At SHOT Show 2019, some of the most impressive new products were in the realm of scopes and electro-optics. We are seeing big companies like Leica, SIG Sauer, Swarovski, and Zeiss moving big-time into the technological marriage of microchips and lenses. With the release of the $4500 Swaro dS, a scope with no manual windage or elevation controls, we are really entering a new era in aiming systems for shooters.
Swarovski dS Rangefinder Scope with Ballistics “Brain”
Swarovski rolled out a new flagship scope this year at SHOT Show, the remarkable dS 5-25×52 P. This $4500+ wonder features a built-in laser rangefinder (like the Burris Eliminator). But there’s more — working with a smartphone App, the dS incorporates a sophisticated ballistics computer that calculates your trajectory at any distance and then displays an aim point on your reticle. It even adjusts the aim point for the wind (with data entered wirelessly via mobile device).
This really is a state-of-the-art electro-optical system. However, there are some negatives to consider. First there are no conventional elevation or windage knobs/turrets. So, if your battery dies in the field, you are SOL. (FYI that big “turret” in the middle is actually just a battery and tool holder). Secondly, all that smart calculation depends on extremely accurate BC and velocity data. If you switch ammo, and don’t have an accurate velocity or BC, you won’t get the right solution and there are no knobs to turn to fix that. The dS will give you an aim point, but it might not match your true ballistics. (NOTE: There are hidden mechanical controls for setting your zero, but these are not intended for conventional shot to shot adjustments).
High-Magnification Competition Scopes
Kahles K1050 — Central Parallax, Great Glass
Kahles scopes are now being used by many of the top shooters in PRS game. Kahles optics offer great European glass, precise controls, and some unique features. Our readers may not realize that Kahles makes an outstanding high-magnification zoom scope suitable for long-range benchrest and F-Class comptition, the Kahles K1050. This 10-50x56mm optic has a unique centrally mounted parallax control — great for lefties or guys who run a left port/right eject. The Kahles K1050 has a true 8 meters to infinity parallax adjustment range making it suitable for everything from Field Target air gun, 1000-yard competition, and long range tactical. The Kahles K1050 costs $2899.00 — that’s midway between a Vortex Golden Eagle and a 10-60x56mm March High Master (starting at $3425.00).
Sightron SIII 10-50x60mm
Sightron offers a very affordable 10-50x60mm scope in its SIII optics line. There is a special version for Field Target competition that comes with a “Big Wheel” parallax control. Field Target competitors use the Parallax control to determine target range.
ELR Scope — For 2 Miles and Beyond
March 6-60X Genesis with 400 MOA elevation
A typical premium riflescope might have 50-60 MOA of elevation. That’s enough for shooting out to 1500 yards or so with a high-BC bullet launched at 2900 fps. But for Extreme Long Range (ELR) shooting you need more elevation adjustment, and that’s where the innovative March 6-60X Genesis optic stands out. This unique optic offers a whopping 400 MOA of elevation adjustment. That ample elevation doesn’t come cheap however — the 6-60x56mm Genesis sells for $6950.00. CLICK HERE for full specifications.
Lightweight Hunting Scopes
As scopes have grown increasingly sophisticated and complex, they have also become bulkier and HEAVIER. That’s a big deal for a hunter who may be carrying a rifle, plus another 20-30 pounds of gear and food/water. The average dear hunter will be taking a shot well inside 400 yards so he doesn’t need 25X power or fancy features. He does need clarity, good low-light performance, and reliability — and LOW WEIGHT. We think a good deer hunting scope should come in under 1.5 pounds (without rings). Here are two smart hunting optics, both under 20 ounces.
Leupold VX Freedom — 12.2 ounce Weight, Simple, Affordable
The Leupold VX-Freedom 3-9x40mm weighs just 12.2 ounces and street price is under $200. It has a 4.7mm exit pupil, 60 MOA of elevation, and a 33.7 ft Field of View at 100 yards.
