This report from theU.S. Concealed Carry Association (USCCA)
As anxiety has grown around the COVID-19 pandemic in recent days, news reports from across the country have detailed how more and more Americans are embracing their right to self-defense and choosing to be their families’ ultimate protectors. Ammo.com reports, for example, that revenue from sales on its website increased 309 percent from February 23 through March 15, compared to a month before. Here are some recent media reports, tracking gun-buying trends:
The New York Times
Daniel Hill had never bought a gun before. But last week he was in Larry Hyatt’s gun store in North Carolina picking out two of them: a 9mm Taurus handgun and an AR-15 semi-automatic rifle. His motivation: the coronavirus.
Pittsburgh Post-Gazette
At gun shops, cash registers rang more like Christmas Eve than St. Patrick’s Day as firearms and ammunition sales soared through the roof Tuesday. Shop owners and managers cited customers’ concerns about home defense related to the COVID-19 pandemic.
The Arizona Republic
People in the U.S. are preparing for total anarchy amidst the growing COVID-19 concerns. Fear and panic are driving the gun-buying frenzy. Whatever the reason, gun sales are up everywhere — but particularly in states like California, New York and Washington that have been hit hardest by coronavirus, according to The Los Angeles Times.
The Denver Post
Some shops are selling twice as many firearms as on Black Friday while Colorado residents grapple with the novel coronavirus pandemic, disruptions to daily life and an uncertain future.
USCCA President Says New Gun Purchasers Should Get Training
The USCCA recommends that ALL new gun buyers receive training on the proper use of firearms, including essential safety procedures. USCCA President and Founder Tim Schmidt was recently a guest on Fox News with Tucker Carlson. Schmidt declared that: “Now more than ever, people understand they need to be their families’ first line of defense.”
Schmidt noted that gun ownership and self-defense demands responsibility. He encouraged all Americans — particularly first-time gun owners — to educate and train themselves: “So many — 90% — of these people buying guns have never owned guns before. They’ve probably never even touched a gun”. Schmidt said that proper training is vital for these new gun-owners: “I personally think that firearms ownership is a natural-born right of free people. But with that right comes a tremendous responsibility, and that responsibility is to be trained. [If you] just bought a gun for self-defense, get training.”
Here is the view from 9500 feet ASL. The SRS in 7mm Rem SAUM almost outran the Swarovski laser…
7mm RSAUM in a bolt-action bullpup? Yes it works. A talented shooter, who calls himself “ColdboreMiracle” in social media, has a Desert Tech SRS-A1 rifle chambered for the 7mm RSAUM, and it hammers. The 7mm Remington SAUM (Short Action Ultra Magnum) is popular with F-Open competition shooters. It can also work well for long-range hunting and tactical tasks. Learn more about the 7mm Remington SAUM in our 7mm Cartridge Guide.
ColdboreMiracle owns the SRS-A1 “covert” model, which has a shorter handguard than the standard SRS-A1 model shown below. Desert Tech now offers an SRS-A2 model which has an M-LOK handguard and some refinements to the chassis.
Here is a detailed video review of a Desert Tech SRS chambered in .308 Win. You can see a close-up of a 100-yard 5-shot group at time-mark 6:25:
Here is a review of the newer SRS-A2 Covert (shorter model), after 1000 rounds. The reviewer believe the SRS bullpup’s shorter length offers some advantages for precision shooters:
ColdboreMiracle says the bullpup design has many advantages: “The Stealth Recon Scout (SRS) rifle from Desert Tech is a bullpup-configured precision rifle with a shorter length than many carbines. The SRS has a multitude of barrel options that can be swapped in under a minute — all of them come with a 1/2-MOA accuracy guarantee and return to zero. The SRS’s bullpup design puts the rifle’s COG closer to the shoulder, making the rifle balance better off-hand. The straight-line geometry of the SRS makes recoil seem lighter, and barrel hop is reduced, allowing the shooter to stay on target better. It takes a little getting used to, when converting from a traditionally-configured bolt gun. But once you do, you won’t go back.” To learn more about this rifle (and other Desert Tech arms), visit ColdboreMiracle’s Facebook Page and YouTube Channel.
The 7mm RSAUM — Why It Was Chosen for this SRS
ColdboreMiracle explains how he selected the 7mm Rem SAUM chambering for his Desert Tech SRS Bullpup: “I just did a comparison between barrel life, velocity, brass, etc. and came to the SAUM. I can tell you this, if you go with one for your SRS, make sure you use long bullets like the 183 or 195, and seat them long. That will aid in smooth cycling.”
