Most of us assume that if we weigh our powder carefully (down to the tenth of a grain or less) we can achieve a uniform powder fill from case to case in our handloads. Weighing does ensure that the weight of the propellant in each case is the same, but is the column of powder the same by volume each time? “Not necessarily” is the answer. An interesting experiment by our friend Boyd Allen demonstrates that the manner in which you place kernels in the case can make a significant difference in the height of the powder column within the brass case.
Using a Gempro 250 scale, Boyd measured exactly 30.6 grains of Vihtavuori N-133 powder. He then inserted this powder in the same cartridge case multiple times. (The case has a fired primer in place.) But here is the key — Boyd used various filling techniques. He did a slow fill, and a fast fill, and he also experimented with tapping and drop tubes. What Boyd discovered was that you can start with the exact same weight of powder (in fact the very same set of kernels), yet end up with vary different fill heights, depending on how you drop the kernels into the case. Look at the photos. Despite variations in lighting, the photos show the same 30.6 grains of powder, placed in the same cartridge, with four different methods.
Using funnels with long drop tubes packs kernels more tightly, creating a shorter powder column. That allows you to get more propellant (by weight) into the case.
Boyd Explains the Procedure Used for his Experiment.
EDITOR’s NOTE: So there is no misunderstanding, Boyd started with a weighed 30.6 grain charge. This identical charge was used for ALL four fills. After a fill the powder was dumped from the case into a pan which was then used for the next fill technique to be tried. So, the powder weight was constant. Indeed the exact same kernels (of constant weight and number) were used for each fill.
Boyd writes: “I used the same powder for all fills, 30.6 gr. on a GemPro 250 checked more than once. All fills employed the same RCBS green transparent plastic funnel. The fast drop with the funnel only overflowed when it was removed from the case neck, and 15 granules of powder fell on the white paper that the case was sitting on. The fast-funnel-only drop with tapping, was done with the funnel in place and the case and funnel in one hand, while tapping the case body with the index finger hard, many times (about 20 fast double taps). My idea here was to “max out” the potential of this tapping technique.
The slow drop with the funnel and 10″-long .22 cal. Harrell’s Precision drop tube, was done by holding the scale pan over the funnel and tapping the spout of the pan repeatedly on the inside of the funnel about 1/3 down from the top, with the scale pan tilted just enough so that the powder will just flow. Many taps were involved, again, to max out the technique.
Again, to be clear, after each case filling, the powder was poured from the case back into the scale pan carefully. You may notice the similarity between the fast drop with the drop tube, and the funnel only with tapping. Although I did not photograph it, fast tube drop and tapping (combined) improved on tapping alone, but only to about half as far down the neck as the slow with drop tube. Due to the endless possible permutations, I picked four and left it at that.
I believe that I can make the rough judgment that the scale pan funnel and drop tube technique, which involved a longer drop period, and probably less velocity at the top of the tube, left more room in the top of the case neck than the slow drop from the measure with the same drop tube. You have both pictures, so you can make the comparison.” — Boyd
Does Powder Column Height Variance Make a Difference?
Boyd’s experiment proves pretty conclusively that the method of dropping a given weight of powder can affect the height of the powder column in the case and the degree of powder compression (when a bullet is seated). He showed this to be true even when the exact same set of kernels (of constant weight) was used in repetitive loadings. This raises some interesting questions:
1. Will subsequent cartridge transport and handling cause the powder to settle so the variances in powder column height are diminished?
2. If significant inconsistencies in powder column height remain at time of firing, will the difference in fill level hurt accuracy, or result in a higher extreme spread in velocity?
3. Is there any advantage (beyond increased effective case capacity) for a tight (low level) fill vs. a loose (high level) fill?
We don’t know the answer to these follow up questions. This Editor guesses that, if we tested low-fill-height rounds vs. high-fill-height rounds (all with same true fill quantity by weight), we might see meaningful differences in average velocity. I would also guess that if you fired 10 rounds that exhibited quite a difference in powder column heights, you might see a higher ES/SD than if you shot 10 rounds loaded with a very consistent powder column height (either high or low). But further testing is needed to determine if these predictions are true.
