N100 series Reloading Powders are single base powders used mainly in rifle calibres:

The series N100 powders are primarily rifle powders, with suitable speeds to optimize handloading from the tiny .17 Remington and .22 Hornet all the way to the monster bashing .458 Winchester Magnum. There are ten speeds in this series and they include:

N110 The fastest burning rifle powder from Vihtavuori. Similar to Hodgdon H110 and Winchester 296. N110 can be used in small rifle cases like .22 Hornet and .30 Carbine but also in magnum pistol and revolver cartridges like .357 S&W Magnum, .41 Magnum, .44 Magnum, .454 Casull and .500 S&W.

N120 Slower burning powder for small capacity rifle cases and for lighter bullets in many .22 caliber loads. N120 needs higher pressure than N110 in order to optimize burning. Burning rate is near to Accurate 1680, IMR 4198 and Reloder 7. N120 is suitable also for 7,62x39, .30-30 Winchester and .444 Marlin.

N130 This powder is used in many factory loaded calibre .22 and 6 mm PPC cartridges. Suitable also for lighter bullets in calibre .223 Remington and for straight-wall rifle cases like .45-70 Government and .458 Winchester Magnum. Burning rate is close to Hodgdon H322 and Accurate 2230.

N133 A choice of many bench rest and standard rifle shooters who are using 6 mm PPC. Used also in many loads of .222  Remington, .223 Remington and as well in other applications where a relatively fast burning powder is needed, like in .45-70 Government. Similarly burning powders are Norma 201, Hodgdon H335 and Vectan SP10.

N135 An excellent powder for .308 Winchester loads with bullet weight less than 10 grams (155 grains). It will fit applications similar to IMR4064, Hodgdon H4895 or Accurate 2520. Capability for various loads ranging from .17 Remington to .458 Winchester Magnum.

N140 A true multipurpose powder, which can usually be used in place of IMR4320, Reloder 15 or Hodgdon H380. Good choice also for .223 Remington, .22-250 Remington, .308 Winchester, .30-06 Spring field, 8x57 IS (8 mm Mauser) and .375 H&H Magnum.

N150 This powder burns a bit slower than N140 and works as well as Hodgdon H414 and Winchester 760. Typically used with heavier bullets in accuracy and hunting loads of cartridges with middle case volumes, like .308 Winchester, 6,5x55 SE and .30-06 Springfield.

N160 A slow burning powder for Magnum cartridges and calibres with large case volume and comparatively small bullet diameter. Burning speed of N160 is close to Reloder 19, Winchester WMR and the various 4831īs. For example some ideal applications are: .243 Winchester, 6,5-.284 Norma, 7 mm Weatherby Magnum, .300 Winchester Magnum, .338 Winchester Magnum and all the Winchester Short Magnums.

N165 A very slow burning powder for Magnum cartridges with heavy bullets. N165 offers performance equal to Norma MRP and Reloder 22. To be used with heavy bullets in calibres ranging from 6,5x55 SE all the way to .416 Rigby.

N170 The slowest burning N100 series rifle powder from Vihtavuori and one of the slowest canister re loading powders generally available from any manufacturer. It will fit applications similar to Hodgdon H1000 and Accurate 8700. Good performances in most of the belted Magnum cartridges like .300 Weatherby Magnum and suitable also for .300 Remington Ultra Magnum and .338 Lapua Magnum.

 

N500 series High Energy Reloading Powders • impregnated extruded rifle powders with Nitroglycerol added as extra energy component

Adding nitroglycerol to the traditional single base powder makes possible in addition to geometry and coating a third controlled variable of ballistic properties: energy content. Vihtavuori calls powders which have nitroglycerol added (maximum 25 %) high energy NC-powders, which form N500 series.

The composition of a typical high energy powder is as follows: • nitrocellulose • nitroglycerol

• coating agent • stabilizer

• flame reducing agent • wear reducing agent

Geometrically the powders in the N500 series are equal to the N100 series. Although these new powders have a higher energy content, they do not cause greater wear to the gun. This is because the surface of the powder has been treated with an agent designed to reduce barrel wear. N500 series powders work well at different temperatures, even better than the traditional N100 and N300 series. Temperature sensitivity naturally depends very much on the weapon and on the cartridge. The manufacturing technique employed permits a very high bulk density, which in turn makes it possible to use a bigger charge in a certain limited loading volume.

Vihtavuori High Energy powders are available in for burning rates:

N530 This is the fastest burning powder in the N500 series and its burning rate is close to Vihtavuori N135 and Hodgdon BL-C(2). Developed especially for the 5,56 mm NATO cartridges and it gives excellent performances in many .45-70 Government loads and also in .308 Winchester loads with bullet weight less than 10 grams (155 grains).