Mr. ColdboreMiracle tested the new generation 183gr Sierra MatchKings (item # 1983). These impressive projectiles are “tipped” at the factory. Claimed G1 BC is a lofty 0.707 (at 2300 fps and above). We have heard other reports that these bullets “hold waterline” exceptionally well at 1000 yards. That indicates the bullet-to-bullet BC is very consistent. No doubt the factory uniforming/pointing of the bullet tips helps in that regard.
As you can see, these 183-grainers shoot well in ColdboreMiracle’s SRS rifle. Here are five shots at 100 yards. That’s very impressive for a tactical-style rifle shot from a field-type bipod.
ColdboreMiracle says: “This is the only reason I need to shoot Sierra bullets. On the right (above) you can see the results of the 183gr SMK from my 7mm SAUM. Five shots at 100. A huge thanks to Mark at Short Action Customs, LLC for [chambering this barrel] for my Desert Tech SRS.”
7mm Remington SAUM — Key Considerations
In some respects, the 7mm SAUM cartridge may be better than the 7mm WSM. The 7mm SAUM holds less powder — but that’s a good thing, since the capacity is more than adequate to do the job. You can drive the 180s at 3000 fps with a SAUM using less powder than with a WSM. Additionally, the SAUM case has a slightly longer neck. This gives you greater flexibility in bullet seating. With a long neck you can set the throat so the long 180+ graing bullets are above the neck shoulder junction, yet you can still seat shorter hunting bullets close to the lands. Additionally, long case necks, some believe, cause less throat erosion than shorter necks. That’s not “hard science” but it is certainly a view shared by many experienced shooters. The long neck is one reason many varminters favor the 6mm Remington over the .243 Winchester.
7mm RSAUM Is More Efficient than 7mm WSM
7mm RSAUM shooter Steven Ikeeda tells us: “I decided that some type of 7mm was the ticket for doing well at 1000-yard matches, especially if one could drive the high-BC bullets at 2900+ fps. Looking over various 7mm cartridges that could produce those velocities (and didn’t require case-forming), I was impressed by the 7mm SAUM and the 7mm WSM. According to the load manuals, the 7mm WSM offered a bit more velocity than the 7mm SAUM. However, to achieve its small velocity advantage, the larger 7mm WSM had to burn 7-10% more powder than the 7mm SAUM. (The 7mm WSM has 81.0 grains of capacity vs. 73.6 grains for the 7mm SAUM.) The SAUM is a very efficient case. It looks like a 6.5×47 Lapua on steroids.”
The question of barrel break-in is controversial. Some folks advocate an elaborate, lengthy cycle of shooting and brushing, repeated many times — one shot and clean, two shots and clean and so on. This, it is argued, helps barrels foul less and shoot more accurately. Others say minimal break-in, with patching and brushing after 10-15 rounds, is all you need. Still others contend that break-in procedures are a total waste of time and ammo — you should just load and shoot, and clean as you would normally.
We doubt if there will ever be real agreement among shooters concerning barrel break-in procedures. And one must remember that the appropriate break-in procedure might be quite different for a factory barrel vs. a custom hand-lapped barrel. This Editor has found that his very best custom barrels shot great right from the start, with no special break-in, other than wet patches at 5, 10, and 15 rounds. That said, I’ve seen some factory barrels that seemed to benefit from more elaborate break-in rituals.
What’s the best barrel break-in procedure? Well our friend Eric Mayer of Varminter.com decided to ask the experts. A while back Eric interviewed representatives of three leading barrel manufacturers: Krieger, Lothar-Walther, and Shilen. He recorded their responses on video. In order of appearance in the video, the three experts are:
Do I Need to Break-In a New Rifle Barrel?
Eric Mayer of Varminter.com says: “That is a simple question, [but it] does not necessarily have a simple answer. Instead of me repeating my own beliefs, and practices, on breaking-in a new rifle barrel, I decided to answer this one a bit differently. While we were at the 2016 SHOT Show, we tracked down three of the biggest, and most popular, custom barrel makers in the world, and asked them what they recommend to anyone buying their barrels, and why they recommend those procedures. We asked the question, and let the camera run!” Launch the video above to hear the answers — some of which may surprise you.
Long-Term Barrel Care — More Experts Offer Opinions
Apart from the debate about barrel break-in, there is the bigger question of how should you clean and maintain a barrel during its useful life. Some folks like aggressive brushing, other shooters have had success with less invasive methods, using bore foam and wet patches for the most part. Different strokes for different folks, as they say. In reality, there may not be one solution for every barrel. Different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa).
“Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.
After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.” — Chip Lohman

This custom war wagon hauls varmint hunters around the Longmeadow Game Resort in Colorado.