Zeiss 3-12x44mm Conquest — 18.2 ounce Weight, 90% Light transmission, 4X Zoom
These riflescopes were designed as a lightweight, high-performance product line for demanding hunting and shooting applications. The Zeiss 3-12x44mm Conquest delivers 90% to-the-eye light transmission, along with 70 MOA of both elevation and windage travel. This premium second focal plane scope weighs just 18.2 ounces, slightly over one pound.
Compact Spotting Scopes for Field Carry
Many shooters and hunters don’t want or need a heavy, bulky spotting scope. They need a spotter to see mirage, and to deliver more magnification than can be comfortably handheld with binoculars. For hunters, weight and overall size are key. The hunter wants a spotting scope that can be packed and carried easily. Here are two clear, sharp spotter options in a smaller format. The Leupold Gold Ring 15-30x50mm Compact Spotter is particularly well-suited to hunters and tactical shooters.
Nikon Monarch Fieldscope 60ED-A
Small but powerful — that describes the Nikon 60ED-A Monarch Fieldscope with 16-48X eyepiece. This unit delivers big spotter performance in a much smaller package. It focuses fast and showed very good sharpness though we observed the image darkens at higher magnifications. This has ED glass and Nikon’s proprietary “field flattener” lens system that enhances sharpness throughout the entire field of view.
Leupold 15-30x50mm Gold Ring Compact Spotting Scope
The affordable Leupold Gold Ring Compact Spotter offers 15-30X magnification. That’s plenty for spotting game or viewing mirage. This unit is remarkably compact and we like the simple right-side focus knob. Half the size of typical spotting scopes, this Compact Leupold spotter weighs just 21.5 ounces (1.34 pounds).
Superb Binoculars — When Cost is No Object
Leica Noctivid 8x42mm Binoculars
Our Hunting Editor Colton Reid is a Ph.D. who works with specialized electro-optical devices costing over $30,000. So he knows a few things about light waves and glass quality. When he looked through the 8×42 Leica Noctivid his comment was simple but telling: “These are the best compact binoculars I’ve ever looked through. The clarity and brightness are truly exceptional”. At nearly $2700.00, Noctivids are crazy expensive, but the quality will be worth it to some buyers.
Parting Shot — Think about the Warranty BEFORE You Buy
This patched-up Razor spotting scope was on display at the Vortex booth. We actually know the history of this particular spotter — it belonged to one of our Forum members. He sent this busted unit back to Vortex, and Vortex sent him a brand new Razor spotter. That Forum member told us: “Vortex earned a customer for life when they replaced my spotter, no questions asked. When Vortex says its warranty is ‘Unlimited, Unconditional, Lifetime’, believe it.”
Here’s a “must-read” article for .22 LR rimfire shooters. The recently-released October 2018 issue of Shooting Sports USA (SSUSA) includes a great article with data on thirty-one (31) different types of popular .22 LR rimfire ammunition. The line-up includes low-speed, standard, and Hi-Velocity types, plus choices for plinking, varminting, and target applications. Brands tested include: Aguila, American Eagle, CCI, Federal, Fiocchi, Lapua, Remington, and Winchester. The slowest ammo, CCI Quiet-22 Lead RN, clocked 727 FPS. The fastest ammo, CCI Short-Range Green Lead-Free HP, ran 1735 FPS, more than twice as fast as the Quiet-22.
For each ammo type, SSUSA lists the bullet weight, velocity (FPS), and average of two, 5-shot groups at fifty yards. The most accurate ammo was Lapua Center-X LRN, with a 0.37″ average 50-yard group size. Second best was Lapua X-ACT LRN at 0.42″. Ammo was tested from a bench with a Cooper Model 57-M rifle fitted with 3-9x33mm Leupold VX-2 scope. The ammo offerings were grouped into three categories: (1) Varmints/Small Game; (2) Target; and (3) Plinking. (See ammo tables below.)
Click for larger page-view.
