Take a close look at these illustrations which show the key differences between the four main powder types: extruded (stick) powder, ball (spherical) powder, flattened ball powder, and flake powder.
Burn Rate Basics
Widener’s Guide to Smokeless Powders also has a useful discussion of Burn Rate (a confusing topic for many hand-loaders). Wideners explains: “While a gun powder explosion in the cartridge seems instantaneous, if you slow it down you will actually find that each powder has a different ‘burn rate’, or speed at which it ignites.” This video shows powders with two very different burn rates. Watch closely.
Different burn rates suit different cartridge types notes Widener’s: “In general a fast-burning powder is used for light bullets and low-speed pistols and shotguns. Medium-rate powders are used for magnum pistols, while high-velocity, large bore rifle cartridges will need slow powders[.]
It should be noted that burn rate does not have a standardized unit of measurement. In fact, burn rate is really only discussed in comparison to other powders; there is no universal yardstick. Specifics will change by cartridge and bullet types[.]”

Lapua, maker of premium brass, bullets, and loaded ammo, has released a new, state-of-the-art Ballistics program that runs on smartphones and mobile devices. The all-new Lapua Ballistics Mobile App is the first mobile ballistics app utilizing the 6DOF calculation model. 6DOF refers to “Six Degrees of Freedom”, referring to the multiple variables the software calculates. As explained below, a 6DOF solver can account for 3 components of movement PLUS 3 components of rotation. Of course, as with other ballistics software, the Lapua Mobile App looks at Bullet BC, velocity, and cross-wind effects. This software can also account for subtle, extreme long range factors such as the Coriolis Effect.
Notably, the new Lapua Ballistics App includes a library of up-to-date bullet profiles based on extensive field tests with Doppler Radar. Having an ultra-sophisticated 6DOF solver combined with Doppler Radar data makes the Lapua Mobile App one of the most accurate ballistics Apps on the market. Lapua Ballistics offers the latest, Doppler-proven Lapua cartridge and bullet data for you to combine with your firearm and local weather information. The App also includes the option to define custom bullets.
The Lapua Ballistics App is available for Android and iOS smart phones and mobile devices free of charge. For more info, visit www.lapua.com/lapuaballisticsapp.
6DOF, the most accurate calculation method. Lapua cartridge / bullet information. Distance, wind speed and angle. outputs numerical, reticle, table and graph views, metric and imperial values.

The Nammo Group, parent of Lapua and Vihtavuori, has announced the acquisition of Berger Bullets, one of the USA’s leading bullet makers. With Berger Bullets joining the Nammo Group, this teams America’s ultra-premium bullet-maker with what is arguably the world’s most respected cartridge brass and ammunition-maker. This is huge news. For competition shooters this may be a “marriage made in heaven”. Many top shooters, including champions like Bryan Litz and John Whidden, are already shooting Berger bullets in Lapua brass. This merger will make it easier for the two companies (Berger and Lapua) to optimize the performance of factory ammo, as well as to optimize brass for use with Berger match projectiles.
A spokesman for Lapua said that Lapua will continue to make bullets in Europe while Berger will conduct its regular operations in the USA: “Lapua will still make bullets, and it will be ‘business as usual’ for Berger at this time. There are no plans to change production sites to consolidate product lines. Berger will continue to operate as an independent business, just under the Nammo umbrella.” NOTE: This acquisition will be subject to regulatory approvals by U.S. governmental authorities.
On firearm industry analyst believes this merger is a “win-win” for both Berger and Nammo: “This will help Berger export more product to the European market while it will give Nammo a stronger connection to the huge U.S. firearms market, expanding Nammo’s North American customer base”. Nammo president/CEO Morten Brandtzæg concurred, stating: “Having Berger Bullets on board is the perfect match for Nammo. Their products, which are complementary to our other premium brands, will strengthen our group’s strategic position in the U.S. commercial ammunition market.” This acquistion WILL include Berger’s ABM Ammunition and J-4 Jackets product lines.
Here is the press release issued by the Nammo Group, which is headquartered in Norway and has 2,100 employees in 12 countries:
I would like to emphasize a couple of things before you read on. The [acquisition of Berger Bullets by Nammo] CHANGES NOTHING. Production will remain in the same facility, by the same people, to the same quality. Berger Bullets will remain the highest-quality bullets on the market. What this merger does, is it gives these companies [the opportunity] to work together, to provide the highest-quality ammunition.
Lapua is well known for its high-quality brass, VihtaVuori makes high-quality powder, and Berger makes high-quality bullets. When you put the three together, you have the possibility of unmatched, premium … factory ammunition. To be clear, this will not affect the quality or way that Berger bullets are produced.
Q & A about Berger Bullets Joining Nammo Group
Q. What are Nammo’s plans concerning Berger Bullets?
A. Nammo plans on operating Berger Bullets as a stand-alone brand with support from the Nammo Group in a number of areas. First, they would like to help Berger improve the availability of many of their bullets that are in high demand.
Q. Are you going to eliminate any specific bullets? In other words, do they need to stock up!
A. We have no immediate plans to discontinue any of our bullets. We will continue as a part of our normal business practice to discontinue bullets that have been replaced by a superior product or those that do not have a demand sufficient to warrant allocating time in our production schedule. This is just what we have always done as part of our process.
Q. Is Bryan Litz still going to be the ballistician for Berger Bullets?
A. Yes. Bryan is an important part of the Berger Bullet team and our plans definitely include keeping Bryan on as our lead ballistician.
Q. Is Eric Stecker going to remain in charge of Berger Bullets?
A. Eric Stecker will continue as President of Berger Bullets
Q. Are the same dealers going to carry Berger Bullets?
A. Yes, we have no plans to change the way we distribute Berger Bullets to the shooting community.
Q. Does this mean ABM Ammo will have direct access to components like powder and brass?