Winter is behind us — it’s officially Spring. Today, March 19, 2020, is the Vernal Equinox, the official start of Spring. For many shooters, the coming of Spring means that it’s time to head out to the varmint fields. Here are eaidht items that can help ensure successful spring varmint adventures.
Eight Great Products for Varmint Shooters
1. BarrelCool In-Action Fan
Busy Varmint shooters may expend hundreds of rounds in a day. That’s tough on barrels. One way to extend your round count is to use the ingenious BarrelCool device. This little yellow gadget fits in your action with a blower tube that goes into the chamber. A small electric fan blows cooling air through the barrel. It really works — folks who’ve purchased the Barrel Cool and run temp strips on their barrel say the BarrelCool can significantly reduce the time it takes to cool down a hot barrel.
In the past, folks have tried various methods to cool barrels: water flushed through the bore, CO2 tanks, even battery-operated fish pumps. BarrelCool is a simpler, less costly, and much handier solution. Priced at $36.99, this small device can potentially can save you money by extending barrel life. To see how Barrelcool works, visit BarrelCool.com. There you’ll find video demos of BarrelCool units in both bolt-action and AR-type rifles.
2. Uncle Bud’s Bulls Bag Sandbag
On most varmint hunts we spend most of the time shooting from a portable bench with a pedestal-type rest (we like the SEB Mini). But it’s nice having a big, heavy X-Type sandbag rig also. These four-chamber designs, such as the Uncle Bud’s Bulls Bag, allow shooting from a truck hood or any flat surface. Some rifles with narrow fore-ends really benefit from the firm “hug” provided by these “butterfly” style sandbags. We like the 15″ Uncle Bud’s Bulls Bag, currently $71.99 at Brownells. Durable and well-made, it will provide years of service. There is also a 10″ version that is easier to carry. Forum member Stoner24mkiv likes a Bulls Bag for shooting from a vehicle. He also suggests: “[take] an adjustable bipod if you are going to do any walking. Have a fanny pack or backpack for extra ammo, water, bore-snake, etc. when you go on your walkabouts. Bring a Boonie hat for blocking the sun, sun glasses, sunscreen. High leather boots.”
3. Scope with Built-In Laser Rangefinder
The Burris Eliminator III is an impressive piece of electro-optical technology. With a push of a button, a built-in laser rangefinder senses the distance to your target and the Eliminator’s microprocessor instantly calculates the required hold-over based on your load’s ballistics. The calculated aiming point is then displayed in the reticle with an illuminated red dot on the vertical cross-hair. Just put the red dot on the target and make the shot. Easy as that. If you are working a large prairie dog field and constantly moving near to far and back again, this scope is really handy. Laze, adjust aim with the dot, and squeeze the trigger. Its that simple. We’ve used this scope out to 500 yards on small steel targets and it worked flawlessly.
4. Hornady 17 HMR V-Max 500 Round Brick, $89.99
For those distant prairie dog shots, you’ll want a centerfire round such as a 22 BR/BRA or 22-250. However, for closer work, or for smaller varmints such as ground squirrels, the 17 HMR is hard to beat. There are many good factory rifles chambered for the 17 HMR, such as the Savage A17. Right now Midsouth has a Hornady 17 HMR brick of 500 for a low price of $89.99. That works out to just 18 cents per round — cheap enough that you can blast sage rats all days long and never worry about running out of ammo.
5. Stick-On Temp Strips Monitor Barrel Heat
You never want your barrel to get too hot. Accuracy suffers when barrels over-heat, and excessive heat is not good for barrel life. So how do you monitor your barrel’s temperature? You can check if the barrel is “warm to the touch” — but that method is not particularly precise. There is a better way — using temperature-sensitive strips. McMaster.com (an industrial supply house) offers stick-on temp strips with values from 86° F to 140° F. A pack of ten (10) of these strips (item 59535K13) costs $12.77 — so figure it’ll cost you about $1.28 per barrel for strips. That’s cheap insurance for your precious barrels. For best barrel life, try to stay under 120 degrees F.
6. Low-Fouling Power for High-Volume Varmint Loads
For high-shot-count varmint safaris, you want a clean-burning powder that minimizes barrel fouling. While there are many great powders for the .223 Rem, we like Hodgdon CFE 223 for our high-volume varmint loads. This powder really seems to keep barrels cleaner. Originally developed for U.S. rapid-fire military systems, CFE 223 incorporates a proprietary chemistry named “Copper Fouling Eraser”. Based on tests with extended shot strings, Hodgdon claims that, by using CFE™223, match shooters, varmint hunters, and AR shooters can maintain accuracy for longer periods, with less barrel-cleaning time.
