The NRA Black Powder Target Rifle Championship will be held October 1-7, 2018 at the Whittington Center in Raton, NM. During the week-long event, top Black Powder Cartridge Rifle (BPCR) shooters from around the country will test their skills at Raton with targets at 200 to 1000 yards. The event starts with mid-range matches at 200 to 600 yards, followed by 800- and 1000-yard long-range competition. On the firing line you’ll see many handsome, custom-built BPCRs (Sharps, Ballards, Browning High Walls, Rolling Blocks) with exquisite wood, hand-checkering, and color-case-hardened receivers.
The 800-1000 yard Creedmoor matches will be held Friday and Saturday, October 5-6. Interestingly, for safety reasons, there are minimum bullet weight and muzzle velocity requirements for the Creedmoor matches. These BPCR shooters launch some seriously heavy projectiles downrange.
REGISTRATION: Registration will take place at the Eagle’s Nest Building at the Whittington Center. NOTE: There are minimum requirements for bullet weight and velocity. Only ammunition which produces these results, or better, and only rifles that have long-range sights, will be permitted for use in the Creedmoor Championships. See the BPTR Nationals Ballistic Velocity Chart below for minimum requirements. There may be a 2% variance on bullet weight or velocity:
ACCOMMODATIONS: There are many motels in the town of Raton, about 10 miles from the Range. In additions, there are accommodations on the grounds of the Whittington Center: 90 beds in Competitors Housing and 100 beds in Log Cabins. These facilities fill up quickly — call the Whittington Center right away at (575) 445-3615 to reserve.

In discussions of ballistics, you’ll see references to “tangent”, “secant”, and “hybrid” 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, secant, and hybrid ogive bullet designs, to help you understand the characteristics of these three basic 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.”
Bryan Litz Explains Hybrid Design and Optimal Hybrid Seating Depths
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.
Report by Boyd Allen, IBS Vice President Photos by Hillary Martinez
Many of the nation’s best Score Benchrest shooters came to Maryland last month for the IBS 200/300-Yard Score Nationals. This is a one-shot-per-bullseye discipline dominated by accurate 30-caliber cartridges such as the 30 BR. Over the weekend of the 4th and 5th of August, 42 shooters participated in the 2018 IBS 200/300-Yard Score Nationals, held at the Thurmont Conservaton & Sportsman’s Club, in Thurmont, Maryland. Forty-one competitors shot Varmint for Score (VFS). Between the two 6X disciplines there were six competitors, equally divided between Hunter (H) and Varmint Hunter (VH). Dewey Hancock was “Top Gun” for the match, winning the VFS 200/300 Grand Agg with 500-23X, a possible new record.
There are six bullseyes on an IBS Score target. Competitors take one shot per bull for five scored shots. The sixth (bottom right) bullseye is reserved for sighter shots.
Rising River After Rain
This match had some unique challenges — caused by a river that overflowed after a rain. Thankfully, the match proceeded without major problems once needed equipment was moved. It rained nearly half an inch the Friday night before the match, as it had for several days. Given the flooding, there was a slight delay Saturday morning. The scoring trailer had to be moved because it been parked (before the rain) in a low area adjacent to where Big Hunter Creek empties into the Monocacy River. (In the satellite view, the firing line cover is in the middle, about one-third up from the bottom.)
Hot and Humid in Maryland — The match director described the weather as very hot and humid. On Saturday, the temperature varied from 66 to 81 degrees, the humidity from 62 to 100 %, and the wind speed from 0 to 9 mph. On Sunday, things warmed up a bit, the humidity was reported as a little lower, as was the wind speed.
The Green Fields of Thurmont — With recent rains at Thurmont, lush green grass stretched from firing line to targets. This elicits envy from a shooter who has spent all of his time on ranges that do not have a single blade of green anywhere, except for a few weeks during a short rainy season. To my eyes, this range is beautiful.
Thurmont shooters are blessed with a truly outstanding facility that serves all types of shooting. There are fifteen covered benches of mixed construction under a sturdy cover, with plenty of parking both for vehicles and RVs. Learn more about the Thurmont Club at TCandSC.org.
TOP TEN Match Results, and Equipment List
Can anyone identify that big gold-tone coaxial rest on the right?
The VFS Grand Aggregate Top Five were: Dewey Hancock (1st Place), John Bosley (2nd), Ronnie Milford (3rd), Brian Fitch (4th), and Jim Cline (5th). VFS winner Dewey Hancock shot a possible new 200/300 yard record with a 500-23X.

