U.S.A. Palma Team Practices at Camp Perry

U.S. Palma Team Camp Perry Ohio World Championships

U.S. Palma Team Camp Perry Ohio World ChampionshipsThe Fullbore (Palma) World Championships will be held at Camp Perry, Ohio this summer. The American squad arrived a bit early — for a few days of team practice. Our friend Anette Wachter (aka 30 Cal Gal) is in Ohio with Team USA and she posted some photos on Facebook. Skies were gray, but that didn’t deter the American shooters who practiced their shooting under the watchful eyes of top wind coaches.

Take a look at the photo above. How many ace American shooters can you spot? Here’s one hint — pulling the black wheeled case is John Whidden, past U.S. Long-Range National Champion.

At right is the first bit of Team USA swag. Anette says there is more to come — team shirts and jackets were sized and ordered for all the U.S.A. shooters and coaches.

King of Two Miles Event in New Mexico

Long Range 2500 yards Whittington King of Two Miles

Long Range 2500 yards Whittington King of Two Miles1000 yards? Heck, for these KO2M guys, that’s just a warm-up — they plan to shoot out to 2500 yards and beyond. A new ultra-long-range event will be held this summer in New Mexico at the NRA Whittington Center. The King of Two Miles (KO2M) match will be held on July 1-2, 2015, right before the Fifty Caliber Shooters Assocation (FCSA) 1000-yard World Championships. If you like hurling big projectiles at very long ranges, Whittington is the place to be in July. The KO2M event is “wide-open” — any caliber is allowed and rifle size/weight is limited only by the shooter’s ability to lift the gun himself. Rifles will be shot prone with bipod.

Two Miles (Well Not Quite)
The name of the event is a bit of a misnomer, as the max range will be roughly 2500 yards. That’s WAY less than a full two miles (3520 yards). KO2M organizers do plan to go all the way out to two miles in the future, but they say their target and spotting technology isn’t up to that yet. Accordingly, the 2015 course of fire will include steel and electronic targets placed at known distances from 1000 to roughly 2500 yards. Next year, hopefully, the max range will be extended to over two miles, but, for now: “Current optical systems do not allow that.”

"How Do Bullets Fly?" — Great Online Resource

Bullet External Ballistics
“The overturning moment MW tends to rotate the bullet about an axis, which goes through the CG (center of gravity) and which is perpendicular to the plane of drag….

Ruprecht Nennstiel, a forensic ballistics expert from Wiesbaden, Germany, has authored a great resource about bullet behavior in flight. Nennstiel’s comprehensive article, How Do Bullets Fly, explains all the forces which affect bullet flight including gravity, wind, gyroscopic effects, aerodynamic drag, and lift. Nennstiel even explains the rather arcane Magnus Force and Coriolis Effect which come into play at long ranges. Nennstiel’s remarkable resource contains many useful illustrations plus new experimental observations of bullets fired from small arms, both at short and at long ranges.

A convenient index is provided so you can study each particular force in sequence. Writing with clear, precise prose, Nennstiel explains each key factor that affects external ballistics. For starters, we all know that bullets spin when launched from a rifled barrel. But Nennstiel explains in greater detail how this spinning creates gyroscopic stability:
