It’s official. Representatives of Lapua announced at SHOT Show 2014 that Nammo has purchased Vihtavuori, acquiring the “VV” line of propellants, and, most importantly, taking over Vihtavuori’s powder production facility in Vihtavuori, Finland.
This means that Vihtavuori is now officially under the Nammo umbrella as is Lapua, producer of brass, bullets, and loaded ammunition. Lapua engineer Tommi Tuuri has visited the Vihtavuori plant in person. Tommi says all operations are going well and the plant is running at normal capacity (but Nammo does plan some upgrades in the months ahead). Vihtavuori powders will continue to be imported into the United States as before and the powders will be made available through existing distribution channels.

Story by Boyd Allen
While many top competitive shooters trickle their stick powder charges to a kernel or two, that would be impractical when loading charges for giant naval guns. You may be surprised, but the shells fired by the U.S. Navy’s massive 14″ and 16″ naval guns were also propelled by stick-type extruded powders. You couldn’t trickle these ‘kernels’ though — a single stick or ‘grain’ can be over 2″ long. Take a look…
In connection with a Benchrest Central discussion that drifted to the subject of powders used in large naval guns, I heard from Joe McNeil, whose father was involved in manufacturing those very propellants as a DuPont employee. Joe writes:
“My Dad worked for the DuPont company for over 40 years. Every time the nation went to war he was assigned to the gun powder plants which DuPont ran for the government for $1.00 per year! His last assignment was at the Indiana Ordnance Plant in Jefferson, Indiana from 1952 through 1958. He had a display case made of all of the different powders made at the plant and left it to me. That’s why I have a grain of 16″ gun powder. He took me out to the Jefferson proving grounds once when they tested the powder in a 16″ gun. We watched from a half-mile away but it left a lasting impression when they fired that gun. They actually had a set of rings they fired through to test the performance of the powder and shell. This was a truly fond memory of my Dad and his work.”
Here are some pictures of the gun powder “grains” made during the Korean War at the Indiana Ordnance Works where Joe McNeil’s father worked.
Above is the display case with the different powders manufactured at the DuPont plant. They include: 37 MM/AA, 75MM Pack Howitzer, 50 Cal. 5010, 20 MM 4831, 30 Cal. 4895, 76 MM, 3″, 5″, 90 MM, 4.7″, 240MM, 8″, 280 MM, 175 MM, 155 MM Howitzer, 155 MM Gun M.P., 8″ Gun M.P., 12″, 14, 16″. There are different-sized ‘grains’ for specific rounds.

21st Century Shooting produces a high quality powder funnel, that is very “user-friendly”. The top section is precision ground and polished for a smooth flow. The center has a see-through tube so you can watch the progress of your powder dropping into the case. At the bottom of each funnel is a black case adapter that seats securely yet won’t get stuck on the case. There are five different adapter sizes — the smallest fits .17 Rem to .223 Rem, while the largest fits big magnum calibers. We use the mid-sized, #3 adapter most often. This fits 6mmBR, 6.5×47 Lapua, and .308 Win family of cases (.243 Win, .260 Rem, 7mm-08, .308 Win). Additional adapters are $6.99 each. There are three tube lengths available: 3″, 6″, and 10″. So, if you need an extra-long drop tube (to help fill PPC and other small cases), 21st Century has you covered.
The funnels are priced by size. The 3″-long model is $24.00, the 6″-long model is $27.00, and the big 10″-long model is $31.00. Prices include one (1) adapter. These high-grade funnels will help you load faster and easier, with fewer spilled kernels. We use these funnels and they do work well. The appropriate collars fit your .223 Rem, 6PPC, 6mmBR, Dasher, 6XC, .260 Rem, .284 Win, and .308 case necks just right — not too loose, not too tight. Kernels flow smoothly through the tube without sticking to the sides. The aluminum top section does not seem to attract a static charge so you don’t have to waste time brushing kernels off the funnel after use. We like this product. For high-volume precision reloaders, these funnels are worth the money.