7. Bog Pod SB-2 Sportsman’s Bipod (21″-40″)
If you’re looking for a versatile, stable and easy-to-carry field support, check out the latest BOG-POD Series SB-2 Bipod. Featuring 21″-40″ adjustable legs, the BOG-POD Bipod can be used while sitting, standing, or kneeling. This kid of support is highly recommended for shooting on hills where a conventional bipod doesn’t offer enough elevation. This unit has a 360° swivel head and the legs adjust independently out to a 60-degree angle with adjustable tension to ensure maximum accuracy. Right now you can get this SB-2 Bipod for just $19.99 on Amazon — a great deal.
8. Motorola T100 Talkabout Radios
When you’re in the varmint fields, its essential to have good communications with your fellow shooters. You can’t count on cell coverage in the hinterlands so we recommend a good pair of Walkie-Talkies. The Motorola T100s have a very impressive range (up to 16 miles in ideal conditions), yet cost just $21.99 for the pair. These 22-Channel T100 Talkabouts will run up to 18 hours on three AAA batteries. Users have been very pleased with this inexpensive handheld radios.
Any long range shooter knows that wind is our ultimate nemesis. The best ways of overcoming wind are to measure what we can and use computers to calculate deflection. The Applied Ballistics Kestrel is a great tool for this. As good as our tools may be, we don’t always have them at our fingertips, or they break, batteries go dead, and so on. In these cases, it’s nice to have a simple way of estimating wind based on known variables. There are numerous wind formulas of various complexity.
The Applied Ballistics (AB) Wind Hack is about the simplest way to get a rough wind solution. Here it is: You simply add 2 to the first digit of your G7 BC, and divide your drop by this number to get the 10 mph crosswind deflection. For example, suppose you’re shooting a .308 caliber 175-grain bullet with a G7 BC of 0.260 at 1000 yards, and your drop is 37 MOA. For a G7 BC of 0.260, your “wind number” is 2+2=4. So your 10 mph wind deflection is your drop (37 MOA) divided by your “wind number” (4) = 9.25 MOA. This is really close to the actual 9.37 MOA calculated by the ballistic software.
WIND HACK Formula
10 mph Cross Wind Deflection = Drop (in MOA) divided by (G7 BC 1st Digit + 2)
Give the AB wind hack a try to see how it works with your ballistics!
Some Caveats: Your drop number has to be from a 100-yard zero. This wind hack is most accurate for supersonic flight. Within supersonic range, accuracy is typically better than +/-6″. You can easily scale the 10 mph crosswind deflection by the actual wind speed. Wind direction has to be scaled by the cosine of the angle.
This story, from our Gun of the Week Archives, offers a good intro to the 30 BR cartridge, which is still the leading chambering for short-range Score Benchrest.
What’s better than one custom-built 30 BR with gorgeous wood and top-shelf components? A matching pair of course. Just ask Australian shooter Greg Roche (“Caduceus” in our Forum). A decade ago, Greg spent two years living and working in the USA. While in America, he commissioned two matched custom rifles to bring back to Australia for Hunter Class BR matches. Though the look-alike rigs are both chambered in 30 BR, one is designed for the Australian “Traditional” centerfire Hunter Class (10-lb limit), while the other is purpose-built for the “Custom” centerfire Hunter Class (14-lb limit). The 10-lb Traditional rifle features a fully-functioning two-round magazine and a 6-power scope. In contrast the Custom Class rifle is a single-shot action, with a 45X Leupold scope. The Custom weighs 13.5 pounds so it can also be used in traditional Heavy Varmint Benchrest matches if desired.
Tale of Two Rifles Story and Photos by Greg Roche (“Caduceus”)
The USA boasts some of the finest precision rifle-builders and Benchrest parts suppliers in the world. Before returning to Australia after two years in the States, I decided to have two special BR rifles built using American components and skilled labor. I wanted a matched pair — twin guns that would be as handsome as they were accurate. The heavier gun of the pair, the 13.5-lb Custom Class rifle, features top-of-the-line (but well-proven) technologies and components. With the 10.5-lb Traditional Class rifle, we had to develop new solutions to allow the 30 BR cartridge to feed from a functional two-round magazine. Here is my saga of how my twin 30 BRs were conceived and built, and how they have performed in competition.
BACKGROUND — The 30 BR for Score Competition
The 30 BR is a wildcat cartridge based on a necked-up version of the 6mmBR Norma case. It originated in U.S. Benchrest circles where it found its niche in Varmint For Score (VFS) matches. Unlike traditional Benchrest, where group size determines the winner, VFS matches are shot on a target with multiple, concentric-ringed bullseyes. Point total is based on “best edge” shot location (one shot per bull). In score competition, the 30 BR’s “supersized” .308-diameter hole offers an advantage over the 6mm hole created by a 6 PPC, the dominant group BR chambering.
