with Stainless Media (STM). Note: STM Case cleaning was done by a third party, not the USAMU, which does not endorse any particular cleaning method.
NOTE: The USAMU Handloading (HL) Shop does not RE-load fired 5.56 brass. We use virgin LC brass with our chosen primer already staked in place. However, our staff has extensive personal experience reloading GI brass for competition, which will supplement the Shop’s customary steps. In handloading, as in life, there are many ways to accomplish any given task. Our suggestions are note presented as the “only way,” by any means. Time for loading/practicing is always at a premium. Readers who have more efficient, alternative methods that maintain top accuracy are invited to share them here.
3. Inspect Every Case
Once dry, inspect each case for significant deformation (i.e., someone stepped on it), damaged mouths/necks and case head/rim damage. Some rifles’ ejectors actually dig small chunks of brass out of the case head — obviously, not ideal for precision shooting. Similarly, some extractors can bend the case rims so badly that distortion is visible when spinning them in one’s fingers. These can be used for plinking, but our match brass should have straight, undamaged rims.
Dented case mouths are common, and these can easily be rounded using a conical, tapered tool, [such as a .223 expander mandrel. A dummy 7.62 or .30-06 cartridge with a FMJ spitzer can also work.] If most of your brass is of one headstamp, this is a good time to cull out any odd cases.
4. Check the Primers Before Decapping
Your clean, dry and inspected brass is now ready for full-length sizing, decapping and re-priming. Historically, primer crimps on GI brass have caused some head-scratching (and vile language) among handloaders. Our next installment will detail efficient, easy and practical methods to remove primer crimp, plus other useful handloading tips. Until next week, Good Shooting!
Accuracy Potential of Mil-Surp 5.56×45 Brass
So, how accurate can previously-fired GI surplus brass be in a good National Match AR-15? Well, here’s a data point from many years ago that might be of interest. A High Power shooter who wrote for the late Precision Shooting magazine took a Bill Wylde-built AR match rifle to a registered Benchrest match. He had no difficulty obtaining consistent 0.5-0.6 MOA accuracy at 200 yards using LC brass and a generic “practice” load that was not tuned to his rifle.
Stunners in silver. Above are the NRA Leech Cup (left) and Wimbledon Cup (right).
Shooting Sports USA has a fascinating article about the Perpetual Trophies awarded in national-level NRA matches. The story recounts the history behind the elaborate trophies, some from the 1870s. SSUSA’s Jennifer Pearsall writes: “The pieces of wood, stone and precious metal … are more than just instant recognition of achievement. They are the link of the American shooter’s present to his or her patriotic past. As you read this legacy of the NRA ranges, their founders, and the long list of cups, bowls, and plaques, realize that the history of competitive shooting is undeniably a significant part of the foundation of this country”. Read Full Trophy Story HERE.
The NRA was co-founded by Col. William Church and Gen. George Wood Wingate (ranked Captain at the time). Both Church and Wingate hoped to improved the marksmanship skills of American soldiers. One of the newly-formed NRA’s first actions was to issue: “An Act to Establish a Rifle Range and Promote Skill in Marksmanship”. That led to the opening of the famed Creedmoor Range, with a special inaugural match in June of 1873.
Many of the awards presented in the first NRA matches were cash or firearms. Some of these firearms were heavily embellished works of art. In the very first match, a member of the 22nd New York Regiment took home a gold-mounted Winchester Model 1866 valued at $100 — big money for the time.
In the 1870s shooting competitions were social as well as sporting events. Ladies and gentlemen came to watch and cheer the winners. This illustration, originally from Harpers Weekly, portrays the shooters and the viewing gallery at the 1876 Grand Centennial Championship—the “Palma” Match.
The Leech Cup — A Gift from Ireland
The Leech Cup was created for the first meeting of the American and Irish shooting teams. The elaborate cup was presented by Major Arthur Leech, captain of the the Irish team, to the Amateur Rifle Club of New York. This masterpiece of Irish silversmithing was later given to the NRA in 1901 by the New York Club. Today, the Leech Cup is the oldest trophy offered in overall NRA competitive target shooting, awarded through the National High Power Long Range Championships.