If you own an RCBS ChargeMaster 1500 electronic powder scale/dispenser, or are thinking about purchasing one, here are a few tips that can cut your loading times and eliminate some petty annoyances.
Mute That Annoying Beep
Some ChargeMaster users complain about the loud beep at the end of each cycle. There’s a simple way to silence the beep — and you don’t have to cut any wires or permanently disable the speaker. To mute the beep, simply hold down the Zero button until “beep off” displays. Repeat this procedure to restore the beep function.
Activating the Auto-Dispense Mode
You can set the ChargeMaster to automatically dispense your pre-programmed charge as soon as you put the pan back on the scale. Simply press and hold the “Enter” button. The code “Auto” should then appear on the display. At this point, push “Disp” to dispense the first charge. When you replace the pan, the unit will automatically dispense the same charge. For some people this is an added convenience. You can always go back to the default manual dispense method by changing the dispense mode using the “Enter” button again.
Use a McDonald’s Straw to Reduce Over-Throws
Jaco Brink provided another useful tip to avoid “over-throws” (excess charge weight): “The RCBS employee advised me to take a McDonnell’s straw (because it is thicker than a normal straw), cut off about a half inch piece and put it into the tube where the powder exits. This caused the last part of an extruded powder to cluster less, and reduced the amount of overthrows dramatically.”
The video below shows how to set up and calibrate a Chargemaster 1500. Be sure to level the unit carefully, both left to right and front to back. Starting at the 1:44 mark in the video you can see the unit dispense a 50-grain charge in 30 seconds. The slow, final trickle stage takes about half of the total time.
How to Shorten Dispensing Times
The last tip is for advanced users only. You can alter the programming settings to speed up powder dispensing dramatically. One user reported that, by re-programming his machine, his cut his dispensing time for a 30-grain load from 22 to 13 seconds “with no overthrows”. WARNING: once you change the parameters, there is no “restore” command to set everything back to the defaults. So proceed carefully. The speed enhancement procedure is described on the pages linked below:
Here’s good news for purchasers of reloading components. Powder Valley Inc. (PVI) is “holding the line” on prices of powder, primers, brass, and bullets. In so doing, Powder Valley is “keeping the faith” with its customer base. By contrast, many local gun shops and big box retailers have jacked up prices on guns, ammo, and reloading supplies in response to a spike in demand. With the hue and cry for new gun control legislation, gun owners have rushed to stores to get guns, ammo, and reloading components. Predictably, some retailers have raised prices on everything from primers to all types of semi-auto firearms. Not so with Powder Valley. If you check the PVI website, you’ll see that prices for almost all products in stock are basically the same as a month ago (before the events in Newtown). Unlike some other vendors, Powder Valley has refrained from ramping up prices. We commend PVI for this.
Here is what Powder Valley owner Bryan Richardson told us about his company’s pricing policy:
“We watched back in 2009 as companies jacked up their prices due to supply and demand. This may make sense for some retailers and manufacturers. However, this is not the way we do business, nor will ever do business. It is completely against our conviction.
My wife and I established our business in 2000 with a mission statement of: ‘Providing the finest in reloading components and other shooting sports related products at the best possible price. In doing so, we will conduct business with the utmost respect and consideration for the customer’s needs by constantly demonstrating honesty and integrity.’
Therefore, increasing prices due to current market and political conditions is contrary to our mission of conducting business with the utmost respect and consideration for the customer’s needs. It is my opinion that if we want our industry to survive… we cannot price consumers out of shooting. Therefore, when you see our prices increase or decrease it is simply based off of the manufacturer’s or importer’s pricing. I think history shows that consumers remember the companies who elevated their prices for short-term profits and those who did not. We are here for the long haul and want to grow our business through building our customer base, not increasing our prices.”

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.
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.

Here’s a clever, easy modification for your RCBS ChargeMaster electronic powder dispenser. Many folks use a McDonald’s straw to smooth kernel flow out of the dispensing tube. Forum member Mike S. (aka in2deep) found that, even with a straw in place, he sometimes got clumps, which dropped 5-6 kernels at once, throwing off his dispensed weight.
Mike looked at the situation and ingeniously decided to trim the straw into little v-shaped arms or prongs. This helps to break up the clumps, so the kernels flow out the end of the tube more consistently during the dispense cycle. Mike writes:
Soda Straw Modification
This is a further tweak of the popular soda straw modification as the original mod would still allow Varget powder to collect in the straw and dump sometimes as many as 6 or 8 or even more extra kernels in the pan. It would sometimes signal an overcharge, but even when it didn’t there could be as many as 6+ kernels too high or too low (total spread of 12+).
The little arms (prongs) on the straw tend to separate the kernels into groups of 1 or 2 or 3 and prevents piling and many times the throw is now within 1 or 2 kernels of the desired weight.
Straw Cutting Tips — Mike found the shape/angle of the “arms” is very important. If the cuts are too fine or too course it allows the kernels to collect almost like before but the illustrated angle seems to allow an average of only 2 or 3 kernels per trickle input from the machine. This means that more charges are much closer to the actual desired weight and max kernel variances will be cut in less than half and there will be almost no overthrows.

