NEW PRODUCT REPORT by Dennis Santiago
At the recent Western CMP Games and Creedmoor Cup Matches in Phoenix, I received a box of the all-new .30-06 Match-Grade ammunition from Dennis DeMille of Creedmoor Sports. My job was to test the ammo (at the Games) and write about it. This box was part of Creedmoor’s 3-million-round production run for the Civilian Marksmanship Program (CMP). CLICK HERE for Ammo Sales.

The new .30-06 “Match-Grade” ammunition from Creedmoor is impressive. This ammo is made from top-quality components: brand new Lapua .30-06 brass and 167gr Lapua Scenar bullets. The ammo, optimized for 200-yard CMP Games tournaments, runs at 2720 fps. DeMille says the Standard Deviation (SD) is very tight with this ammo — comparable with precision hand loads. The low SD reflects great attention to detail in ammo assembly. Creedmoor’s industrial loader is run at half-speed to improve consistency. Charges are thrown precisely — I believe in two (2) half-charges.
When you hold the ammunition up to the light, each round appears a perfect clone of each other round — something that cannot be said for some other factory ammo (even so-called “match ammo”). This is about a close as one is likely to get to a precision hand load. The good news is that Creedmoor plans to produce similar ammunition in other chamberings.
The economics of the ammunition are equally intriguing. This ammo is being sold by the CMP for $1.30 per round. Think about that — new .30-06 Lapua brass sells for around $100.00 per hundred cases. So, you get to fire a precision match round for about 30 cents and have premier once-fired brass for future use. The price per rounds tells me that CMP isn’t making money on this — it is being sold at near cost to promote marksmanship.
Great Ammo at a Great Price
In offering this new .30-06 ammo at an affordable price, the CMP is making it possible for non-reloading competitors to have the same quality of ammunition as those who handload with premium components. This will be a major improvement for shooters of m1903s and M1 Garands. I think this ammo can be real equalizer for those who do not currently hand-load their own .30-06 ammunition. The CMP and Creedmoor Sports are to be commended for collaborating on this game-changing product introduction.
Where to get the Creedmoor Sports CMP .30-06 Ammo
The CMP is now selling the Creedmoor-produced .30-06 ammo on the CMP website, item #4C3006CS167-100 (click the “e-Store” button to launch shopping cart). The retail price is $130.00 per 100-round case (i.e. two boxes). That works out to $1.30 per round.*
.30-06 Ammo Performance
When someone hands you a box of ammo with a challenge how can you not throw all your match plans out the door and play? I was planning to fire the CMP GSM match with my M-1 Garand the next day using 150gr SMK handloads but I said, “What the heck. Let’s go for it.” You get five sighters in a GSM match which is plenty to zero with new ammo.
The ammo is optimized for shooting 200-yd CMP matches with rifles like my as-issued DCM M-1 Garand.
I shoot the M-1 Garand matches with a rebuilt 5-digit receiver gun with a 1950s barrel refurbished at Anniston Armory that I got from the DCM back in the day when the postman delivered them. It shoots true and has garnered its share of Western Games trinkets over the years including a number of golds and one of those coveted M-1 EIC 4 points medals. It’s a good platform for the test. Sighters revealed the Creedmoor ammo shoots about two minutes higher impact versus my pet load. The tale of the tape said 96-2X slow prone, 93-1X rapid prone and 81-1X offhand totaling 270-4X. The DCM machine took home a bronze in 2014.
Accuracy and Consistency
This Creedmoor ammo is indeed amazingly consistent. The slow prone stage was a pure joy to shoot. This ammunition is “brutally honest”. It will reveal every little error you make be it defocusing on your front sight drenching in sweat under the Phoenix sun, not being fast enough to reset your NPA mid-string in your rapid as the big gun moves you around or just being jittery on your feet during the back half of your offhand. With this ammo I felt confident to trust that any error was mine after each shot. There was no wondering about the ammo. I knew its feedback was accurate. That is a huge thing to be that confident in one’s gun and ammunition. I never felt that confident with HXP or even my handloads. If anything, I now know that even my ammo for the M1 Garand and M1903A3 will benefit from the same careful case preparation and assembly as my tactical rifle or long range ammo.
*At the Western CMP Games this Creedmoor .30-06 ammo was sold at a discounted price of $1.15 per round. That’s an example of the great deals one can get by attending CMP competitions.