The Wimbledon Cup
The Wimbledon Trophy was a gift from the NRA of Great Britain. It was given, as a gesture of sportsmanship, after the the U.S. Team was denied the ability to compete in England’s Elcho Shield match, then limited to Britain, Scotland, and Ireland. To maintain friendly competitive relations, the British presented the Americans with a large, engraved, lion-footed tankard trophy to be awarded each year to the Champion U.S. long-distance rifleman.
The Palma Team Trophy
Originally named the Centennial Trophy, in honor of the Centennial celebration of the independence of the United States of America, the Palma Trophy was commissioned from Tiffany’s at a cost of $1,500. The trophy was a full-sized replica of a Roman Legion standard, executed in bronze with silver and gold inlay. On the banner of the standard was the legend, “In the name of the United States of America to the Riflemen of the world”. Above the banner was an eagle, bearing in its talons a wreath of palm leaves and a plaque on which was the single word, “PALMA”, the Latin word for palm tree, which was used by the Romans to signify victory, or the ultimate in excellence.
Because the word Palma was so easily seen, the trophy soon became known as the “Palma Trophy”, and by 1878 was referred to officially by that name. The sriginal seven and one-half foot trophy is now lost, having not been seen since at least 1954. Serving in its place is a copy which was commissioned by Dr. Herbert M. Aitken of Eau Claire, WI. The copy was made from the original Tiffany blue-prints at a cost of $32,500. Dr. Aitken has given this copy of the Palma Trophy to the NRA for use in the Palma Match. The trophy is retained by the winning team until the next Palma Match.
In 2008, the Palma Trophy was returned to the NRA, and it was decided that the trophy, once refurbished, will travel to the host nation for the match every four years, then returned to the NRA for safekeeping.
The first competition for the Palma Team was a challenge match for which the British Commonwealth nations were invited. The match was fired in 1876 at the old Creedmoor Range on Long Island as part of the Centennial celebration of the United States. Teams representing Scotland, Ireland, Canada, Australia, and the United States took part. The match is currently fired on a four-year interval.

For the very first day of 2026 we present a precision rifle built with a modern 6mm cartridge — the 6GT. Developed by George Gardner of G.A. Precision and Tom Jacobs of Vapor Trail Bullets, the 6GT was designed to have the efficiency of a 6mm Dasher without the need for case forming. It was also designed with a longer case body so it feeds better from magazines. Even with the added capacity, the 6GT is still very efficient, and can achieve good velocities with less powder than a 6mm Creedmoor.
Today’s feature rifle was smithed and tested by Gavin Gear of UltimateReloader.com. Gavin did all the gunsmithing — chambering the barrel, fitting the muzzle brake, and even laser engraving the barrel. In building this 6GT rifle, Gavin used top-tier components: BAT TR action, Krieger 28″ 1:7.5″-twist 4-groove 6mm barrel, TriggerTech Diamond Rem 700-compatible trigger, and Area 419 Hellfire Muzzle Brake. The barreled action was then fitted in a handsome and rugged MDT ACC Chassis. On top is a Zero Tech 4.5-27×50mm FFP Trace Advanced scope in 30mm Hawkins Precision high rings.
We recommend you watch the video above — it covers the rifle build, load development, and then features some remarkable shooting sequences across snowy hills in the Pacific Northwest. Gavin’s team actually used a drone to capture overhead footage of the location.