The starting point for loading the 30 BR wildcat is Lapua 6mmBR brass. These are necked up as a single-step operation using a .30 caliber tapered expander ball (or dedicated expander mandrel). This will leave a bulge in the neck, so the expanded case neck is normally turned to bring the thickness down to the correct dimension for the chamber. I turned these necks down to .010″ wall thickness using a Stiller neck-turning tool. It features an eccentric mandrel similar to the Nielson “Pumpkin”. Loaded rounds measure .328″ neck diameter. This gives minimum clearance in my .330″ neck chamber, so very little neck resizing is needed after firing. Cases are trimmed to 1.500″ prior to turning to ensure consistency since the Stiller tool indexes the length of cut off the case mouth. Other than that, cases are just chamfered, loaded and made ready to shoot. No special fire-forming is required.
17-Twist Barrels for Both Rifles
Texan gunsmith Mike Bryant chambered both barrels. Mike also polished both barrels to a high-gloss to match the receivers. In this game, barrels are consumables, much like powder and primers, so most owners wouldn’t bother to polish their barrels. However a 30 BR barrel can provide up to 5000 rounds of accurate life (unlike a 6PPC barrel which might be tossed after 800-1000 rounds.) So, these barrels are likely to be on the rifles for many seasons. Given the high-gloss finish of the Grizzly actions and the beauty of the Red Cedar stocks, it would have been an injustice to leave a dull finish on the barrels.
The chambers were both cut with the same reamer supplied by Dave Kiff of Pacific Tool and Gauge. Randy Robinett, one of the originators of the 30 BR wildcat, specified the reamer dimensions. Randy’s 118gr, 10-ogive custom BIB bullets and the 30 BR cartridge enjoy a winning track record in the USA. The 30 BR Robinette reamer has zero free-bore and a .330″ neck, and is optimized for the BIB 118s. The bullets perform best when seated far enough out to jam firmly into the rifling as the bolt is closed. The long ogive means the bullet’s bearing surface is very short.
Slow Twists for Maximum Accuracy
You may note the unusually slow twist rate of both barrels. In most .30-caliber chamberings, the barrel twist rate is 1:11 or 1:12 to stabilize 150gr to 200gr bullets. The 30 BR is optimized for 115gr to 118gr flat-base bullets and 1:17 provides sufficient stability at muzzle velocities around 2900-3000 fps. In competitive Benchrest, where every thousandth of an inch counts, over-stabilization of projectiles can hurt accuracy, so “just stable enough” is the goal; hence the 1:17 twist.
Case Forming, Case Prep, and Reloading Methods
A Sinclair case neck micrometer indicates neck thickness of 0.010″ after neck turning.
30 BR dies are readily available from a number of manufacturers. I personally use Wilson neck and seating dies with a Sinclair Arbor press, but Redding and Forster both supply high-quality threaded dies for use in a conventional press. For under $100.00 US, custom full-length dies can be obtained from Hornady and CH Tool & Die by sending them reamer prints or a couple of fired cases. Harrell’s Precision offers “semi-custom” dies. Just send them some fired cases and they select a pre-made CNC-cut die that ideally fits your chamber. You can ask the Harrell brothers for a die that’s tighter at the shoulder or base, or otherwise customized to your preferences.
Load Development and Accuracy Testing
With cases formed and bullets selected, load development is simply a matter of choosing the right primer, powder and charge weight, and loading the most consistent ammunition possible. The Lapua BR cases use a small rifle primer. The choice here was Federal 205 Match primers vs. CCI BR4 Benchrest primers. Some shooters have also had success using CCI 450 Magnum primers but it is very unlikely the small case needs this much spark to light off regular extruded powders. In my case, I selected Federal primers because availability tends to be better in Australia.
The relatively large bore-to-capacity ratio of the 30 BR case means that fast burning powders are the order of the day. Once again, US experience suggests H4198 (the Hodgdon equivalent of ADI AR2207) is the choice of match winners. The fact that H4198/AR2207 is an Australian-made product is an added bonus. So, I loaded up test rounds with AR2207 from 32.5 grains to 35.0 grains in approximately 0.3 grain increments. All bullets were seated to jam +0.010″ into the lands. This places the bullet base about two-thirds of the way down the neck and well short of the neck-shoulder junction.