N540 Faster burning powder with a burning rate like with N140 and close to Hodgdon H414 and Winchester 760. To situations where more power is needed, especially for .223 Remington, .308 Winchester and .30-06 Springfield loads with heavier bullets.

N550 Burning rate is like with N150 and close to IMR 4350 and Reloder 19. Good choice for more powerful loads for 6,5x55 SE, .308 Winchester, .30-06 Springfield and for many others.

N560 Burning rate is between N160 and N165 and close to Norma MRP and Reloder 22. Powder especially for Magnum cartridges to get out the best power for example from .270 Winchester, 7 mm Remington Magnum, 7 mm Weatherby Magnum, .300 Winchester Magnum, .300 Weatherby Magnum and .338 Lapua Magnum.

N570 This is the newest member of the N500 series powders and also the slowest burning. The burning rate of N570 is near to N170 and it is faster burning than 24N41. The characteristics of this high energy powder with large grain size bring out the best in most of the large volume cases like for example in 6,5-.284 Norma, .300 Winchester Magnum, .300 Remington Ultra Magnum, .338 Lapua Magnum and .30-378 Weatherby Magnum.

 .50 BMG there are two special Vihtavuori reloading powders available: 24N41 and 20N29. They are, like N100 series, single base surface treated powders. Their burning rate is slower and grain size larger than that of the N100 series rifle reloading powders. The renewed relative burning rate of the 24N41 is 39 and that of the 20N29 respectively 36, when N110 is given the index 100, and therefore 24N41 is slightly faster burning than 20N29. There is reloading data available also for some other magnum rifle calibres with these powders and 20N29 has gained reputation also when used eg. in .300 Lapua Magnum and in .30-378 Weatherby Magnum.

 

N300 series Reloading Powders are single base porous powders for handguns.

Handgun powders include five N300 series propellants, three special propellants and one propellant applicated especially for Cowboy Action Shooting:

N310 Very fast burning and competitive with Alliant Bullseye, Hodgdon HP38 and Vectan Ba 10. It has applications in a very wide range from .32 S&W Long Wadcutter up to .45 ACP.

N320 A comparatively fast burning multipurpose handgun powder with burning rate about the same as Winchester 231 or Alliant Red Dot. Currently available reloading data for 9 mm Luger, .38 Super Auto, .38 Special, .357 Magnum, .40 S&W, .44 S&W Special, .44 Remington Magnum, .45 ACP and .45 Colt.

Tin Star (N32C) Special powder developed for Cowboy Action Shooters shooting lead bullets with revolvers and single-action rifles. It has low bulk density (less free space in the case) and it burns very clean without residues with a burning rate between N320 and N330. Reloading data is currently available for .38 Special and .44 Magnum.

N330 Burning rate is a bit slower than with N320 and corresponding to Alliant Unique and Vectan Ba 9. Especially designed for 9 mm Luger but also suitable for .38 Special, .40 S&W, .44 S&W Special and .45 (Long) Colt.

N340 An excellent multipurpose handgun powder with burning rate generally about like Accurate No.5 or Alliant Herco. Wide application area covers the following handgun cartridges: 9 mm Luger, 9x21 mm, .357 SIG, .38 Super Auto, .38 Special, .357 Magnum, .40 S&W, 10 mm AUTO, .44 S&W Special, .44 Remington Magnum, .45 ACP and .45 Colt.

N350 This is the slowest burning N300 series handgun powder, which can usually be used instead of Accurate No.7, IMR Hi-Skor 800-X and Alliant Blue Dot. Appropriate choice for many powerful handgun loads, for example in calibres 9 mm Luger, 10 mm AUTO and .45 ACP.

3N37 Originally developed for .22 rimfire cartridges but has proven to be very versatile and desirable within all competitive handgun shooting disciplines. The burning speed of this small grain powder is near to N350 and Vectan A0. Reloading data available for all popular handgun cartridges.

3N38 This specially designed powder for competitive handgun shooting is recommended for high velocity loads of 9 mm Luger, .38 Super Auto and .40 S&W with moderate bullet weight. Burning rate is corresponding to Vectan SP 2.

N105 Super Magnum Slow burning handgun powder filling the gap between N350 and N110. Especially developed for handgun cartridges with heavy bullets and/or large case volume. Reloading data is currently available for the following cartridges: 9x21 mm, .38 Super Auto, .357 Magnum, 357 Remington Maximum, .40 S&W, 10 mm AUTO, .41 Remington Magnum, .44 Remington Magnum, .45 Colt, .45 Winchester Magnum and .454 Casull.