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

Readers often ask us: “Is there an inexpensive way I can get started in position shooting?” The answer is “yes” — across the country CMP-affiliated clubs host Rimfire Sporter matches. You can use a wide variety of .22LR rimfire rifles — manual actions (such as a Winchester model 52) or semi-automatics (such as a Ruger 10/22). There are prone, sitting/kneeling, and standing stages. CMP rules provide separate classifications for scoped rifles, open-sighted rifles, and aperature-sighted rifles. The matches are fun, the ammo is inexpensive, and everyone has a good time while improving their marksmanship.
Our friend Dennis Santiago recently helped run a CMP Rimfire Sporter Match in Southern California. Dennis reports: “You want something challenging? Well that X-Ring 50 yards away is the diameter of a 50 cent piece, and there are people out there that can womp that thing with iron sights.”
The rapid-fire sitting or kneeling stage of a CMP-sanctioned .22 Sporter Match consists of two, 5-shot strings. A manually-operated or semi-automatic rifle may be used for this match. Below is a video Dennis made that shows a sitting/kneeling rapid fire stage.
Dennis notes: “There are six (6) stages of fire on a tough little target. Notice the rifles that can be used run the gamut from pump and bolt actions to variations on the semi-auto theme. All still require a good eye and a steady hold to earn one’s bragging rights for the day. A match takes about an hour and a half per relay. The slowest part of the match is initial sighting in. It’ll take longer than the allocated 5 minutes for the typical first timer coming to a club match.”
At Dennis’s Burbank Rifle & Revolver Club (BRRC), procedures are modified a little bit: “What we typically do at BRRC is run two relays. Experienced competitors shoot per the full rulebook. New shooters are afforded a bit more relaxed environment to make the experience more fun and inviting. We do the same thing in our M-1 Garand Clinic/Match series.”
Rimfire Sporter Match Basics
The CMP Rimfire Sporter Rifle Match is an inexpensive, fun-oriented competition using .22 caliber sporter rifles (plinking and small game rifles) commonly owned by most gun enthusiasts. To compete, all you need is a basic rifle, safety gear, and ammunition. No fancy, high-dollar rifles are required.
The event is shot with standard sporter-type, rimfire rifles weighing no more than 7 ½ lbs, with sights and sling. Rifles may be manually-operated or semi-automatic. Shooters with manually-operated actions are given extra time in the rapid-fire stage to compensate for the difference. (See Video).
There are three classes of competition — the standard “O Class” for open-sighted rifles, “T-Class” for telescope-sighted and rear aperture-sighted rifles and “Tactical Rimfire” class, which is a .22 caliber A4 or AR15 style rifle. Firing for all classes is done at 50 and 25 yards on a target with a 1.78″ ten-ring and an 18″ outer one-ring. Even new shooters can get hits on this target, but it’s still tough enough that no one yet has fired a perfect 600×600 score.
The Civilian Marksmanship Program (CMP) has a CMP Guide to Rimfire Sporter Shooting. This FREE, 50-page digital publication covers equipment, positions, course of fire, rules, scoring and much more. You’ll find helpful “how-to” sections on aiming, sight picture, hold control, and trigger control. Reading these instructional sections can benefit any prone or three-position competitive shooter.

In discussions of ballistics, you’ll see references to “tangent” and “secant” bullet shapes. We know that, for many readers, these terms can be confusing. To add to the confusion, bullet makers don’t always identify their projectiles as secant or tangent designs. This article provides a basic explanation of tangent and secant designs, to help you understand the characteristics of both bullet shapes.
Tangent vs. Secant vs. Hybrid
Most match bullets produced today use a tangent ogive profile, but the modern VLD-style bullets employ a secant profile. To further complicate matters, the latest generation of “Hybrid” projectiles from Berger Bullets feature a blended secant + tangent profile to combine the best qualities of both nose shapes. The secant section provides reduced drag, while the tangent section makes the bullet easier to tune, i.e. less sensitive to bullet seating depth position.
Berger Bullets ballistician Bryan Litz explains tangent and secant bullet ogive designs in a glossary section of his Applied Ballistics website, which we reprint below. Bryan then explains how tangent and secant profiles can be combined in a “hybrid” design.
How Bullet Ogive Curves are Defined
While the term “ogive” is often used to describe the particular point on the bullet where the curve reaches full bullet diameter, in fact the “ogive” properly refers to the entire curve of the bullet from the tip to the full-diameter straight section — the shank. Understanding then, that the ogive is a curve, how is that curve described?