This month USA Shooting celebrates 30 years as the American Governing Body for shooting sports within the U.S. Olympic and Paralympic Committee. USA Shooting will commemorate its anniversary throughout 2025 with special events, social media giveaways, and initiatives designed to further expand participation in competitive shooting sports. To learn more about USA Shooting’s 30th Anniversary programs, visit USAShooting.org and follow @USAShooting on Facebook, X, and Instagram.
“These three decades represent not just organizational longevity, but a remarkable journey of athletic excellence… and competitive innovation,” said Kelly Reisdorf, CEO of USA Shooting. Since its founding in 1995, USA Shooting has guided American marksmen and markswomen to 36 Olympic and Paralympic medals, developing world-class talent across all shooting disciplines.
“The trajectory of American competitive shooting has been defined by both winning at the highest levels and developing tomorrow’s champions,” said Tim Rupli, Chairman of USA Shooting. “We’ve cultivated American talent while championing the values of precision, discipline, and patriotic excellence[.]”
A Legacy of Champions
For three decades USA Shooting has produced shooting sports legends, including Kimberly Rhode, a 6-time Olympic medalist, and Vincent Hancock, the first shooter to win four gold medals in the same event. Most recently, USA Shooting athletes excelled at the Paris 2024 Olympic and Paralympic Games, securing six medals — including gold for Hancock in Men’s Skeet, silver medals for Sagen Maddalena in Women’s 50m Rifle 3 Positions, Conner Prince in Men’s Skeet, Austen Smith and Hancock in Mixed Skeet Team.
The legacy extends to stellar coaches like Lloyd Woodhouse, whose 23-year leadership of the U.S. shotgun team produced 10 Olympic medals across four Games and earned him recognition as the 2003 U.S. Olympic and Paralympic Committee Coach of the Year.
From Amateur Act to Global Force
USA Shooting traces back to the Amateur Sports Act of 1978, which established the National Rifle Association of America as the governing body for shooting sports. The mid-1980s saw the establishment of the U.S. Olympic Shooting Center and Olympic Shooting Park in Colorado Springs, creating a permanent home for the U.S. Shooting Team.
Looking Ahead: The 2028 Olympics in Los Angeles
As the organization celebrates its past, USA Shooting remains focused on the future — particularly the Los Angeles 2028 Olympic and Paralympic Games, which will mark the first Summer Olympics on American soil in over three decades. “Having the summer Games return to the United States presents an unprecedented opportunity to showcase our sport and athletes to a home audience,” Reisdorf added. “We’re positioning USA Shooting for its most successful Olympic cycle in our history.”

A while back, we featured a portable reloading bench built on a Black & Decker Workmate. That proved a VERY popular do-it-yourself project so we’re showing it again, in case you missed it the first time.
Texan Robert Lewis made himself a great portable reloading bench from plywood mounted to a Black & Decker Workmate 225. The bench, roughly 22″ x 19″ on top, folds up to fit easily in your car’s trunk or behind the seats in a pick-up truck cab. Four recessed bolts hold the wood top section to the collapsible B&D Workmate. The sides and back of the unit are attached to the base with small nails. There is a small shelf (also nailed in place) which can be used to clamp a powder measure or hold a scale. Shown in the photo is a Harrell’s Benchrest measure and Harrell’s single-stage “C” press.
Originally, the whole unit could be built for about $65.00 with pine, or $80.00 with oak (as shown). Robert explained: “The Workmate was $40. If someone bought a 2’x4′ sheet of 3/4″ oak plywood, I think it is around $30. Using pine plywood would be about half that. Fasteners were $3. Spar Urethane would be $5.” [Editor: We have seen major inflation — the Workmate is now about $80 and you’ll be spending more for the wood, so figure the whole project might be $150.00.]
Robert told us: “I used a couple ideas I found on the web. The Larry Willis website gave me the idea to use the Black and Decker Workmate as a base. I found the Workmate on sale for $40 and the top is made from oak plywood I had in my shop. I sealed the wood with three coats of Spar Urethane. The whole thing folds into a nice package for transportation to and from the range.”