Different types of .22 LR (Long Rifle) rimfire ammo have different applications. Subsonic ammo, typically, is best for 25m to 50m target work with precision rimfire rigs. Hi-Velocity .22 LR ammo provides a flatter trajectory for longer ranges. SSUSA explains: “The array of .22 LR loads… turns a person’s head every which way. Subsonic target loads are the key to decisive accuracy on targets, while hyper-velocity cartridges provide striking bullet expansion on small varmints. In between, standard and high-velocity .22 LRs are loadrf with a variety of bullet weights and styles for everything from small-game hunting to plinking[.]” READ Full SSUSA .22 LR Rimfire Ammo Story.
CMP Competition Rulebooks that will govern all CMP sponsored and sanctioned competitions in 2019 have now been approved by the CMP Board’s Rules Committee and posted on the CMP website. Significant changes in this year’s rulebooks include dividing the former Service Rifle and Pistol Rulebook into two separate rulebooks, the establishment of a new program to give persons with disabilities an opportunity to earn Distinguished Badges, and the creation of separate unlimited classes for Modern Military Rifles and Rimfire Sporter Rifles. 2019 CMP Competition Rulebooks are effective immediately and can be downloaded from the CMP website by using the following links:
CMP Games Competition Rules, governs As-Issued Military Rifle, Modern Military Rifle, Vintage Sniper Rifle Team Match, Rimfire Sporter Rifle and As-Issued Pistol
LINK: http://thecmp.org/wp-content/uploads/CMPGamesRules.pdf
Here are key 2019 CMP Rule Change Highlights. For a more complete list of important changes, read the official CMP 2019 Rule Change Summary.
New Distinguished Marksman Program For Shooters with Disabilities
A major new CMP program being introduced in 2019 is the Distinguished Marksman Badge Program for competitors with medical or physical limitations or disabilities. To implement this program, the CMP is establishing a new Distinguished Badge called the Distinguished Marksman Badge. Any rifle or pistol competitor with a disability or limitation that previously prevented them from fully meeting rules requirements for earning EIC credit points is invited to apply to the CMP for a “Distinguished Marksman Authorization” (contact acantu@thecmp.org or phone 419-635-2141, ext. 602).
Electronic Scoring Target Rules
New electronic target (EST) installations at the Talladega Marksmanship Park and CMP Travel Games necessitated special rules to govern irregular shot entries that may appear on electronic targets. CMP EST rules were updated this year, based on EST experiences. CMP Rules now define EST complaint resolution processes for: 1) a protested shot value; 2) a missing slow-fire shot; 3) a missing rapid-fire shot; 4) an extra slow-fire shot and 5) an extra rapid-fire shot.
Highpower Rifle Rule Changes
Separate Highpower Rifle Rulebook
Until this year Service Rifle and Pistol events all had the same rulebook. As a result, rules frequently skipped from rifle to pistol and back and this often caused confusion. Now there are two separate rulebooks, one for Highpower Rifle and a separate rulebook for Pistol.
Long Range Rifle Classification System
The CMP brought Long Range Rifle competitions at 800, 900 and 1000 years back to Camp Perry and the National Matches in 2018. This successful new program attracted 182 competitors who made 454 event entries. This year’s change features the introduction of a Long Range Rifle classification system that will expand the CMP Highpower Rifle classification system implemented in 2018 (HP Rule 3.11.4).
National Matches Program
The 2018 National Matches Program that introduced CMP Cup Matches, Long Range Rifle Matches and the Roosevelt Match (for U.S. Krag and M1903 rifles) will be unchanged in 2019. All of the highpower rifle events that were on the 2018 National Matches Program are already in this year’s National Matches Schedule. If you have not done so already, download the 2019 National Matches Calendar.
In 2019, the “Standard Modern Military Rifle” will return to its original rules for AR-type rifles that featured a 7.5 lbs maximum weight and metallic sights only. In 2019, AR-type rifles that weigh more than 7.5 lbs or that have optical sights will compete in a separate Unlimited Class. In addition, Modern Military Rifles with optical sights will now all be in the Unlimited Modern Military Rifle Class. Free-floating handguards will be allowed in both the Unlimited and Standard Modern Military Rifle Classes.