How much does it cost you to send a round downrange? Ask most shooters this question and they’ll start adding up the cost of components: bullets, powder, and primers. Then they’ll figure in the cost of brass, divided by the number of times the cases are reloaded.
For a 6BR shooting match bullets, match-grade primers, and 30 grains of powder, in brass reloaded ten times, this basic calculation gives us a cost per shot of $0.51 (fifty-one cents):
NOTE: If you shoot a larger caliber that burns more powder, and uses more expensive bullets and/or brass, your total cost per round will be higher than $0.51.
$1.00 Per Shot True Cost? Yikes!
OK, we’ve seen that it costs about $0.51 per round to shoot a 6BR. Right?
Wrong! — What if we told you that your ACTUAL cost per round might be closer to double that number? How can that be? Well… you haven’t accounted for the cost of your barrel. Every round you fire down that tube expends some of the barrel’s finite life. If, like some short-range PPC shooters, you replace barrels every 700 or 800 rounds, you need to add $0.60 to $0.70 per round for “barrel cost.” That can effectively double your cost per round, taking it well past the dollar per shot mark.
Calculating Barrel Cost Per Shot
In the table below, we calculate your barrel cost per shot, based on various expected barrel lifespans.
As noted above, a PPC barrel is typically replaced at 700-800 rounds. A 6.5-284 barrel can last 1200+ rounds, but it might need replacement after 1000 rounds or less. A 6BR barrel should give 2000-2600 rounds of accurate life, and a .308 Win barrel could remain competitive for 4,000 rounds or more.
The table below shows your barrel cost per shot, based on various “useful lives.” We assume that a custom barrel costs $540.00 total to replace. This includes $300.00 for the barrel itself, $200.00 for chambering/fitting (conservative number), and $40.00 in 2-way shipping costs. These are typical costs shooters will encounter when ordering a rebarreling job.
The numbers are interesting. If you get 2000 rounds on your barrel instead of 1000, you save $0.27 per shot. However, extending barrel life from 2000 to 3000 rounds only saves you $0.09 per round. The longer you keep your barrel the more you save, but the savings per shot decreases as the round count increases.
How to Reduce Your TRUE Cost per Round
What does this tell us? First, in figuring your annual shooting budget, you need to consider the true cost per round, including barrel cost. Second, if you want to keep your true costs under control, you need to extend your barrel life. This can be accomplished in many ways. First, you may find that switching to a different powder reduces throat erosion. Second, if you’re able to slow down your shooting pace, this can reduce barrel heat, which can extend barrel life. (A varminter in the field is well-advised to switch rifles, or switch barrels, when the barrel gets very hot from extended shot strings.) Third, modifying your cleaning methods can also extend the life of your barrel. Use solvents that reduce the need for aggressive brushing, and try to minimize the use of abrasives. Also, always use a properly fitting bore guide. Many barrels have been prematurely worn out from improper cleaning techniques.