Wayne France — with the “I just won a Nightforce” smile!
Steve Eller smiling — BIB Bullets from Randy Robinette are always a good choice.
Dean Breeden, Match Director and Competitor
Match directors do not get the appreciation they deserve. The match calendar would be blank without them. Score Nationals Match director Dean Breeden ran a great show here. In addition to rescuing a trailer from flood waters, and running the 200/300 Score Nationals, Dean also himself competed at the Nationals, shooting two rifles. He did well, with Top Ten finishes at both distances, in both VFS and Hunter classes (3rd in Hunter at 300 yards).
While Dean may be under-appreciated as a match director, Dean is widely recognized as one of the best IBS score shooters out there. Dean holds six (6) current IBS Score Shooting records.
In his Match Report, Dean acknowledged and thanked the generous match sponsors:

Posting on Facebook, Michael W. said: “Maybe it’s just me but I LOVE coming home to packages from the UPS driver sitting on my deck! Now I can get serious about creating some Match Grade ammunition!” Michael showed off some very impressive reloading hardware, including a 21st Century Shooting “Mini-Lathe” Neck-Turning system, 21st Century Concentricity Gauge, Shars Tube Micrometer, and the A&D FZ-120i Precision Balance. Cool Tools indeed!
21st Century Neck-Turning Lathe — A Gem
The 21st Century Neck-Turning Lathe works great — this is what we use to turn necks. It floats at both ends, so it runs very smoothly. You can use it manually or with power. It gives you very precise, clean cuts with a minimum of case lube. The cutting tool is hard and sharp so you can do large quantities of brass without having to adjust the cutter position for wear. We’ve used a half-dozen neck turners and this 21st Century Unit is our favorite.
21st Century Concentricity Gauge — Smart, Efficient Design
The beautifully-crafted 21st Century Concentricity Gauge is fast and easy to use yet very precise. The twin, roller-equipped case supports slide back and forth on rails so you can measure any size case, from a 17 Fireball up to a 50 BMG. The horizontal dial indicator also slides on parallel rails so you can easily measure any spot on a case or loaded round — from bullet tip (or case mouth on empty case) down to the mid-body. We like to measure run-out on our sized, empty brass on the necks and then measure again on the bullet ogive with loaded rounds. The large-diameter wheel allows bump-free, “no wobble” case rotation, delivering better results than spinning cases with your fingers.
Concentricity gauge uses stainless turning rollers for less friction and more consistent read-outs.
A&D Precision Balance — Ultra-Precise with No Drift
The A&D FX and FZ-series scales are magnetic force restoration balances with 0.001 gram sensitivity so they are accurate to the kernel. This balance will not drift like less advanced, load cell-based digital scales. The scale’s high sensitivity and extreme stability allow you to weigh charges and sort brass, primers, and bullets with much higher precision.
What Gadget Would YOU Like To Have Delivered?
Here’s a question for our readers… What are YOUR favorite reloading tools on currently on your bench? And if you could have the UPS driver deliver a new tool tomorrow, what would you like him to bring? A 21st Century Hydro Bullet Seater (awesome Arbor Press)? Maybe a Whidden Micro-Adjustable Sizing Die? How about the amazing Auto Trickler and Auto-Throw system from Canada? That combines a A&D FX/FZ scale with a powder thrower and microprocessor-controlled trickler. With the push of a button you get a charge dispensed and weighed to single-kernel accuracy.

This rifle features Browning’s patent pending 10-round rotary Double Helix™ magazine. Browning says “No magazine is easier to load and more reliable” than the new Double Helix. This rifle originally sold for $839.99. Now, you can get one for $499.99 after $100 Browning Rebate. This same rifle is also available in .22 LR and .22 WMR for the same price. REBATE INFO.
2. Grizzly.com — Bald Eagle Rests $165.00 – $199.95
Bald Eagle (by Grizzly) offers one of the best value-priced front rests on the market. We’ve seen F-Class shooters win matches with the Bald Eagle Slingshot Windage Rest, which costs less than a fifth of a premium co-axial rest. For a new shooter, this is a very cost-effective solution. One Forum member purchased this Bald Eagle BE1006 rest for his grandson, deciding it was the best rest under $300.00. Both rests shown offer a cable (with large knob) for easy windage adjustment. The Slingshot model, in cast iron or aluminum, has an elongated front leg for added stability. This also brings the Windage knob within easy reach. The aluminum version (BE1005) is considerably lighter and $35 cheaper, so it may be preferred by rimfire and varmint shooters. Note: Front sandbag sold separately.
Bushnell’s highly-regarded Elite 4500 Series scopes offer very good performance and reliability for the price. Here’s a great deal on a Bushnell 6-24x40mm Elite 4500 with Multi-X Reticle, 1/4-MOA clicks, and 1″-diameter main tube. Right now this fine optic is just $359.99 — nearly $240 off the regular price.

Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion.
This remarkable 15-shot sequence was shot by French benchrester Pascal Fischbach using his 6 PPC fitted with a CG (Carlito Gonzales) action and a Bukys barrel tuner.
Pascal reports: “After [bullet] seating and load validation, I put the Bukys tuner on, screwing it out 10 turns. According to Carlito, the CG’s super stiff action-to-barrel fit gives a faster vibration modulus that is detrimental below 10 turns [position of the tuner].” Pascal’s procedure was to screw out the tuner 1/4 turn progressively from one shot to the next. He shot one bullet at each tuner position, with a total of 15 shots.
Left Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Right Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Pascal observed: “Note the point of impact displacement [from shot to shot] tracks clearly along a sinusoide (sine wave curve).” This is indeed notable and significant! This shows how the tuner’s ability to change barrel harmonics can alter the position of the muzzle as each bullet exits, resulting in a higher or lower POI. Pascal sent his results to Carlito Gonzales in Argentina for analysis.
Pascal poses this question to readers: “Guess which three positions Carlito recommends to try?”
Editor’s Note: While this target sequence clearly shows how tuner position can alter bullet point of impact, this, by itself, does not tell us which tuner position(s) are best for accuracy. That will require further multi-shot group testing, involving careful experimentation with tuner position (and powder charge weights). But for those folks who doubt that a tuner can make a difference on a short, fat barrel, just take another look at the photos. The up/down changes are undeniable, and noteworthy in the wave pattern they follow.
Shooting Set-up and Test Conditions:
Pascal did this test at an outdoor range under very good conditions: “This was shot at my home range, outdoors, with four Smiley flag. The range is a narrow cut in high woods. Wind was consistent with readable flags. I started testing the tuner from 10 turns out and on to 15. I recently… found a sweet spot very close to the rearmost position of the tuner, so the rigidity provided by this super long tenon (just short of 70mm) was not a reason to overlook the recommended Bukys tuning procedure.”
We know that Competition Machine (Gary Eliseo) makes great chassis systems and Pierce Engineering (John Pierce) makes great actions. But sometimes a project comes together even better than one can imagine. The folks at Pierce Engineering recently completed an Eliseo Tubegun that displayed some mind-blowing accuracy during initial testing. This was a special rifle built to a client’s spec in .22 PPC.
After his team completed the rifle, John Pierce took the Tubegun to the range to make sure everything was working right. The rifle was chambered for the .22 PPC, a known accuracy cartridge. Would this cartridge shoot in this gun? Heck yeah was the answer! The first two shots out of the gun were touching. That was promising enough. But then John drilled a five-shot group that was basically one hole! Here is that target. First two shots upper left, then the five-shot group below and to the right. Chassis-maker Gary Eliseo commented: “that’ll do just fine…”
Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
And if the owner ever wants to show off a “wallet group” for his new rifle — well he’s got that, thanks to John’s great trigger-pulling and rifle-building. Using On-Target software we measured that five-shot group at 0.189″ (see photo at right). That’s crazy small for a new gun with zero load development. That’s also a testimony to the quality of the Norma .22 PPC brass.
Why the .22 PPC Chambering?
The customer owns other Eliseo Tubeguns, but wanted something that combined extreme accuracy with very low recoil. He also wanted to be able to shoot factory brass without fire-forming. Norma makes very high-quality .22 PPC cartridge brass that is an easy load and shoot solution. In fact the folks at Pierce Engineering custom-loaded a quantity of .22 PPC ammo for this Tubegun and shipped it off to the customer along with the new rifle. NOTE: Loading ammo is not something that Pierce normally does, but this was a special client request.
Here is an article Glen Zediker wrote for the Midsouth Blog. In this article Glen gives important advice on selecting, handling, seating, and testing primers. The right primer choice can and will affect your load’s performance and accuracy. And proper primer handling is essential for safety.
by Glen Zediker
The primer is one component in the collection that might not get all the attention it warrants. That’s because it is the one thing, above all other components, that you don’t want to just swap and switch around. We’ve all heard cautions about testing new lots of every component, especially propellant, but primers not only change lot to lot, they vary greatly in their influence on any one load, brand to brand.
The difference in one brand to the next can equal a good deal more or less pressure, for instance. While there are “general” tendencies respecting the “power” of various-brand primers, always (always) reduce the load (propellant quantity) when switching primers.
This has become more of an issue over the past few years as we’ve faced component shortages. I can tell you without a doubt that going from a WW to a CCI, or from a Remington to a Federal, can have a major influence on a load. I establish that from chronograph readings. No doubt, it’s best to have a good supply of one primer brand and lot that produces good results, and when that’s not possible, it’s a hard sell to convince someone to stop loading ammo and get back to testing. But. It is important. I can tell you that from (bad) experience. How I, and we all, learn most things…
When I switch primers, whether as a test or a necessity, I reduce my load ONE FULL GRAIN. There can be that much effect.
The Elements of a Primer
A primer is made up of a brass cup filled with explosive compound (lead styphate). Lead styphate detonates on impact. Primers don’t burn – they explode! In the manufacturing process, this compound starts as a liquid. After it’s laid into the cup, and while it’s still wet, a triangular piece or metal (the “anvil”) is set in. When the cup surface is struck by the firing pin, the center collapses, squeezing the explosive compound between the interior of the cup and the anvil. That ignites the compound and sends a flame through the case flash hole, which in turn lights up the propellant.
Primers Can be Dangerous — Particularly When Stacked
Don’t underestimate that. I’ve had one experience that fortunately only created a huge start, but I know others who have had bigger more startling mishaps. These (almost always) come from primer reservoirs, such fill-tubes. Pay close attention when charging up a tube and make sure all the primers are facing the right way, and that you’re not trying to put in “one more” when it’s full! That’s when “it” usually happens. What will happen, by the way, is akin to a small grenade. Static electricity has also been blamed, so keep that in mind.
Sizes and Types of Primers
Primers come in two sizes and four types. “Large” and “small”: for example, .223 Rem. takes small, .308 Win. takes large. Then there are pistol and rifle in each size.
Rifle primers and pistol primers are not the same, even though they share common diameters! Rifle primers [normally] have a tougher cup, and, usually, a hotter flash. Never swap rifle for pistol. Now, some practical-style competitive pistol shooters using their very high-pressure loads (like .38 Super Comp) sometimes substitute rifle primers because they’ll “handle” more pressure, but they’ve also tricked up striker power. That’s a specialized need.
Further, some primer brands are available with a “magnum” option. Some aren’t. My experience has been that depends on the “level” of their standard primer. A magnum primer, as you might guess, has a more intense, stouter flash that travels more “deeply” to ignite the larger and more dense powder column. It reaches further, faster.
Flash Consistency Counts Flash Consistency is very important, shot to shot. The consistency of every component is important: bullet weights, diameters, case wall thicknesses, and all the way down the list. We’re hoping to get more consistent behavior from a “match” or “benchrest” primer, and we’re paying more for it. I can tell you that some brands that aren’t touted as “match” are already consistent. That all comes from experience: try different primers, just respect the need to initially reduce the load for each test. I can also tell you that my notes tell me that the primer has a whopping lot to do with how high or low my velocity deviations plot out.
Primer Dimensional Differences and Primer Tools
One last thing — there are small variations in primer dimensions (heights, diameters) among various brands. These variations are not influential to performance. However — small diameter variations can influence feeding through priming tools. This can be a hitch especially in some progressive loading machines. Manufacturers usually offer insight (aka: “warnings”) as to which are or aren’t compatible, so find out.