NOTE: Since we first ran this story, the price of a Black & Decker Workmate WM225 has increased substantially. But good news — Amazon is currently selling WM225-A Workmates for $74.99, a decent price, particularly for Prime members who get FREE shipping. And for $79.34 at Home Depot, you can get the Workmate WM225 with Local Store Pickup or home delivery (in most states).
In the past the U.S. Army Marksmanship Unit published a series of reloading “how-to” articles on its USAMU Facebook page. One “Handloading Hump Day” article covered two basic case prep chores — uniforming primer pockets and deburring flash-holes. Visit the USAMU Facebook page for other tips.
Primer Pocket & 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 “Sometimes!” However, don’t flip that dial just yet, as what determines our approach may be helpful in deciding how to address one’s own techniques. Moreover, we have a buried “Easter Egg” morsel that may bring a chuckle, as well as useful safety information!
Generally, the USAMU Handloading Shop does not uniform primer pockets (PP) or deburr flash holes (FH) of our rifle brass. We’re certainly not against it… Rather, this reflects the very high volume of ammunition we load, 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 interest, we have fired many very small, 1000-yard test groups and aggregates using weight-selected, domestic brass that had not had PPs uniformed or FHs deburred.
Before and After — On the left is a fired, deprimed 7.62×51 case with primer residue intact. On the right the primer pocket has been uniformed to SAAMI specs. Note the shiny finish at the bottom of the pocket — evidence of the the removal of metal when uniforming the primer pocket.
As to the type cases we use, many thousands of our long-range 5.56mm cases come to us from the arsenal with the primer of our choice pre-installed and staked-in, per usual practice. Obviously, we cannot 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.
Shooters who reload their brass several times may decide to uniform PPs and deburr FHs, especially on their “300-yard and beyond” brass. Here, they will use the cases many times, while the uniforming is performed only once. Also, most handloaders only process moderate amounts of brass, compared to our multi-thousand round lots.
Having high quality Long Range (LR) brass helps. Many of the better brass manufacturers [make] 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 the best makers will have a significant burr in, say, 1 per 1000 or 2000 cases, and it’s worth catching those.
Exceptions can always be found. Recently, we began processing a large lot of match brass from a premier manufacturer. We were startled to find that every case had a significant burr in the FH — something we’d never before seen from this maker. We then broke out the FH deburring tools and went to work.
Some observers have noted that 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.”
However, a World Champion and Olympic Gold/Silver medalist here 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 FHs, deburr FHs and clean primer pockets before each reloading. (One might be tempted to counter that only a truly World Class shooter could reliably detect the difference.) However, with the wisdom of decades experience, our Champion also remarked that “It could have been that I just wasn’t shooting as well that day.”
For those who do opt for these procedures, note that various tool models may have adjustable depth-stops; pay attention to the instructions. Some FH-deburring tools (which enter the case mouth, not the primer pocket) are dependent upon uniform case length for best results.
Above is a flash-hole deburring tool on an RCBS powered case-prep unit. These case prep machines can save a lot of pain and misery, helping one perform various functions quickly and efficiently.
Wipe-Out foam bore cleaner is a product we’ve used with great success on many rifles. With sufficient dwell time, it removes both carbon and copper fouling. You can combine it with Wipe-Out Accelerator or Patch-Out liquid to speed up cleaning time. Many shooters, including this editor, find that bore-brushing has been virtually eliminated with the regular use of Wipe-Out. (With some barrels however, you may still have to brush or use a bore paste if you notice stubborn carbon build-up in the throat area.)
CLICK HERE for full official instructions on use of Wipe-Out foam applied from the muzzle or the breech.
Method One: Apply Through Muzzle
Out standard procedure with Wipe-Out is to insert an O-ring-sealed cleaning rod guide into the chamber and then squirt through the muzzle in short puffs. Put a towel or rag on the comb of your stock and watch for a little bit of foam to exit the rod guide. We usually wait 30 minutes for the bubbles to dissipate, then do a second foam application. Be sure to clean off any excess foam before it drips on your stock. It is important to keep the foam off fine wood or paint finishes.