After developing a promising load with Berger 109gr LRHT bullets, Varget powder, and Alpha brass, Gavin literally headed for the hills to test his new rifle at longer ranges, shooting from bipod. His load had shot well under half-MOA at 100 yards in testing so he was hoping he could hit multiple steel targets positioned at 340 yards, 760 yards, and 1000 yards. Indeed he did, proving the rifle’s great accuracy and Gavin’s fine trigger-pulling skills. You can see the hits at these time points in the above video:
340 Yards — 18:15 time | 760 Yards — 19:00 time | 1000 Yards — 19:54 Time
Gavin’s 6GT Hit Highlights on Steel out to 1000 Yards
Building Gavin’s 6GT Precision Rifle
Gavin Gear did all the gunsmithing on this project, using his own Precision Matthews TL-1660 lathe for the chambering with an Alpha carbide 6GT reamer. The barrel work took about four hours total. Shown below is the reamer cutting the chamber, which was finished with a 0.170″ freebore and 0.270″ neck diameter. For other brands of brass you might want the chamber to have a larger 0.272″ neck diameter.
Chambering the Krieger barrel with Alpha carbide 6GT reamer, 0.170” freebore, .270″ neck diameter.
This project when smoothly, with Gavin able to install the barreled action in the MDT Chassis and fit the buttstock in an hour or so. So total build time was about five hours. One nice “finishing touch” on the project was laser engraving the 28″ Krieger barrel — a process you can see in the video below.
Laser engraving of Krieger 28″ barrel.
About the 6GT — Sort of a 6 Dasher on Steroids
6GT Cartridge Design Features
The 6GT was designed to have an optimal length and capacity for mag-fed PRS/NRL tactical rifles. The 6GT is longer than a 6mmBR and 6 Dasher, but shorter than a 6mm Creedmoor and 6.5×47 Lapua. That gives the 6GT ample case body length to feed reliably from a magazine, while the case capacity is sufficient to run popular powders at reasonable pressures. It has a 35-degree shoulder angle.
On paper the 6GT seemed like the perfect cartridge for PRS- and NRL-style centerfire competition. It has the low recoil of a 6 Dasher, with good feeding and mag compatibility. With the 6GT, a competitor can push 6mm 105gr bullets at 3000+ FPS or run heavier bullets at ~2950 FPS. With this 28″ Krieger barrel, Gavin actually achieved 3004 FPS running 109gr Bergers.
Gavin started with quality Alpha Munitions brass. The cases were then annealed with an AMP Annealer and trimmed to length with a Henderson powered trimmer (see video below). After sizing with a Forster Co-Ax press, Federal SR Primers were seated using a Primal Rights competition seater. Next the powder was measured with an A&D FX120i force restoration scale. Finally, the Berger 109gr LR Hybrid Target bullets were seated with a Forster Micrometer die, again using the smooth Forster Co-Ax press.
Initial Load Testing with Berger and Hornady Projectiles
Before it got cold and snowy, Gavin did load development, shooting from a bench with a Sinclair front rest. The Krieger cut-rifled barrel was accurate right from the start and Hodgdon Varget powder proved to be a very good choice for the 6GT.
Gavin’s 6GT boasts a MDT ACC short action chassis with SRS-X Elite buttstock, vertical grip, and MDT CKYE-POD Bipod.
Gavin did initial load testing with both Hornady 110gr A-Tip Match and Berger 109gr Long Range Hybrid Target bullets. The Berger 109gr LRHT bullets were the most promising. A variety of charge weights were tested, with Gavin settling on 34.6 grains of Varget. This delivered fine accuracy with a 3004 FPS muzzle velocity. Group size measurements with this load are shown in the chart. At 100 yards, four three-shot groups averaged 0.361 MOA, and the rifle produced a nice 0.387 MOA (0.405″) five-shot group.

Can you hit an egg at 600+ yards? We mean hit it reliably — not just by luck. To do that you’ll need good shooting skills and a very accurate rifle. How accurate? Well, a chicken egg is, on average, 2 1/4 inches (57 mm) long and 1 3/4 inches (44.5 mm) in diameter. That means to hit an egg (on demand) at 600 yards, you’ll need a rifle capable of 1/3-MOA accuracy (or better). Forum member DukeDuke has such a gun, and he demonstrated its egg-busting prowess in this short video.