CMP Games Rule Changes
The CMP Games Rulebook that governs As-Issued Military Rifle and Pistol events as well as Rimfire Sporter Matches has some of the most significant 2019 rule changes. These include the establishment of an Unlimited Modern Military Rifle Class and the expansion of the Rimfire Sporter Tactical Class to become a combined Tactical and Unlimited Class (TU-Class). Changes in this rulebook are.
Modern Military Rifle
For 2019, after much debate and inputs from many, the CMP decided to return the first Modern Military Rifle Class to its original rules as a Standard Modern Military Rifle and to establish a separate Unlimited Modern Military Rifle Class. The Standard Modern Military Rifle will go back to its original 7.5 lbs. weight limit for AR-type rifles and 9.0 lbs. for M1As. Standard Modern Military Rifles will be restricted to metallic sights only. Rifles that weigh more than 7.5 lbs. or 9.0 lbs. or that have optical sights will now be in the Unlimited Modern Military Rifle Class. Restrictions against float tubes or metallic sights with finer adjustments were removed for both classes.
As-Issued Military Rifle Events
The core of the CMP As-Issued Military Rifle program is the ever-popular Garand-Springfield-Vintage Military Rifle triad. Those events and the Carbine Match, which accompanies them on many match programs, remain unchanged.
The digital archives of Shooting Sports USA magazine (SSUSA) features an Expert Forum on Wind Reading. This outstanding article on wind reading starts off with a section by ballistics guru Bryan Litz, author of Applied Ballistics for Long-Range Shooting. Then four of the greatest American shooters in history share their personal wind wisdom. Lanny Basham (Olympic Gold Medalist, author, Winning in the Wind), Nancy Tompkins (Past National HP Champion, author, Prone and Long-Range Rifle Shooting), David Tubb (11-Time Camp Perry National Champion), and Lones Wigger (Olympic Hall of Fame) all offer practical wind-reading lessons learned during their shooting careers.
Whether you shoot paper at Perry or prairie dogs in the Dakotas, this is a certified “must-read” resource on reading the wind. Here is a sample selection from the article:

A customer of well-known gunsmith (and Hall-of-Fame shooter) Thomas “Speedy” Gonzalez recently asked Speedy about bedding compounds. Speedy offered some interesting advice based on long-term testing of various materials. Speedy favors Marine-Tex because it is very stable over time, while other materials can shrink up to 6% dimensionally. A good bedding job should be a perfect fit to your barreled action. If the bedding material shrinks over time, that is NOT a good thing….
Speedy’s customer asked: “I know you’re not a Devcon man in regards to bedding compounds but I respect your input in such matters and my question is this in regard to aluminum actions. If Devcon was considered, for an aluminum action, would you prefer aluminum compound formula or steel formula? I personally prefer Devcon steel and Marine-Tex for steel receivers but my experience with aluminum is limited. Also do you have a release agent preference that works better with aluminum?”
Speedy answered: “My only preference of one epoxy over another is their stability over time. My buddy who works for the Texas State Weights and Measures Department had me cast several of the most common types of epoxies used for bedding into 1.000″ machined blocks. After one year of being kept in a controlled climate and measured for shrinkage monthly, the Marine Tex shrunk only 1/10th of 1% (i.e. 0.1%) whereas almost all the others (including Devcon Steel formula, Devcon Aluminum formula…) shrunk 3% to 6%. The only other compounds that matched the Marine Tex were Araldite 1253 and Araldite 2014, with the latter being quite expensive for daily use.”
Speedy added: “The Marine Tex Grey has no atomized metal in its makeup even though it appears that it does. This can be proven by the use of a strong neodymium magnet. What is humorous to me is that people don’t like aluminum yet will bed their actions atop aluminum pillars that have twice the coefficient of expansion (COE) of steel. Like Devcon, it is what people have always done and used. Thus [they] perpetuate the same old stuff. That’s my two cents’ worth. But as I tell everyone, ‘I’ll tell you what I know or do, but it’s not my job to convince anyone to do it my way’.”