Our actual routine normally starts with 3-4 wet patches with Carb-Out (to get the loose black stuff out), followed by the two foam cycles as explained above. Then we plug both ends of the barrel, drive home from the range and dry-patch out on arrival at the house. If the gun is going to be used again soon, that’s all we do. If there will be long-term storage we’ll run some Eezox down the bore.
Method Two: Apply Wipe-Out from Breech
You can also apply Wipe-Out from the breech. To allow breech-first application, Wipe-Out cans now come with a short plastic tube and a plastic tip that fits in your chamber. These can also be purchased separately for $2.50. However, we’ve found the plastic tip is too big for some chambers and it is not always easy to get a good, secure seal even if it does fit. Jason Baney has come up with a solution. READ Jason’s Wipe-Out Article.
Use Fitted Tubing for Breech-First Applications of Wipe-Out
You can apply Wipe-Out through the breech very effectively if you use fitted, plastic tubing. While this works well for bolt-actions, breech application is particularly handy for the Garand, M1A and other semi-autos. Jason Baney has written a short article describing this process. In a nutshell, you need one piece of tubing that fits the chamber tightly and then connects with a second, smaller diameter tube that attaches to the Wipe-Out can. This avoids any “over-spray” of foam in the action area, providing a clean, simple solution. Just squirt for a second or so, and wait for white foam to come out of the muzzle. Be sure to keep Wipe-Out off fine wood stocks.

The National Shooting Sports Foundation (NSSF) has prepared tips for gun owners transporting firearms in their vehicles. Whenever you are driving with guns (of any kind), the firearms should be transported securely. In some states, the firearms must be in locked cases inside the vehicle. And, with the rise of break-ins on parked vehicles, it’s important to keep gun cases out of sight if possible. This article has tips on safe and secure gun transport.
HERE Are Key Guidelines for Safe, Secure Handling of Firearms in Vehicles:
• Take note of and safely control the muzzle direction of firearms in vehicles. This is one of the main rules of gun safety and applies to the inside of vehicles as well as any other location.
• When finished using your firearm outside your vehicle, unload it before you re-enter your vehicle.
• Even after a long hunt or a day in the sun at the range, always check, and then double check, that guns are unloaded before placing them in a car or truck.
• Be very careful if you must unload a firearm in the confined space of a vehicle so as not to have an accidental discharge. If your location allows, it is safer and easier to unload the firearm outside the vehicle.
• Never leave firearms in parts of the vehicle accessible to children or pets.
• Keep firearms and ammunition out of sight to avoid tempting thieves.
• Use secure temporary storage for firearms in vehicles.
• A lockable gun case or a lock box may be the most practical choice to securely store a gun in a vehicle. These come in a range of prices and models.
• If you’re concerned about quick access to your firearm, many types of lockable safes allow for extremely fast access of your gun while at the same time helping to prevent unauthorized access.
• Secure the lock box to the vehicle, if possible. Some companies make custom concealed compartments for specific model vehicles.
Storing Firearms in Vehicles to Prevent Theft and Misuse
We travel with our firearms all the time, taking them to the range, on hunting trips or carrying them on our person, as permitted by law. When you are transporting guns, the last thing you want is to have your gun stolen and potentially misused by a criminal. In some states, you could even be subject under the law to serious penalties and fines for failure to properly secure a firearm. Unfortunately, thefts of firearms from vehicles are on the rise. Thieves commonly steal cars and trucks even when they don’t obviously contain firearms — a reminder that vehicle door locks are not totally secure.
When you are not in your vehicle, all firearms should be placed in locked storage and out of sight. Locking the doors on your vehicle does not constitute secure firearm storage. As one writer put it: As one writer put it: “Cars and trucks aren’t safes. And they’re not holsters. They’re not storage containers.”
The glove compartment or console of your vehicle, even if lockable, should not be considered a secure storage device either, as it can be pried open quickly and is the first place a thief might look. If you need to leave a handgun in a vehicle, we recommend putting the guns in secure case, preferably out of sight. Many vehicles have a compartment, above the spare tire storage recess, which can be secured.