LITZ: The ogive of a bullet is usually characterized by the length of its radius. This radius is often given in calibers instead of inches. For example, an 8 ogive 6mm bullet has an ogive that is a segment of a circular arc with a radius of 8*.243 = 1.952”. A .30-caliber bullet with an 8 ogive will be proportionally the same as the 8 ogive 6mm bullet, but the actual radius will be 2.464” for the .30 caliber bullet.
For a given nose length, if an ogive is perfectly tangent, it will have a very specific radius. Any radius longer than that will cause the ogive to be secant. Secant ogives can range from very mild (short radius) to very aggressive (long radius). The drag of a secant ogive is minimized when its radius is twice as long as a tangent ogive radius. In other words, if a tangent ogive has an 8 caliber radius, then the longest practical secant ogive radius is 16 calibers long for a given nose length.”
Ogive Metrics and Rt/R Ratio
LITZ: There is a number that’s used to quantify how secant an ogive is. The metric is known as the Rt/R ratio and it’s the ratio of the tangent ogive radius to the actual ogive radius for a given bullet. In the above example, the 16 caliber ogive would have an Rt/R ratio of 0.5. The number 0.5 is therefore the lowest practical value for the Rt/R ratio, and represents the minimum drag ogive for a given length. An ogive that’s perfectly tangent will have an Rt/R ratio of 1.0. Most ogives are in between an Rt/R of 1.0 and 0.5. The dimensioned drawings at the end of my Applied Ballistics book provide the bullets ogive radius in calibers, as well as the Rt/R ratio. In short, the Rt/R ratio is simply a measure of how secant an ogive is. 1.0 is not secant at all, 0.5 is as secant as it gets.
Hybrid Bullet Design — Best of Both Worlds?
Bryan Litz has developed a number of modern “Hybrid” design bullets for Berger. The objective of Bryan’s design work has been to achieve a very low drag design that is also “not finicky”. Normal (non-hybrid) secant designs, such as the Berger 105gr VLD, deliver very impressive BC values, but the bullets can be sensitive to seating depth. Montana’s Tom Mousel has set world records with the Berger 105gr VLD in his 6mm Dasher, but he tells us “seating depth is critical to the best accuracy”. Tom says a mere .003″ seating depth change “makes a difference”. In an effort to produce more forgiving high-BC bullets, Bryan Litz developed the hybrid tangent/secant bullet shape.

This Wednesday, October 29, Shooting USA TV features the Bushnell Brawl, a tactical competition that draws top long-range shooters from the military, law enforcement and the civilian shooting communities. The match is held at the famed Rifles Only range in Kingsville, Texas. The Brawl is a one-of-a-kind physical and mental challenge — 20 events test each shooter’s ability to read wind, figure ballistics, and adapt to difficult shooting scenarios. And, each year, the competition proves to be even more challenging. There is even a helicopter stage.
“Whenever the difficulty ramps up, they step up, and we’ve seen it for the last fifteen years doing matches,” says Rifles Only Director, Jacob Bynum. “Ramp up the difficulty, quality goes up.”
The signature event is Trench Warfare, where each competitor gets a chance to shoot from a helicopter before running to the trench. Competitors also shoot from the tower, where shots are out to 1,000 yards. Not all events are shot over long distance. The Five Dot Drill and Know Your Limit on paper are shot inside 100 yards.

Hey guys here’s a torture test video that’s really worth watching — you’ll be shocked and amazed (we guarantee it). In this video, Nightforce Exec Kyle Brown (with help from NF employee Sean Murphy), absolutely brutalizes a Nightforce NXS 5.5-22x56mm scope. He bangs it on a concrete bench-top, throws it 50 yards downrange, knocks it on a hardwood beam multiple times, and then heaves it back again. We kid you not. To our eternal surprise, the Nightforce scope survives all that abuse and shoots fine. What did Timex once say — “Takes a licking and keeps on ticking”?
You’ve got to watch this video — it was shot with five cameras and runs with no “time-outs”, cutaways, or video tricks. What you see is what you get. This is one tough NXS. Thank you Kyle Brown and crew for taking the time to prove the durability of Nightforce Optics products.
Talented 3-position shooter (and trick-shot artist) Kirsten Joy Weiss says that any day at the range is “always a good day”. Here is her photo to prove it. If that shot doesn’t motivate you to spend a day outdoor with rifles, we’re not sure what will…
“Always a good day…” — Kirsten Joy Weiss
Editor’s Comment: We agree with Kirsten that a day at the range is “always a good day”, except well, er, when you ventilate your chronograph, or leave your bolt at home, or load the wrong ammo, or drop a steel gong on your foot, or have a dead battery in your car, or forget the gate lock combination. If you shoot often enough, there’s a chance that one (or more) of those things might happen. But in actuality, getting out to the range is still worth it — especially if you’re there with good friends. Thanks Kirsten for the reminder.
