Vihtavuori Explains Powder Grain Shapes

POWDER GRAIN SHAPES — What You Need to Know

The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).

All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.

Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.

Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.

The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.

The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.

So how does the shape affect pressure and muzzle velocity? In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.

Hodgdon Releases New Winchester WinClean 244 Pistol Powder

Winchester Winclean pistol powder Smith Wesson 637 .38 Special .357 hand loading

Hodgdon has just introduced a versatile new Winchester-brand pistol powder with a clean formulation. WinClean 244 is a modern, Winchester-branded propellant “ideally suited to .38 Special, .45 Auto, and 9mm standard loads.” That means WinClean 244 is designed for moderate pressure target loads. That’s good news for hand-loaders who enjoy target shooting with these popular cartridges.

Hodgdon, which markets Winchester powders, says that new WinClean 244 is consistent, and clean burning with a low flash: “The WinClean formulation reduces copper fouling and residue, extending accuracy for longer shooting periods.” It will be interesting to see if this is noticeably cleaner-burning than other popular powders. In pistol barrels we are actually less concerned with copper fouling than with general “sootiness” and carbon.

With its clean-burning qualities, “shooters are really going to like loading handgun cartridges with this powder” said Tim Vaitekunas, vice president of product development at Hodgdon. WinClean 244 powder, in 1-, 4- and 8-pound canisters, should be in stores in January 2018. Load Data is now available right now on the Hodgdon Reloading Data Center.

This Editor used to compete in Action Pistol matches, so I’ve loaded thousands of rounds of pistol ammunition using a wide variety of pistol propellants. I tend to favor Vihtavuori N310/N320 for .45 ACP, and Alliant powders for 9mm Luger, but it will be interesting to see how WinClean 244 works for these chamberings. Many powders work well for .38 Special loads, but new 244’s low flash could be an advantage there too.

Pistol Showcase — Candidates for WinClean 244

Winchester Winclean pistol powder Smith Wesson 637 .38 Special .357 hand loading

The Sig P210 SuperTarget is a modern 9mm Luger pistol with exceptional accuracy and one of the best out-of-the-box triggers you’ll ever try. Winchester WinClean 244 is suitable for a variety of bullet weights in the 9x19mm (9mm Luger) cartridge.

Winchester Winclean pistol powder Smith Wesson 637 .38 Special .357 hand loading

The 8-shot Smith & Wesson Model 627 Pro is an exceptional revolver that balances well and can shoot 1″ groups at 25 yards with tuned handloads. On this particular Model 627, featured on YouTube, the owner added a Hogue Pau Ferro wood grip, Hogue Extended Cylinder Release, and Wilson Combat trigger spring kit. In this kind of wheelgun, you can shoot moderate .38 Special target rounds loaded with new WinClean 244 powder.

Remington RP9 9mm pistol handgun CDNN $249.99 with Rebate

Here’s a killer deal on a modern, full-size, 9mm pistol. The striker-fired Remington RP9 is similar to Smith & Wesson’s popular M&P9, but we prefer the Remington’s grip ergonomics. The RP9 comes with three (3) grip inserts and two (2) 18-round magazines. CDNN’s retail price is $299.99, but this pistol qualifies for a $50 mail-in Rebate from Remington. That knocks your net cost down to $249.99. That’s less than half the price of a Glock 17 or Glock 19. It’s also considerably less expensive than competitive full-size 9mm pistols from Ruger or Smith & Wesson. Put the money you save into ammo and a good holster. NOTE: Remington $50 Rebate is good through July 30, 2017.

The RCBS Rock Chucker remains a classic — a big, strong, versatile press that can handle most reloading chores with ease. And now you can get a genuine Rock Chucker Supreme for $126.99 — a very good deal. The Rock Chucker offers plenty of leverage for case-sizing and the “O” is tall enough for long cartridges. The Rock Chucker has a very strong base and should last a lifetime. We’re not fans of the Rock Chucker’s priming system but most serious reloaders use a separate priming tool.

9. MidwayUSA — Packable Shooting Mat, $19.99

MidwayUSA roll packable shooting mat light weight mat

Here’s a heck of a deal on a good light-weight shooting mat. MidwayUSA has slashed the price on its Packable Shooting Mat.

This Packable Mat has some nice features, such as 12″ front flap, elbow pads, 0.15″ thick padding, and six staking grommets. It’s easy to transport, rolling up to a 9″ x 4.5″ package, secured with a heavy strap. If you need a low-cost shooting mat, check this out. Weighing just 1.5 pounds, this is a good, light-weight mat to keep in a vehicle or use on a “walk-around” varmint hunt.

10. Amazon — EC Technology 22400mAh Battery Pack, $32.99

USB Battery pack EC Techonolgies Amazon 22400 mAh

This EC Technology 22400 mAh Power Pack is what AccurateShooter’s Editor uses to run a LabRadar Chronograph and recharge smartphones and his iPad on the road.

For the .45 ACP — Try Vihtavuori N320 Pistol Powder

VV N320 for .45 ACP

VV N320 for .45 ACPMan 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 powder choices include: AA #5 (Accurate Powder); Bullseye (Alliant); Clays, HP-38, and Titegroup (Hodgdon); VV N310, N320, N340 (Vihtavuori); and WW 231 and WST (Winchester). We’ve tried these powders in a variety of .45 ACP handguns. When we consider 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/Cons of Different Powders for .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.

Vihtavuori N320

  • 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.

Widener’s Guide to Smokeless Powders

Widener's Reloading Smokeless Powder propellant Guide

Widener’s Reloading & Shooting Supply recently published a helpful introduction to reloading powders. Widener’s online Guide to Smokeless Powders shows the various types of powders, and explains how the differences in powder kernel/flake size and shape, and burn rate affect performance. We recommend you visit Widener’s website and read the Powder Guide in full.

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[.]”

Breaking News: Berger Bullets Joins Nammo Group

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:

More Details on Berger Bullets Joining Nammo Group

On the heels of the announcement that Berger Bullets will join the Nammo group, the following information was posted on the Long Range Hunting Forum by Doc Beech of Applied Ballistics:

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?
A. Yes.

Load Data for Accurate LT-30 and LT-32 Powders

Western Powders LT-32 LT-30 accurate powder

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.

Nammo Announces Acquisition of Vihtavuori

Nammo Lapua acquires VihtavuoriIt’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.