Man does not live by long-guns alone. We know that many of our readers own .45 ACP handguns and load for this extremely accurate “classic” cartridge. When selecting a powder for the .45 ACP, there are many good options. All the major powder manufacturers make propellants with appropriate density and burn rate characteristics for the .45 ACP. Popular choices include: AA #5 (Accurate Powder); Bullseye (Alliant); Clays, HP-38, and Titegroup (Hodgdon); VV N310 and N320 (Vihtavuori); and WW 231 and WST (Winchester). We’ve tried all those powders in a variety of .45 ACP handguns. When we consider all the factors that make for a good pistol powder, we think N320 is one of the best available propellants for the .45 ACP. Vihtavuori N320 is very accurate, it meters well, and it burns clean, with minimal smoke and flash. If you haven’t tried VV N320 yet, you should.
Pros and Cons of Different Powders for the .45 ACP
This Editor has personally tried out eight or more different powders for the .45 ACP. Bullseye works but it is very dirty (both smoke out the barrel and sooty powder fouling on case). Though it otherwise burns clean, Titegroup leaves a singular (and nasty) high-temp flame streak on your brass that is hard to remove. AA #5 is a good choice for progressive press newbies as you use more powder so a double charge will (usually) be obvious. I like AA #5 but N320 was more accurate. Clays burns clean but some powder measures struggle with flake powders like this. WW 231 offered excellent accuracy and metered well, but it kicked out sparks with little pieces of debris that would hit me in the face. Who wants that?
I personally tried all the powders listed above with lead, plated, and jacketed bullets. After testing for accuracy, consistency, and ease of metering, I selected VV N320 as the best overall performer.
No powder tested was more accurate (WW 231 was equally accurate).
Meters very well in all kinds of powder measures.
Produces very little smoke from muzzle.
Does not put nasty burn streak on brass like Tite-Group does.
Low Flash — you don’t get particles and sparks flying out like WW 231.
Cases come out from gun very clean — so you can tumble less often.
Forum member and gunsmith Michael Ezell agrees that N320 is a good choice for the .45 ACP. Mike has also found that WW 231, while accurate, produces sparks and a large flash. Mike writes: “I first started using N320 after my first night shoot, while shooting IDPA/IPSC matches. It was astonishing how much of a fireball the WW 231 created. I was literally blinded by the flash while trying to shoot a match. As you can imagine, that didn’t work out very well. I went from WW 231 to N320 and never looked back…and the flash from it was a fraction of what a kid’s sparkler would give off. I have nothing but good things to say about [N320] after using both. Night shoots are a real eye-opener! When it comes to a personal protection… there is, statistically, a very high chance that if you ever have to use a gun to protect yourself or your family, it’ll be in the darkness[.] Being blinded by muzzle flash (and deafened by the noise) are things that should be considered, IMO.”
This Editor owns a full-size, all-stainless S&W 1911. After trying numerous powders, I found VV N320 delivered the best combination of accuracy, easy metering, consistency, clean burning qualities, and low muzzle flash. My gun has proven exceptionally accurate using N320 with bullets from 180 grains to 230 grains — it will shoot as accurately as some expensive customs I’ve tried. At right is 5-round group I shot offhand at 10 yards with my 5″ S&W 1911. The bullet hole edges are sharp because I was using semi-wad-cutters. Rounds were loaded with Vihtavuori N320 and 200-grain SWCs from Precision Bullets in Texas.

Eurenco (European Energetics Corporation) is a French company owned by the SNPE Group. Eurenco specializes in production of propellants and explosives. Eurenco currently owns and operates five modern production plants in Belgium (Clermont), Finland (Vihtavuori), France (Bergerac, Sorgues) and Sweden (Bofors AB, Karlskoga). Readers are doubtless familiar with Vihtavuori powders, which are marketed and distributed by the Nammo Lapua group based in Finland. Though Nammo Lapua distributes Vihtavuori powder, Eurenco actually owns the Vihtavuori factory located in Vihtavuori, Finland.
Eurenco Looks for Buyer for Vihtavuori Plant
On June 18, Eurenco stated that it is “considering” selling the Vihtavuori Ltd. production facility to a third party. This factory currently employs 100 workers, and has annual revenues of $15 million Euros.
Eurenco hopes to sell the plant to a Finnish company, and we are informed that at least one investment group from Finland is interested. Eurenco revealed no immediate plans to shut the facility or to curtail production while Eurenco seeks a buyer. However, Eurenco said that the primary reason for selling the plant was reduced military demand for Vihtavuori products in recent years.
No Change in Vihtavuori Powder Distribution in USA
We discussed the potential Vihtavuori factory sale with Adam Braverman, U.S. representative for Nammo Lapua. Adam first noted that Nammo Lapua is NOT a potential buyer for the plant: “That’s not on the table.” But Adam emphasized that he forsees no changes to the current Vihtavuori distribution scheme: “Vihtavuori powder buyers should expect ‘business as usual’. We do not forsee any price or product availablity changes in the short term. There is plenty of powder inventory available, so we can fill all existing demands through the end of 2012.” While Eurenco looks for a new owner of the Vihtavuori plant, there will be no changes to the current system of distribution of Vihtavuori powders in the USA. Adam said: “There is plenty of powder in the European warehouses, and Nammo Lapua will continue to export Vihtavuori propellants to the USA importers (Hodgdon and Kaltron) who will distribute them to our retailers. We do not anticipate any supply shortages.”