Release Agents — Try Shoe Polish
Regarding release agents, Speedy stated: “I use Kiwi Neutral or Tan shoe polish. This works great and you can find it anywhere. Do NOT use the black or brown as it will stick.”
View More Photos of Speedy Inletting and Bedding Job CLICK HERE to see an interesting bedding job done by Speedy using a custom titanium bedding block. Speedy notes, “The stock was a raw blank requiring full inletting for the action to fit properly plus the titanium block. All the loading ports, bolt handle cut, bolt stop, and trigger guard cuts were done with diamond tooling to eliminate fraying and/or delamination of the wood.” You’ll find more projects by Speedy on his Facebook Page. Speedy is in San Antonio, Texas now, and accepting new projects with his company S.G. Rifles LLC.
Hand-loaders have never had so many great choices in single-stage presses, with many different configurations and features. There are classic O-Frame presses, Coax-style presses, Open-front presses, Pyramid presses, and compact C-Frame presses. Here is our 2019 Single Stage Press Showcase with products from Forster, Frankford Arsenal, Hornady, Lee, Lyman, MEC, and RCBS. We’ve included short videos showing the features of these reloading presses.
If you are shopping for a new press you should look at the various features of each. You may prefer something classic like a Rock Chucker, or the innovative open-front MEC. If you are looking for a compact press to use at the range, the new Lyman C-Frame is very impressive for the price. And the Forster Co-Ax remains a great addition to any loading room.
MEC Marksman Single-Stage Press
If you are looking for a new, full-size single-stage reloading press, definitely consider the MEC Marksman. Created by the makers of the popular MEC shotshell reloading systems, the MEC Marksman combines a sturdy cast-iron frame with a modern open-front design. With a $189.99 street price the Marksman press cost roughly $20 more than an RCBS Rock Chucker, but the MEC offers some distinct advantages — such as an open front plus a floating shell-holder system.
Our friend Gavin Gear of UltimateReloader.com got his hands on a MEC Marksman press and put it through its paces. He came away impressed with the product, saying it delivers excellent performance, and has many impressive features. Gavin tells us: “Cast iron tools and machines are a lifetime investment. The made-in-USA MEC Marksman features ductile cast-iron construction, an open-front frame design for easy cartridge access, a new floating shell-holder design with a unique retention system, and ambidextrous handle setup.” MEC also offers a wide selection of accessories for the Marksman press, including a press riser/mount, shell-holder caddy, and die trays.
Frankford Arsenal M-Press Coaxial Reloading Press
Sorry, this new Frankford Arsenal coaxial M-Press has not started shipping yet so we don’t have a video. But MidwayUSA says it should arrive by mid-February 2019. We think this new M-Press should interest Forster Co-Ax fans. While the operation is similar to the Forster Co-Ax, there are some important differences. The new M-Press mounts on a flat surface, with nothing protruding below. That is significantly different than the Forster Co-Ax. The die block is different. It also appears that the shell-holder system is different. But this still self-aligns like a Forster Co-Ax. “A free-floating design allows the die and shellplate to move on two axis, so the case is always perfectly centered in the die, minimizing bullet runout.” The way the arms move is also different. In the Forster Co-Ax, the rods slide within the press frame and the part that holds the shell is fixed to them. In this design the rods are stationary and the part that holds the shell slides on them. However, the overhead handle certainly does copy the distinctive Forster design. NOTE: According to MidwayUSA, this M-Press does NOT have priming capability, unlike the Forster Co-Ax. Credit Boyd Allen for design analysis.
Forster Co-Ax Press
If you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video above, a very thorough video review by Rex Roach. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.
In recent years, Forster Co-Ax® presses have been somewhat hard to find, as demand has out-stripped supply. The Co-Ax has many dedicated fans, given its unique features, such as the floating case-holder jaws, and easy, rapid slide-in/slide-out die placement. We’ve also found that Co-Ax presses load very straight ammo and we like the ability to switch between short handle (good for bullet seating) and long handle (ideal for heavy case-sizing tasks). We also think the Forster Co-Ax has one of the best spent primer capture systems on the market — a straight drop into a removable plastic cup. Simple and it works.