Probably the most popular centerfire rifle round in the Western Hemisphere is the .223 Remington and its metric match, the 5.56x45mm. Though many folks use “.223 Rem” and “5.56×45″ interchangeably, there are some meaningful differences in specifications for the original .223 Rem and the 5.56x45mm cartridge, as adopted by the U.S. military and NATO armies. The default chamber throats are slightly different and the .223 Rem is rated at 55,000 PSI vs. 62,366 PSI for the 5.56x45mm.*
.223 Rem vs 5.56x45mm — Key Differences
There is a truly outstanding, very thorough article on the subject, published by LuckyGunner.com.** This involved extensive testing, with pressure monitors, of 5.56x45mm ammo in .223 Rem chambers. Those tests revealed the peak pressures. Here is one of the ammo test charts:
NOTE: “The observed chamber pressure for Federal XM855 5.56mm ammunition in a .223 Rem chamber exceeded .223 maximum pressures, but not by a massive amount. The ninth shot (the red line) was an underpowered cartridge which exhibited significantly lower velocity and pressure than the other rounds, so it was excluded from the average velocity and pressure numbers for this chamber.”
And if you’re curious, LuckyGunner also fired .223 Rem ammo in a 5.56x45mm NATO-chambered AR15 rifle. As you would expect, the peak pressures were significantly lower, but the .223 Rem ammo still cycled the semi-auto AR-platform rifle perfectly well:
UltimateReloader.com Explains .223 Rem vs. 5.56x45mm
To explain the key differences between the .223 Rem and 5.56x45mm cartridges our friend Gavin Gear of UltimateReloader.com has created a very thorough 12-minute video. This covers the cartridge specifications and explains key considerations for hand-loaders. Gavin also addresses the oft-asked question “Can I shoot 5.56x45mm ammo in my .223 Rem chamber?” Gavin’s video is definitely worth watching. In fact, this is one of the most popular videos Gavin has ever created — it has been watched over 300,000 times on YouTube.
What Exactly Is the 5.56x45mm NATO Cartridge?
The 5.56×45mm NATO is a rimless bottle-necked intermediate cartridge family standardized by NATO with development work by FN Herstal. It consists of the SS109, SS110, and SS111 cartridges. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries.
Bullet diameter: 5.70 mm (0.224 in)
Maximum pressure (EPVAT): 430.00 MPa (62,366 psi)
Maximum pressure (SCATP 5.56): 380.00 MPa (55,114 psi)
Case length: 44.70 mm (1.760 in)
Rifling twist: 178 mm or 229 mm (1 in 7 in)
Parent case: .223 Remington (M193)
Ammo-Maker Federal Premium Compares .223 Rem and 5.56x45mm
Here is a video from ammo-maker Federal Premium explaining the difference between .223 Remington and 5.56x45mm NATO. Federal states that you may experience excessive pressures when firing a 5.56x45mm in a standard .223 Remington chamber:
One leading gunwriter has addressed the question of shooting 5.56x45mm ammo in .223 Rem chambers. He advocates caution (for more info, SEE pressure tests by LuckyGunner.com):
“I have received a slew of questions — many from first time AR-type rifle buyers — about the .223 Rem and the 5.56×45 mm NATO cartridges. Can I shoot 5.56×45 mm NATO in my .223 and vice-versa? Are these the same cartridge?
Externally, the two cartridge cases are identical. The main differences are that 5.56×45 mm NATO operates at a higher chamber pressure (about 60,000 PSI versus 55,000 PSI on the .223 Rem.) and the 5.56’s chamber is slightly larger than that of the .223 Rem. Also, the throat or leade is longer in the 5.56×45 mm chamber. What does this mean? You should not shoot 5.56×45 mm NATO out of a rifle that is chambered in .223 Rem. And be aware that some .223 Rem. ammunition will not reliably cycle through some AR-style .223 Rem. rifles, but it usually does. As a matter of fact, I have not encountered any difficulty with current .223 Rem. loads cycling through a 5.56 mm AR-style rifle.” – Mark Keefe, Editor, American Rifleman
* According to the official NATO proofing guidelines, the 5.56×45mm NATO case can handle up to 430.0 MPa (62,366 psi) piezo service pressure. The U.S. SAAMI lists Maximum Average Pressure (MAP) for the .223 Remington cartridge as 55,000 psi (379.2 MPa) piezo pressure with deviation of up to 58,000 psi (399.9 MPa). The chamber for military 5.56×45mm NATO has a longer throat prior to the bullet contacting the rifling which results in lower pressures when firing 5.56×45mm NATO ammunition. If 5.56×45mm NATO is used in rifles chambered for .223 Remington the bullet will be engraving the rifling when chambered. which can increase pressures past SAAMI Max levels. NOTE: The C.I.P. standards for the C.I.P. civilian .223 Remington chamber are much closer to the military 5.56×45mm NATO chamber.
** The full-length LuckyGunner article is well worth reading. It even provides specifications for a number of .223 Rem reamer types, and compares the original .223 Rem, the 5.56x45mm NATO, and the modern .223 Wylde chamberings.
Firing an “off-the-rack” M1903 Springfield that he had never shot before, using GI-issue “tin-plate” ammunition, George Farr shot 71 consecutive bullseyes at 1000 yards (70 for record), setting a marksmanship record that has never been broken.
This is not the typical Daily Bulletin feature. It is an historical account of one of the greatest performances by a marksman in the history of the National Matches at Camp Perry. We think any competitive shooter will find this amazing narrative worth reading from beginning to end. This story is provided courtesy the NRA Blog with photos supplied by the NRA Museums.
An Old Man at the National Matches:
‘Dad’ Farr’s Golden Afternoon at Camp Perry by Doug Wicklund, NRA Museums Senior Curator
It was 1921. Warren Harding was President of the United States, and “The War to End All Wars” was less than three years past. The nation was getting back to a normal routine, and for competitive shooters, that meant an annual pilgrimage through the state of Ohio to the shores of Lake Erie, where the National Matches had been held since 1907 at Camp Perry. In those lighter days of the “Roaring Twenties”, marksmen from states banded together to make the journey, housing together in tent clusters on green lawns well behind the firing points.
The silver plate affixed to George Farr’s M1903 Springfield states: “With this rifle and using issued ammunition Mr. G.R. Farr of Seattle Wash in the Wimbleton Match, 1921, Camp Perry O., made 71 consecutive bulls eyes at 1000 yards”.
But one man at the 1921 National Matches stood out amongst the rest. George “Dad” Farr was a 62-year-old man from the state of Washington, and this was his first time heading east to shoot in the “big leagues”, as some of his fellow Evergreen State friends termed the annual competitions.
Aptly nicknamed, “Dad” was a good bit older than the average shooter during that late summer season, striding forward hesitantly clad in a khaki shirt and dungarees. He wasn’t a practiced High Power shooter — he showed up at Camp Perry without a rifle, and relied on a crude monocular for a spotting scope that he had fashioned from a pair of French opera glasses.
At the previous day’s shooting, he had experienced issues with the initial .30-06 rifle he had chosen from the rack, a Model 1903 Springfield that didn’t seem to hold a consistent zero. This day, he chose a different gun, just another off-the-rack rifle no different from the one next to it. Though he didn’t realize it, George Farr had just made the best selection of his life.
Farr readied his bolt-action and prepared a clip of five rounds of Government Issue ammunition, then went to his position. He was ready to fire on a 1,000-yard target with a rifle he had never shot before.
Perhaps he had resigned himself somewhat to the outcome — after all, it was the last relay of the day on September 9. Off to the west, the sun was beginning its slow trip down to the horizon. But Farr shouldered his Springfield and prepared to fire. The time was 4:30 p.m. Shooters nearby were puzzled by this shooter who squirmed and shifted repeatedly, but were amazed as he made his first hits on paper. Farr was shooting Frankford Arsenal tin-plate ammunition, the standard G.I. .30-06 rounds. More experienced marksmen, like Marine Sgt. John Adkins — who had just won the Wimbledon Cup — were using commercial Remington match ammunition and had spurned the government ammo.
The Historic String of Bullseyes
At that distant 36-inch target, Farr scored two hits for his two sighters, with the last sighter being a bullseye. He then prepared to fire 20 shots for record. Each of those 20 shots went into the center. Each scored as a “5”. At the end of this amazing string, Farr gathered up his monocular and prepared to depart. His fellow shooters quickly advised that match rules required him to continue firing until he missed “the black”, the inner 5-Ring bullseye at the center of the target. Farr had only brought one box of ammunition with him to the firing line, and had run out. As he waited for more of the tin-plate ammo he had been using, the sun continued its retreat. Farr continued his shooting, racking up growing strings of bullseyes – 30, 40 50, 60 – each impact on target being carefully recorded on his scorecard in the growing darkness.
Then, at the 71st shot with daylight completely gone, the bullet strayed outside the target center, and Farr’s incredible string came to its conclusion. But counting his second sighting shot, George Farr had fired 71 consecutive bullseyes at 1,000 yards using an unfamiliar rifle plucked from an ordnance rack earlier that day. It was an amazing feat, one immediately recognized by those in attendance. His fellow shooters quickly took up a generous collection, contributing in recognition of Farr’s natural skill and enabling him to purchase that bolt-action Springfield he had worked magic with on that distant target. Enough funds remained that a silver presentation plate, inscribed with the names of the states whose competitors had contributed, was ordered and mounted on the side of the rifle’s buttstock.
The next year, the Civilian Team Trophy was re-designated as the Farr Trophy, and George Farr’s record, fired on the old target system, was never beaten. Farr’s rifle went home with him to Washington and remained there, never again traveling eastward to Camp Perry. In 2011, The Farr family donated this legendary piece of shooting history to the NRA National Firearms Museum collection.
In 2013, as NRA Museums curators began assembling the collection for display at the NRA National Sporting Arms Museum at Bass Pro Shops in Springfield, Missouri, the museum staff created a unique exhibit featuring George Farr’s Model 1903 Springfield rifle and its special place in competitive shooting history. Alongside the rifle rests Farr’s simple monocular, another mute witness to Camp Perry history made on that September evening in 1921.
Farr’s Springfield… is one of thousands of historically significant firearms found in the NRA Museums collections on display across three locations. To view the collection and learn more about the incredible stories behind each gun, visit the NRA Museums in person or browse the NRA Museums website.
The new generation Berger LRHT Match bullets come with Meplat Reduction Technology™ (MRT) for more consistent BCs. Essentially they are “pointed” at the factory. Likewise, many of Sierra’s most popular MatchKing bullets are now factory-pointed in a final production stage. However, for most other bullet types, you can benefit from using a bullet pointing system to make the meplats more consistent.
Gear Review by GS Arizona
This article originally appeared in the Rifleman’s Journal website.
Many of you have doubtlessly read Bryan Litz’s articles in our Daily Bulletin and on his Applied Ballistics website about various current long-range bullets. Bryan’s work carries a great deal of weight in the world of ballistics, so his comments (and mathematical proofs) regarding the benefits of bullet pointing certainly caught my attention. Bullet pointing, like meplat trimming, is an effort to reduce the ballistic inconsistency created by the somewhat jagged tip of the jacket where the bullet forming dies bring it to a point in the manufacturing process. Of course, we could eliminate this problem altogether by shooting closed-tip, open-base bullets like the Lapua D46, but that merely shifts the jacket problem to the other end of the bullet.
In any event, hollow point bullets rule the accuracy world today, so John Whidden, multi-time National Long Range Champion and a talented gunsmith to boot, came up with a very handy tool to let us make those hollow points pointier. Let’s have a look at John’s tool and see how it works.
The Whidden Bullet Pointing Die System uses a Forster bullet seating die body as its basic structure and that’s a good choice given the quality machining Forster does on these. The real heart of the tool comes in two parts: the caliber sleeve and the pointing die that fits inside the sleeve. In fact, to point up different caliber bullets, you only need to change the caliber sleeve, everything else remains the same. The last item is the bullet base that slips into a standard .308 shellholder and supports the bullet as it goes into the die body.
It took me less than five minutes to get everything set up, including changing the caliber sleeve from 6mm to .30 caliber. John’s instruction sheets are well illustrated and clearly written; you should have no problem getting up and running.
Pointing the bullets is as easy as sizing a piece of brass. You can see in the second photo above the difference between a few pointed bullets and a few un-pointed ones. The innermost pointed bullet in the picture was my first attempt and I adjusted the die a little after that, you can see that the others are closed a little more. John even includes a couple of sample bullets so that you can see one done right and one done wrong. That is a nice addition that can help you achieve the desired results.

I think Bryan’s work supports the validity of this concept and John’s tool puts it into practice in a simple-to-use manner that makes it just about impossible to do any damage to the bullet. I have shot pointed bullets in various calibers at many matches now. Pointing is not a “miracle cure”, but I believe that pointing bullet tips can produce long-range accuracy gains, through reduced vertical dispersion, for many popular types of match bullets. The Whidden Bullet Pointing Die System retails for $220.00 (with one insert). Additional die inserts are $42.00 each. Extra caliber sleeves are also $42.00. You can purchase directly from Whidden Gunworks, or from Sinclair International.
In some respects, the 7mm SAUM cartridge may be better than the 7mm WSM. The 7mm SAUM holds less powder — but that’s a good thing, since the capacity is more than adequate to do the job. You can drive the 180s at 3000 fps with a SAUM using less powder than with a WSM. Additionally, the SAUM case has a slightly longer neck. This gives you greater flexibility in bullet seating. With a long neck you can set the throat so the long 180+ graing bullets are above the neck shoulder junction, yet you can still seat shorter hunting bullets close to the lands. Additionally, long case necks, some believe, cause less throat erosion than shorter necks. That’s not “hard science” but it is certainly a view shared by many experienced shooters. The long neck is one reason many varminters favor the 6mm Remington over the .243 Winchester.
Do I Need to Break-In a New Rifle Barrel?
30 BR dies are readily available from a number of manufacturers. I personally use Wilson neck and seating dies with a Sinclair Arbor press, but Redding and Forster both supply high-quality threaded dies for use in a conventional press. For under $100.00 US, custom full-length dies can be obtained from