We first featured this story in 2010, but the results of this rimfire ammo test have been of such widespread interest that we try to bring the test to readers’ attention every year.
In 2010, the staff of AccurateReloading.com Forum completed a massive .22LR Rimfire Ammunition Testing Project. Some 55 different types of ammo were tested, using a highly-accurate Swiss-made Bleiker rifle, with a 2-stage trigger. All ammo varieties were tested at 50 yards, 75 yards, and 100 yards, shooting five, 5-shot groups at each distance. Though these tests were completed some time ago, many readers have requested a “reprint” of the ammo rankings, so we’ve republished this data below.
The results are fascinating to say the least (and perhaps eye-opening). The tester observed: “I got some amazing groups, and some which are, frankly, absurdly bad! This has re-enforced what I had experienced with 22 ammo in the past — that is being consistently inconsistent.”
While we strongly caution that .22LR rimfire ammo may work well in one gun and not another, and ammo performance can be improved through the use of barrel tuners, the AccurateReloading.com research provides invaluable guidance for smallbore shooters. Overall, the testers burned through over 4,000 rounds of ammo, and you can see the actual test targets online. To read all the test reports, and view target photos visit AccurateReloading.com.

Hybrid Bullet Design — Best of Both Worlds?
The VFS Grand Aggregate Top Five were: Dewey Hancock (1st Place), John Bosley (2nd), Ronnie Milford (3rd), Brian Fitch (4th), and Jim Cline (5th). VFS winner Dewey Hancock shot a possible new 200/300 yard record with a 500-23X.
A&D Precision Balance — Ultra-Precise with No Drift
Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion. 
Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