Lyman Brass Smith Victory Single-Stage Press
Lyman’s New Victory Single-stage Press competes with the RCBS Rock Chucker Press. With beefy cast iron construction, the Victory’s strength and leverage rivals the Rock Chucker. If you like to prime on a press, this Victory has a priming system that’s much easier to use than the Rock Chucker system. The priming tube is right up front. Simply push the shuttle at the button of the tube to advance the primer into place. The entire primer-loading system can also be removed so it doesn’t interfere with case and bullet-handling operations. We generally prefer to prime cases separately using a dedicated hand- or bench-mounted tool, but the Victory press does the job nicely. Overall, the Victory is a great value in a full-size “O-Frame” press. It’s on sale now for $154.99 at Midsouth.
RCBS Rock Chucker Supreme Single-Stage Press
Nearly every serious hand-loader has owned or used the RCBS Rock Chucker press. This Editor still uses a Rock Chucker passed down by his brother 20 years ago. And yes, it is still going strong. The latest Rock Chucker Supreme single-stage press features an improved “upside-down Y-path” dual-bin spent primer catcher. Otherwise the Rock Chucker Supreme remains big, strong, versatile and sturdy. It has very strong linkages, with a compound leverage system providing plenty of power — FL-sizing is a breeze even with large, magnum cases. The 1″-diameter ram has 12.5 sq. inches of ram-bearing surface.
Some people may not know that the Rock Chucker offers a secondary 1 1/4″ x 12 thread for shotshell reloading dies and Piggyback 3 upgrade. The Rock Chucker Supreme retails for under $180.00 ($167.50 now at Bruno’s). The RCBS Rock Chucker is definitely a quality product that can last a lifetime. For heavy-duty sizing chores this remains one of the best choices in single-stage presses. We do recommend shopping around. You can sometimes get a pretty big discount on Rock Chuckers and RCBS has regular rebate programs.
Lyman Brass Smith Ideal C-Frame Compact Press
The Lyman Brass Smith Ideal Press is a very affordable, cast iron C-Frame reloading press. We think it is the new “class leader” in compact presses. This works great as a secondary press for your reloading room or a small press you can take to the range. The large front opening allows you to access the shell holder without hitting the support bar on other types of presses. Unlike other compact presses made from aluminum, Lyman’s Ideal press is cast iron so it is rigid and strong. The high-quality steel ram is one inch in diameter. The Brass Smith is a true ambidextrous press that can be accessed from either side and mounted the same. This is a great choice for a second, auxiliary press for depriming and bullet seating.
Hornady Iron Single Stage (Open-front) Press
In this “Reloading with Rosie” video, the attractive female host loads some ammo using the Hornady Iron Press. With a beefy, pyramid-style cast-iron frame with an open front, this press offers some advantages over a traditional “O-Frame” type press. Access is considerably easier, for one thing. And the top of the press includes slots to hold dies and tools — that’s really a very nice feature that saves time. Also an optional “automatic” priming system shuttles primers from a vertical tube in the back to the shell-holder in the front. That’s clever. Over all the Iron Press is a nice piece of engineering — good job Hornady.
Lee Classic Cast (Iron) Breech Lock Press
The Lee Classic Cast Breech Lock Press offers excellent value for the money ($112.00 at Midsouth). Based on the proven design of the Classic Cast press, the updated Breech Lock series adds the quick-change die bushing and an improved primer drop system. This press is strong, with cast iron frame, all-steel linkage, and 12 square inches of ram bearing surface.
Lee says this press has the “largest opening and the longest stroke in the industry” among O-frame type presses. The handle can be mounted on either side. We love the fact that the handle angle can be adjusted, as well as the lever arm length — that allows you to adjust travel and leverage to suit your preference. Smart engineering.
The new spent primer drop features a large-diameter hollow ram with clear hose that drops primers straight to a bin — that’s simple and effective. The press is very rigid and the base is wide enough for good stability. We have one of these Classic Cast Breech Lock Presses in our reloading room and it works well.