For our readers who are stuck at home under government orders, we are reprising a video feature about hunting in Norway. For those whose horizons have been limited due to the “shelter at home” response to the Coronavirus pandemic, we offer this getaway to scenic Vesterålen in northern Norway…
This is one of the finest shooting videos we’ve ever seen. Set in the scenic Vesterålen archipelago of northern Norway, this high-quality 15-minute video is part National Geograhic travelog, part ballistics lesson, part gear review. Given the current COVID-19 lockdowns, we wish we had the opportunity to join Ulf Lindroth and Thomas Haugland on their remarkable shooting adventure. This video was originally created for Great Britain’s Fieldsports TV Channel.
This is an outstanding video, recommended for anyone interested in long-range hunting.
Long range shooters Lindroth and Haugland traveled to the Arctic Circle to field test a new .338 LM Blaser R8 (in GRS stock) fitted with a Zeiss Victory V8 4.8-35x60mm scope. (Ammo is Norma-brand .338 Lapua Magnum). The video shows how they confirm the ballistics of the Norma factory ammo in the Blaser R8 rifle system.
Ulf and Thomas initially test out the system confirming drop at multiple yardages, and then use the rifle for practical accuracy. Ulf says: “If you know your hunting will demand a long shot, and you want to push the limit but still be sure to make the first-shot kill… If you want to do an ethical hunt, if you want to push that limit, you have to do [this kind of testing].”
Ulf Lindroth (above) observed: “We shot [at 808 meters] observed the misses, clicked our way into the target, and now we have the true drop at that distance… in this air pressure, in this temperature. From there we can start working to find our TRUE trajectory. And when we have THAT… we can get serious about some target shooting.”
.338 Lapua Magnum — Big-Bore High-Performance Cartridge
From WikiPedia: The .338 Lapua Magnum (aka 8.6×70mm) is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. Due to its use in the War in Afghanistan and the Iraq War, the cartridge has become widely available. The loaded .338 LM cartridge is 8.6 mm (0.34″) in diameter and 93.5 mm (3.68″) long. Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies 2,890 fps to 3,000 fps for commercial loads with 250gr bullets.
Our friend Jim See of Elite Accuracy LLC tested the depth-adjustable hand priming tool from Frankford Arsenal. This product, called the Platinum Series Perfect Seat Hand Primer has some unique features. Primer seating depth can be adjusted with a handy wheel in the tool’s center handgrip. Each “click” of the wheel moves the primer post .001″ (one one-thousandth of an inch). Additionally, the design of the case-holder allows quick and easy removal of a primed case. The unit ships with a full set of shell-holders to match all types of cases. Like many other hand priming units, the primers are loaded into a flip tray that attaches to the head of the tool.
Here is Jim See’s quick review of the Frankford priming tool:
“The Frankford Arsenal perfect hand-priming tool is legit. The tool is built heavy and strong. The only plastic parts in it are the tray and lid. The [primer] seating depth adjustment… is simple and accurate. Easy to operate. I primed 1000 cases, averaging 23 per minute. I adjusted the depth of seating between two different lots of brass in seconds. The system seats primers easily with one hand operation. The cases slide out on their own after seating. Insert, seat, reach for a new case at the same time as you are operating the lever, case slides out and you are inserting the next piece.”
Overall, Jim was “Super impressed with the quality and the results. This thing is super smooth — way less pressure needed than my Lee or RCBS. It’s a lot faster too.” Jim add that one can switch from small to large primer posts in 10-15 seconds.
This Video Shows the Frankford Priming Tool in Operation:
Even with premium brass you may want to adjust your primer seating depth: “Every thing has a tolerance that is acceptable in manufacturing. If primer pocket depth has a .005″ tolerance and the primers themselves have a .002″ tolerance you can see why adjustments would be needed. In this case the two lots were manufactured on year apart. Could you expect them to be identical?”
A while back, we featured a portable reloading bench built on a Black & Decker Workmate. That proved a VERY popular do-it-yourself project so we’re showing it again, in case you missed it the first time.
Method Two: Apply Wipe-Out from Breech