Here’s good news for short-range benchrest shooters. The two most popular powders for the 6PPC, Vihtavuori N133 and Accurate LT-32, are now in-stock at Powder Valley Inc. (PVI). In fact, Powder Valley even has the hard-to-find 8-lb jugs of N133 and LT-32.
For you 30BR score shooters, PVI has both Hodgdon H4198 and Accurate LT-30 in stock, the two most popular powders for the 30BR. A slightly faster-burning version of LT-32, LT-30 is a very promising powder for the 30 BR, while H4198 has traditionally been the “go-to” choice for the 100/200-yard score shooting game. PVI has 1-lb and 8-lb containers of both these ultra-accurate powders in stock now. Visit PowderValleyinc.com, and click on the “Powders” link in the Menu.

Is that target good enough? Yes that’s really five (5) shots. This amazing group was shot, in competition, with 6 PPC cartridges loaded with Accurate LT-32 powder. If you’d like to try out this powder in your rifle, Western Powders has released loading data for the LT series of powders. LT-32 is a good choice if you’re currently using propellants with burn rates similar to Vihtavuori N133 or Hodgdon Benchmark powders. (Caution: NEVER simply substitute loads powder for powder. Always start low and work up when trying a new powder). The other powder in Accurate’s LT series, LT-30, has a burn rate similar to Hodgdon H4198. LT-30 is a superb performer in the 30 BR cartridge. LT-30 also is a good choice for small varmint cartridges such as the 17 Rem Fireball.

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.

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.”

Powder Valley just announced it has received 120 4-lb kegs of Vihtavuori N320 powder. This stuff has been hard to find lately, so Powder Valley suggests: “Get em quick. They won’t last long!”
We know why N320 powder is in high demand (most vendors are sold out right now). This is a truly outstanding propellant for the .45 ACP. It is very accurate, burns clean, and it meters well from progressive presses. This Editor has tried a dozen different powders for my .45 ACPs and N320 is my top choice for 180-200gr bullets. Nothing was more accurate, and N320 burned cleaner (with fewer sparks and unburnt particles flying back) than WW 231 (which is also very accurate).

If you read our 2011 Super Shoot Report by James Mock, you’ll see that Vihtavuori N133 powder is the overwhelming choice of top short-range benchrest shooters for loading their 6PPCs. Other Vihtavuori powders, such as N135, N150, and N550 are also very popular for other match and hunting cartridges.
If you currently use a Vihtavuori (VV) powder, or you plan to try a Vihtavuori powder in the near future, visit www.Lapua.com soon. Load info on Lapua’s Vihtavuori Reloading Data Page has been updated (or added) for the following calibers: .222 Remington, .223 Remington, .223 WSSM (new caliber data), .22-250 Remington, 6.5 Grendel, 6.5×47 Lapua, and 7.62x53R. In the updated tables, you’ll find VV powder recipes for a wide variety of bullets from Hornady, Lapua, Nosler, Sierra, Speer and other bullet-makers.
Though these recipes are fairly conservative, always start low and work up gradually when using a new powder for the first time. Likewise, you should back off your load if you change ANY component or if you have fitted a new barrel to your rifle.
Vihtavuori N100 Series
The N100 series powders are single-base powders used mainly in rifle calibers. There are ten N100 series powders with different burning rates and suitability from the .17 Remington up to the .458 Winchester Magnum and two special powders for .50 BMG.
The N500 series powders are impregnated extruded rifle powders with Nitroglycerol added as extra energy component. If higher loading densities and more energy are needed, N500 series powders are competent alternatives for the N100 series powders. N500 series High Energy powders are available in five different burning rates.
