+ONE — Help a New Shooter During Nat’l Shooting Sports Month

National Shooting Sports month nssf +one

national shooting sports month nssf+ONE Program to Encourage New Shooters
August is National Shooting Sports Month. As part of this effort, the NSSF encourages firearms owners to take one novice to the range this one. This +ONE Movement will help strengthen the ranks of shooters, which, in turn, can help protect our Second Amendment freedoms. The NSSF states: “If just one in three of America’s recreational shooters adds one new person to the shooting sports, we’ll secure a strong future for generations to come. So be the one. For all the thrills and excitement recreational shooting has given you, join the +ONE movement and invite someone to the range today. Share your experience on social media.”

As part of the +ONE Movement, the NSSF encourages all participants to practice gun safety and proper firearms handling and storage practices. This video covers basic gun safety procedures:

The NSSF has created a list of TEN Rules of Firearms Safety. While you’re at the shooting range or anywhere you handle a firearm, safety ALWAYS comes first. Here are the 10 Key Rules of Firearms Safety. NOTE: The first four rules are the most important.

Over 580 Entries at 2022 Camp Perry National Air Gun Events

Gary Anderson Competition Center

CMP Records 580+ Entries During 2022 National Air Gun Events at Camp Perry
The 2022 National Air Gun events, held this summer as part of the Civilian Marksmanship Program’s National Matches, welcomed over 580 air rifle and air pistol entries throughout July and August. The events were held at the Gary Anderson CMP Competition Center at Camp Perry, Ohio.

Gary Anderson Competition Center

This modern Gary Anderson Competition Center boasts a long row of indoor electronic targets, which can provide multiple target distances from fixed firing points.

Story based on Report by Ashley Dugan, CMP Staff Writer
The 2022 CMP National Air Gun events hosted both seasoned competitors and novice shooters. New to the schedule in 2022 was the 100 Shot Challenge, which consisted of 100 record shots. Winning the Air Pistol competition was Daniel Miller, of Mineola, Texas, with a score of 912-7X.

An AiR-15 Challenge Match was also on the schedule, featuring air guns that resemble AR-15 rifles and a simulated 100-yard target. Leading the event for the second consecutive year was SFC Brandon Green who finished with an impressive score of 396-19X. One of the nation’s greatest marksmen, the USAMU’s Brandon Green has won multiple High Power Rifle National Championships.

The CMP’s Bench League allows participants of any age to compete in a national-level event, even if he or she has never competed before. During the League, competitors fire air sporter, precision or AiR-15 rifles off a bench with sandbag support. Claiming the overall win in the 60 Shot Bench Air Rifle Match was Philip Edwards, of Marblehead, Ohio, with a score of 632.3.

A Center Shot contest, where participants who fire closest to target center have the chance to win money, also challenged air gun competitors in rifle and pistol categories. Leading the Rifle Center Shot contest was Scott Braun of Belvidere, Illinois, who fired the only 10.9 shot.

Reloading Powder Grain Shapes — What You Need to Know

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).

So how does powder grain 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.

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.
