Join the Fun — August is National Shooting Sports Month

August 2018 National Shooting Shoot sports month celebration

Well folks, today is the first day of August, National Shooting Sports Month (NSSM). To help grow the shooting sports, the National Shooting Sports Foundation (NSSF) asks you to bring a new shooter to the range this month. That’s a good mission — adding to the ranks of shooters is the best way to preserve our Second Amendment rights.

August 2018 National Shooting Shoot sports month celebration

This coast-to-coast celebration spotlights the fun and enjoyment of target shooting. Newcomers can take their first shots, and experienced shooters can invite someone new to the range or help an erstwhile shooter rediscover the fun of target shooting. This month-long event involves all the shooting sports — rifle, pistol, and shotgun.

The NSSF has an online database of NSSM shooting events scheduled for August. Right now there are over 1400 August events in the database — matches, clinics, training sessions, special sales — and much more. The NSSF is even providing a dozen FREE Downloadable Targets.

In addition there are numerous online promotions. With these you can save 5-20% off the price of guns, ammo, optics, holsters, accessories and other gear. Participating companies including Savage, Kimber, SIG Sauer, Sportsman’s Guide, and Insight Tactical. CLICK HERE for August Online Discount Programs.

What Shooters Can Do to Promote National Shooting Sports Month:
The NSSF says: “As shooters, you serve a critical role in the continued growth of gun ownership and shooting sports participation. We urge you to join us this August for National Shooting Sports Month.” There are a variety of ways you can help this August:

— Introduce a family member, friend, or group of friends to the shooting sports by taking them to a local range that’s hosting an event.

— Spread the word to family/friends and encourage them to get out to the range in August.

— Encourage the ranges and retailers near you to host an event this August and add them to the official events calendar at www.ShootingSportsMonth.org.

“With so much going on in people’s lives today, the shooting sports offer an opportunity to tune out distractions, learn a new skill, socialize and share their experiences,” said NSSF President and CEO Steve Sanetti. “It’s important to remember to pass on our traditions and to reflect on our unique freedoms that make participating in them possible.”

Ballistics TIP: How Altitude and Air Pressure Affect Bullet Flight

Trajectory of Bullet fired at Sea Level

Trajectory of Bullet fired at 20,000 feet

You can do your own experimental calculations using JBM Online Ballistics (free to use). Here is an extreme example, with two printouts (generated with Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.

Suunto AltimeterOne of our readers asked “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, the bullet behaves as if it has a higher ballistic coefficient.

Forum member Milanuk explains that the key factor is not altitude, but rather air pressure. Milanuk writes:

“In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ ASL or less. I’ll need about 29-30 MOA to get from 100 yard to 1000 yards with a Berger 155gr VLD @ 2960fps. By contrast, in Raton, NM, located at 6600′ ASL, I’ll only need about 24-25 MOA to do the same. That’s a significant difference.

Note that it is the barometric pressure that really matters, not simply the nominal altitude. The barometric pressure will indicate the reduced pressure from a higher altitude, but it will also show you the pressure changes as a front moves in, etc. which can play havoc w/ your calculated come-ups. Most altimeters are simply barometers that read in feet instead of inches of mercury.”

As Milanuk states, it is NOT altitude per se, but the LOCAL barometric pressure (sometimes called “station pressure”) that is key. The two atmospheric conditions that most effect bullet flight are air temperature, and barometric pressure. Normally, humidity has a negligible effect.

It’s important to remember that the barometric pressure reported on the radio (or internet) may be stated as a sea level equivalency. So in Denver (at 6,000 feet amsl), if the local pressure is 24″, the radio will report the barometric pressure to be 30″. If you do high altitude shooting at long range, bring along a Kestrel, or remember to mentally correct the radio station’s pressure, by 1″ per 1,000 feet.”

If you want to learn more about all aspects of External Ballistics, ExteriorBallistics.com provides a variety of useful resources. In particular, on that site, Section 3.1 of the Sierra Manual is reprinted, covering Effects of Altitude and Atmospheric Pressure on bullet flight.