A while back, RifleShooter online magazine published a list of the purported Ten Best Bolt-Action Rifles of All Time. Ten classic rifle designs (including the Remington 700 and Winchester Model 70) were featured with a paragraph or two explaining their notable features.
“Best” Lists Stir Controversy…
These Top 10 lists are always controversial. While most readers might approve of half the entries, there are always some items on the Top 10 list that some readers would challenge. Here is RifleShooter’s Top 10 list. What do you think? Are there some other bolt-actions that are more deserving?
1. Springfield M1903
2. Mauser 98
3. Winchester Model 70
4. Remington Model 700
5. Weatherby V
6. Sako L61/AV
7. Savage Model 110
8. Ruger M77
9. Tikka T3
10. Mannlicher-Schonauer
The U.S. Army Marksmanship Unit (USAMU) has published a series of reloading “how-to” articles on its Facebook Page. This post explains how to uniform primer pockets and remove burrs in flash holes. These brass prep operations can help ensure greater consistency, shot after shot. Visit the USAMU Facebook Page for other, helpful handloading tips.
Primer Pocket and Flash-Hole Conditioning
This week, we’ll address a question that frequently arises: “Do you uniform primer pockets and deburr flash-holes?”
As we tailor our handloading methods to the specific needs of each instance, the answer, not surprisingly, is “occasionally!” Generally, the USAMU Handloading Shop does not uniform primer pockets (PP) or deburr flash holes (FH) of our rifle brass. That’s not to say we’re against it — rather, it reflects the very high volume of ammunition loaded, the fact that very few cases are ever re-loaded for a second firing, and the types of brass we use. However, as a need is perceived, we DO deburr flash holes (of which, more later.)
As to the type cases we use, many thousands of our long-range 5.56x45mm cases come to us from the arsenal with the primer of our choice pre-installed and staked in per their usual practice. Obviously, we could not uniform either FHs or PPs on this live-primed brass. However, after careful sorting, inspection and preparation, we do obtain match-winning results with it. Regular readers have seen photos of some of the tiny 1000-yard test groups we’ve fired with weight-selected domestic brass which had neither Primer Pockets uniformed nor flash holes deburred.
Figure 1 shows a fired, deprimed 7.62×51 case with primer residue intact. In Figure 2, the primer pocket has been uniformed to SAAMI specs. Note the shiny finish — evidence of the metal removed to uniform and square the primer pocket.
Shooters who reload their brass several times may decide to uniform PPs and deburr FHs, especially on their “300-yard and beyond” brass. Unlike us, they will be using their cases many times, while the operations are only needed once. Also, most handloaders only process a relatively moderate amount of brass compared to our 20-thousand round lots. Having high quality Long Range (LR) brass helps. Many of the better brass manufacturers form their flash holes so that no burrs are created.
Still, it does pay to inspect even THESE manufacturer’s products, as occasional slips are inevitable. Very rarely, some of these makers will have a significant burr in, say, 1 per 1000 or 2000 cases, and it’s worth catching those. Recently, we began processing a large lot of match brass from a premier manufacturer, and were startled to find that every case had a burr in the FH — something we’d never before seen from this maker. We then broke out the FH deburring tool and went to work.
For those who do opt for these procedures, note that various tool models may have adjustable depth-stops. Pay attention to the instructions. Some flash hole deburring tools which enter the case mouth, not the primer pocket, depend on uniform case length for best results.
Does It Really Make a Difference?
It can be difficult to truly verify the contribution to accuracy of these procedures, particularly when firing from the shoulder, in conditions. Members of this staff, as individual rifle competitors, do often perform these operations on their privately-owned LR rifle brass.
One could ascribe this to the old High Power Rifle maxim that “if you think it helps, then it helps”. Another thought is to “leave no stone unturned” in the search for accuracy.
However, an extremely talented World Champion and Olympic Gold/Silver medalist commented on his own handloading (for International competition, which demands VERY fine accuracy). He noted that he did seem to see a decline in accuracy whenever he did not uniform FH’s, deburr FH’s and clean primer pockets before each reloading; however, with the wisdom of decades’ experience, he also remarked that “It could have been that I just wasn’t shooting as well that day.”