Successful long-range shooters know that careful weighing of powder charges helps them achieve superior long-range accuracy. By maintaining powder charges within very narrow weight tolerances, hand-loaders can produce ammo with more consistent muzzle velocities from shot to shot. Low Extreme Spread (ES) and Standard Deviation (SD) numbers translate directly to reduced vertical dispersion at very long ranges (although velocity is not the only contributing factor to vertical spread). In pursuit of load weight uniformity, many of our top long-range aces have invested in the latest, high-tech magnetic force restoration (MFR) digital scales (such as the Sartorius GD503). These laboratory-grade MFR scales are extremely stable (with minimal drift) and they can reliably measure to .005 grain, that is five thousandths of a grain. That is less than the weight of one kernel of typical extruded powder. For example, with Varget, there are three to four kernels in one-tenth of one grain of Varget. That means each kernel weighs .025 to .035 grains.
With the capability of modern modern MFR scales to measure less than one-hundreth of a grain, we have a new frontier in precision reloading. You’ll note, in the preceding paragraph, we said that one-tenth of one grain of Varget is three or four kernels. Well, “which is it?” you might ask. The answer is that it might be three, or it might be four, depending on the size of the individual kernels. That’s a disturbing uncertainty that we simply had to accept… until now.
Powder Kernel Uniforming — A Breakthrough
We now have the tools and the methodology to resolve the inherent uncertainty in individual kernel weight. Using the new technique of powder kernel uniforming, first pioneered by German Salazar, we can now, for the first time, ensure that every kernel of powder that goes into a cartridge is virtually the same weight — the same, in fact, within 0.01 grain (one-hundredth of a grain) TOTAL spread.
For a reloader looking to achieve “perfect” load weight uniformity, powder kernel uniforming offers the ultimate control over powder weight. The method we devised to uniform individual kernels consists of kernel core-drilling. The propellant we chose for this kernel-uniforming test was a new prototype (not yet commercially available) EuroChemie RL “X” propellant. This was chosen because it offered relatively large, can-shaped kernels that could be drilled relatively easily.
Core-Drilling Kernels with Micro Drill-Bits
The center of each kernel was bored out with a micro-drill. But here’s the key. Before drilling, we first weighed each kernel. Then we selected a micro drill bit of appropriate diameter to achieve uniform weights. With the heavier kernels (in the 0.04 gr range) we used a larger micro-bit. With the lighter kernels (in the 0.02 range), we selected a smaller diameter micro-bit that removed less material from the center of the kernel. Obviously, many kernels were ruined while we perfected the drilling process. It required great patience and a very steady hand. But after a few dozen hours of drilling, we had a batch of uniformed kernels that were all within plus or minus .005 grains (.01 grain ES). Now we were ready to do some testing.
Proof That It Works
All this time-consuming work to drill holes in individual kernels would be pointless, of course, if it did not produce meaningful accuracy gains. The proof, as they say, is “on the target”. We were curious to see if our uniformed powder kernels would out-perform unmodified kernels, so we did some field testing. We prepared two batches of 6mmBR ammo in Lapua brass, with full case prep, and bullet base to ogive sorting (we wanted to eliminate as many variables as possible). Bullets were Lapua 105gr Scenar Ls, which proved to be some of the most consistent projectiles we’ve ever measured.
One set of rounds was loaded with a carefully-weighed charge of unmodified kernels. Case to case charge weight was held to .05 grain (half a tenth uniformity). Then we prepared a second batch of cartridges with uniformed kernels, using the exact same charge weight, also held to .05 grain (half a tenth) tolerances. We took these rounds to the range, and did a “round-robin” test at 800 yards, shooting one of each type in sequence (i.e. one uniformed on right, then one non-uniformed on left) until we had two 10-round groups. The test was done with a rail gun fitted with a 1:8″ twist, 28″ Krieger 0.236″ land barrel. The uniformed-kernel ammo was shot at the right diamond, while the non-uniformed rounds were shot at the left diamond. Conditions were good, so we simply “held center” on every shot. No attempt was made to correct for wind as our primary concern was vertical dispersion.
Ammo with Uniformed Kernels Shows Significantly Less Vertical Dispersion at Long Range
As you can see, the uniformed-kernel ammo out-performed the non-uniformed ammo. The difference is quite clear. The rounds with non-uniformed kernels (on the left) produced a 10-shot group with roughly 3.0 inches of vertical dispersion. On the right, our ammo with uniformed kernels produced a group with 9 of 10 shots showing roughly 1.75 inches of vertical dispersion (we did have one high flier among the uniformed-kernel rounds). Additionally, we had a lower 10-shot ES and SD with the uniformed-kernel ammo. We repeated this test two more times and the results were similar. The targets speak for themselves. If you are looking for ultimate long-range accuracy, powder kernel uniforming is a “new frontier” you may wish to explore. With all other factors held constant, we were able to reduce vertical dispersion by more than an inch at 800 yards by drill-uniforming our NitroChemie powder. That’s huge in the long-range game.
Yes, the kernel-uniforming process is incredibly time-consuming and tedious, and a set of micro-drills is not cheap. We also freely acknowledge that the process may be much less productive with narrow-kernel propellants that are hard to drill. (Also EuroChemie powders are preferred because the burn rate controlling compounds are impregnated throughout the entire kernel — not just the outside.) But the potential for significant accuracy gains is there. We proved that.
Is it worth the huge investment of time to drill your powder kernels? That’s a question each reader must ask himself. But if you know the competitor on the next bench over has uniformed his kernels, can you afford not to do the same? Sometimes the extra effort is worth it, just for the peace of mind you get knowing you’ve done everything possible to achieve “ultimate accuracy”.

