Vihtavuori N540 Smokeless Gun Powder

Clear Product Overview

Vihtavuori N540 Smokeless Gun Powder is a mid-rate, high-energy rifle propellant. Manufacturer Vihtavuori designed it specifically for medium-capacity rifle cartridges where increased velocity and flat trajectories are essential.

First, as part of Vihtavuori’s N500 high-energy series, nitroglycerin is added to its porous single-base core during manufacturing. Consequently, it delivers significantly higher muzzle velocities than standard single-base powders of similar burn rates without causing unsafe chamber pressure spikes. In addition, its medium burn rate makes it a versatile performer across mid-sized rifle cases. As a result, it is a top choice for target marksmen and hunters loading .308 Winchester, .223 Remington with heavy projectiles, 6.5 Creedmoor, .243 Winchester, and .30-06 Springfield. Furthermore, its clean-burning tubular grains meter consistently through reloading equipment. Therefore, it provides match-grade precision and maximum downrange performance.

Real-World Use Information

Competitive shooters and long-range hunters select Vihtavuori N540 when they want to squeeze extra speed out of medium rifle calibers while retaining match-grade group sizes. Consequently, it allows handloaders to drive heavy-for-caliber target and hunting bullets flatter and farther.

Additionally, the advanced chemical coating provides exceptional thermal stability across changing temperature conditions. Therefore, your point of impact remains consistent whether shooting during cold morning hunts or warm summer range days. Furthermore, its clean-burning characteristics reduce throat erosion and minimize carbon fouling during extended strings of fire.

Compatibility & Requirements

• Application Use: Performs best in medium-capacity rifle cartridges firing medium-to-heavy bullet weights.

• Load Data: Always consult official Vihtavuori load data manuals before charging brass cases.

• Storage: Keep this powder in its original sealed container in a cool, dry area away from direct heat sources.

Pros & Limitations

Pros:

• Enhanced Muzzle Velocity: Nitroglycerin impregnation yields higher speeds than standard single-base propellants.

• Versatile Application Range: Excellent performance across popular calibers from .223 Rem up to .30-06 Springfield.

• Temperature Stability: Engineered to maintain stable pressures and velocities across changing weather conditions.

• Uniform Metering: Smooth tubular grains pass reliably through powder measures for consistent charge weights.

Limitations:

• Not For Large Magnum Cases: Burn rate is too fast for large-capacity magnum cartridges like .300 Win Mag or 7mm Rem Mag.

• Higher Flame Temperature: High-energy double-base chemistry generates higher flame temperatures than single-base N100 series powders.

Frequently Asked Questions (FAQs)

Q: What is the difference between Vihtavuori N140 and N540?

A: While both share a similar burn rate, N540 is a high-energy powder containing nitroglycerin. Consequently, N540 yields higher muzzle velocities than the single-base N140.

Q: Is Vihtavuori N540 good for .308 Winchester?

A: Yes! N540 is an exceptional powder choice for .308 Winchester, especially when loading medium-to-heavy bullet weights for long-range match or hunting use.

Q: Does Vihtavuori N540 meter well?

A: Yes. The symmetrical tubular grains are manufactured to small, uniform dimensions, allowing them to meter smoothly through volumetric powder drops.