Today, October 27th, is the birthday of President Theodore (“Teddy”) Roosevelt. An avid explorer, hunter, and firearms enthusiast, Teddy Roosevelt (TR) was a larger-than-life figure who lead this nation as it emerged as a world power.
Theodore Roosevelt — A Great Leader
If you want to learn more about TR, we strongly recommend Theodore Roosevelt on Leadership, a book by noted author and political analyst James Strock. This work captures the vision, commitment, and personal courage that marked Theodore Roosevelt’s career. Theodore Roosevelt was a leader of uncommon strength who, through the sheer force of his extraordinary will, turned America into a modern world power. Thrown headfirst into the presidency by the assassination of his predecessor, he led with courage, character, and vision in the face of overwhelming challenges, whether busting corporate trusts or building the Panama Canal. Roosevelt has been a hero to millions of Americans for over a century.
Effects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 2 by Bryan Litz forBerger Bullets. Part One of this series focused on the importance of COAL in terms of SAAMI standards, magazine lengths, seating depths, and pressure levels. Another measure of length for loaded ammunition is highly important to precision, namely Cartridge Base to Bullet Ogive Length (CBTO).
Figure 2. Chamber throat geometry showing the bullet jump to the rifling or lands.
Look at Figure 2. Suppose the bullet was seated out of the case to the point where the base of the bullet’s nose (ogive) just contacted the beginning of the riflings (the lands) when the bolt was closed. This bullet seating configuration is referred to as touching the lands, or touching the riflings and is a very important measurement to understand for precision hand-loading. Due to the complex dynamics of internal ballistics which happen in the blink of an eye, the distance a bullet moves out of the case before it engages the riflings is highly critical to precision potential. Therefore, in order to systematically optimize the precision of his handloads, it’s critically important that the precision hand-loader understands how to alter bullet seating depth in relation to the barrel rifling. Part of the required knowledge is understanding how to accurately and repeatably measure the Cartridge Base To Ogive (CBTO) dimension. This is explained in the FULL ARTICLE.
Bryan Litz offers an extended discussion on how to measure CBTO using different tools and methods, including the Hornady OAL gauge. You can read this discussion in the full article found on the Berger Bullets website. CLICK HERE to Read Full Article.
Why Not Use CBTO as a SAAMI Standard?
If CBTO is so important to rifle accuracy, you might ask, “Why is it not listed as the SAAMI spec standard in addition to COAL?” There is one primary reason why it is not listed in the standard. This is the lack of uniformity in bullet nose shapes and measuring devices used to determine CBTO.
Figure 4. Two different bullet shapes, seated to the same CBTO length, but different COAL. Note the shiny scratches on the bullets made by the comparator tool which indicates a point on the bullet ogive near where the ogive will engage the riflings.
Benefits of Having a Uniform CBTO
There is another aspect to knowing your CBTO when checking your COAL as it pertains to performance. With good bullets, tooling, and carefully-prepared cases you can easily achieve a CBTO that varies less than +/- .001″ but your COAL can vary as much as .025″ extreme spread (or more with other brands). This is not necessarily bad and it is much better than the other way around. If you have a CBTO dimension that varies but your COAL dimension is tight (within +/- .002″) then it is most likely that your bullet is bottoming out inside the seater cone on the bullet tip. This is very bad and is to be avoided. It is normal for bullets to have precisely the same nose shape and it is also normal for these same bullets to have nose lengths that can vary as much as .025″.
Summary of Cartridge Base To Ogive (CBTO) Discussion
Here are four important considerations regarding bullet seating depth as it relates to CBTO:
1. CBTO is a critical measurement to understand for handloaders because it’s directly related to precision potential, and you control it by simply setting bullet seating depth.
2. Tools and methods for measuring CBTO vary. Most of the measurement techniques have pitfalls (which may give rise to inconsistent results) that you should understand before starting out.
3. A CBTO that produces the best precision in your rifle may not produce the best precision in someone else’s rifle. Even if you have the same rifle, same bullets, same model of comparator gauges, etc. It’s possible that the gauges are not actually the same, and measurements from one don’t translate to the same dimension for another.
4. Once you find the CBTO that produces the best precision in your rifle, it’s important to allow minimal variation in that dimension when producing quality handloads. This is achieved by using quality bullets, tooling, and properly preparing case mouths and necks for consistent seating.