Here’s a tip that can help you score higher at matches and get more predictable results when weighing loads with an electronic scale. Kelly Bachand, a top prone shooter and electrical engineering major at the Univ. of Washington, tells us that all digital scales can drift. Therefore Kelly recommends re-calibrating electronic scales often. In addition — and this is key — Kelly recommends that you shoot the ammo in the exact order in which it was loaded. Arrange your loaded ammo in a box in the order of loading and shoot it first-loaded to last-loaded. (Or, if you prefer, shoot it last-loaded to first-loaded.) The important thing is to maintain the order and not mix everything up. That way, if your scale drifts, the effect of drift on charge weight will be incremental from one loaded round to the next, so point of impact change should be negligible. Conversely, if you shoot your last-loaded round right after your first-loaded round, the effect of scale drift is at its maximum, so powder charge varience is maximized. And that can produce a different point of impact (POI) on the target.
Tips on Loading with Electronic Scales by Kelly Bachand
If you use a digital scale to measure powder charges, recalibrate the scale often. I like to do this about every 25 rounds or so. Additionally, most electronic scales rely on eddy currents for their precision. Eddy currents are easily disrupted by static electricity so keep a cloth or ground strap nearby to remove any static currents should the scale start acting up; I usually just use a fabric softener sheet that has gone through the dryer once.
Shoot Ammo in Order of Loading
I shoot my rounds in the same order or reverse order as I load them. If the charge weight varies due to scale drift during use, the difference will be gradual if I shoot in the same order as production (or reverse order). I should be able to adjust for the slight varience in charge weight without having any wildly high or low shots (see the charts below for a graphical demonstration). I usually load my ammunition just 100 rounds at a time. Give yourself plenty of time and remember that you will make your best ammunition when you are fully awake and alert.
This graph demonstrates the effect a .01% (that’s 1/100th of 1 percent) difference in scale measurement would have over the course of 100 rounds assuming the desired load is somewhere between 46 and 47 grains. The final round made would have almost 1% less (or more) powder than the first, that’s almost an 0.5 grain difference from the first. If shot back to back, these rounds will invariably have different points of impact on the target.
This graph demonstrates the same .01% difference in scale measurement but this time with a recalibration every 25 rounds. By recalibrating the scale every 25 rounds the furthest a weighed charge ever gets from the original is less than 0.25%. Again if the charge being weighed is between 46 and 47 grains then the 26th round made would vary from the 1st by .12 grains. Even that small difference would likely show on target.
Either way it is important to note that if the bullets are shot in the same (or reverse) order as they are made, the biggest difference from bullet to bullet in this example is less than .01 grains.

At SHOT Show, we had the chance to meet with German software engineer Hartmut Broemel, creator of QuickLOAD software. This software program, while not a substitute for conventional load manuals, allows shooters to evaluate a wide range of powders and bullets, comparing potential loads on the basis of predicted pressures, velocities, load density and projectile in-barrel time.
We took the opportunity, in the video below, to explain some of the fine points of QuickLOAD for our members. QuickLOAD, sold by Neconos.com, helps reloaders understand how changing variables can affect pressures and velocities. It can predict the effect of changes in ambient temperature, bullet seating depth, and barrel length.
In the video below we explain how to adjust the program for true case capacity, bullet seating into the lands, and other important factors. If you are a new QuickLOAD user, or are contemplating buying the $152.95 program, you should watch the video. The program isn’t perfect, but it can accelerate the load development process, and it can save you money by narrowing down the list of appropriate powders for your cartridge.
No other product currently available to serious reloaders offers as much predictive power as QuickLOAD, and you’ll find your money well spent just for the vast collection of data on bullets and cartridges. With a couple mouse-clicks you can instantly get the specifications of hundreds of bullets and cartridges. Likewise, in a matter of seconds, you can compare load density for a half-dozen powders, or compare the projected velocities of one cartridge versus another.