The U.S. Army Marksmanship Unit (USAMU) regulary publishes “how-to” articles on the USAMU Facebook page. One informative “Handloading Hump Day” article covers chronograph testing and statistical samples. We highly recommend you read this article, which offers some important tips that can benefit any hand-loader. Visit the USAMU Facebook page next Wednesday for the next installment.
Chronograph Testing — Set-Up, Sample Sizes, and Velocity Factors
Initial Chronograph Setup
A chronograph is an instrument designed to measure bullet velocity. Typically, the bullet casts a shadow as it passes over two electronic sensors placed a given distance apart. The first screen is the “start” screen, and it triggers an internal, high-speed counter. As the bullet passes the second, or “stop” screen, the counter is stopped. Then, appropriate math of time vs. distance traveled reveals the bullet’s velocity. Most home chronographs use either 2- or 4-foot spacing between sensors. Longer spacing can add some accuracy to the system, but with high-quality chronographs, 4-foot spacing is certainly adequate.
Laboratory chronographs usually have six feet or more between sensors. Depending upon the make and model of ones chronograph, it should come with instructions on how far the “start” screen should be placed from one’s muzzle. Other details include adequate light (indoors or outdoors), light diffusers over the sensors as needed, and protecting the start screen from blast and debris such as shotgun wads, etc. When assembling a sky-screen system, the spacing between sensors must be extremely accurate to allow correct velocity readings.
Statistics: Group Sizes, Distances and Sample Sizes
How many groups should we fire, and how many shots per group? These questions are matters of judgment, to a degree. First, to best assess how ones ammunition will perform in competition, it should be test-fired at the actual distance for which it will be used. [That means] 600-yard or 1000-yard ammo should be tested at 600 and 1000 yards, respectively, if possible. It is possible to work up very accurate ammunition at 100 or 200 yards that does not perform well as ranges increase. Sometimes, a change in powder type can correct this and produce a load that really shines at longer range.
The number of shots fired per group should be realistic for the course of fire. That is, if one will be firing 10-shot strings in competition then final accuracy testing, at least, should involve 10-shot strings. These will reflect the rifles’ true capability. Knowing this will help the shooter better decide in competition whether a shot requires a sight adjustment, or if it merely struck within the normal accuracy radius of his rifle.
How many groups are needed for a valid test? Here, much depends on the precision with which one can gather the accuracy data. If shooting from a machine rest in good weather conditions, two or three 10-shot groups at full distance may be very adequate. If it’s windy, the rifle or ammunition are marginal, or the shooter is not confident in his ability to consistently fire every shot accurately, then a few more groups may give a better picture of the rifle’s true average.

If you are not yet familiar with the many unique features of the Forster Co-Ax, we recommend you watch the video above, a very thorough video review by Rex Roach. This shows how the press operates and highlights the design elements which set the Co-Ax apart from every other reloading press on the market. This 14-minute video shows the key Co-Ax features, explaining how the floating case-holder jaws work (3:30 time-mark), how the dies are held in place (4:40 time-mark), how spent primers are captured (6:10 time-mark), and how to set the primer seating depth (10:00 time-mark). We’ve used a Co-Ax for years and we still learned a few new things by watching this detailed video. If you are considering purchasing a Co-Ax, definitely watch this video start to finish.
Nearly every serious hand-loader has owned or used the RCBS Rock Chucker press. This Editor still uses a Rock Chucker passed down by his brother 20 years ago. And yes, it is still going strong. The latest Rock Chucker Supreme single-stage press features an improved “upside-down Y-path” dual-bin spent primer catcher. Otherwise the Rock Chucker Supreme remains big, strong, versatile and sturdy. It has very strong linkages, with a compound leverage system providing plenty of power — FL-sizing is a breeze even with large, magnum cases. The 1″-diameter ram has 12.5 sq. inches of ram-bearing surface.
The Lee Classic Cast Breech Lock Press offers excellent value for the money (
