Sunday GunDay: Modern Air Rifles for 3-Position Competition

Three Position 3p air rifle airgun precisision competition CMP

Three Position 3p air rifle airgun precision competition CMPThree-Position Air Rifle (3PAR) shooting is the most popular and fastest-growing form of shooting sports competition for junior shooters (High School age and younger). The Civilian Marksmanship Program (CMP) conducts two primary Three-Position Air Rifle events. First, Precision Air Rifle is modeled after Olympic-style shooting and allows the use of specialized target rifles and equipment. Second, Sporter Air Rifle is designed for new competitors or those who desire to compete with a minimum of equipment and expense.

In both types of shooting, competitors fire at targets at a distance of 10 meters in three different positions, prone, standing and kneeling. Three-Position Air Rifle provides young competitors with competitive shooting sports opportunities that can be offered on a wide variety of easily accessible or easily constructed ranges, with equipment that is commonly available at affordable costs.

The CMP actively promotes Three-Position Air Rifle shooting as a premier youth marksmanship competition by providing low-cost equipment and pellets as well as training materials and competition activities. In addition, other air gun events for juniors and adults are hosted by CMP throughout the year. CMP facilities have Open Public Shooting evenings, and matches for air rifle and air pistol take place at the CMP Marksmanship Centers. CMP ranges are equipped with OpticScore Targets featuring technology by Kongsberg Target Systems.

Sporter Air Rifles

The largest and fastest-growing segment of junior shooting today, Three-Position Air Rifle Shooting, uses a class of target air rifles called Sporter Air Rifles. These Sporters now constitute a special class of junior shooting competition, and are used extensively in JROTC programs.

Sporter air rifles are characterized by their light weight (5-7 lbs.), low cost (from $180 to $600), basic target features (adjustable sights, adjustable length stocks, adjustable sling attachments) and good accuracy (rifles sold through this program must be capable of consistently shooting tens on the standard competition targets).

Giant Extruded Powder Sticks for Navy Cannons — Big Boomers

DuPont artillery naval powder cannon gun kernel propellant stick

Story by Boyd Allen
While many top competitive shooters trickle their stick powder charges to a kernel or two, that would be impractical when loading charges for giant naval guns. You may be surprised, but the shells fired by the U.S. Navy’s massive 14″ and 16″ naval guns were also propelled by stick-type extruded powders. You couldn’t trickle these ‘kernels’ though — a single stick or ‘grain’ can be over 2″ long.

DuPont artillery naval powder cannon gun kernel propellant stick
The U.S.S. Iowa fires her massive 16″ main battery. The U.S. Navy’s Iowa-class battleships carried nine huge 16-inch Mark 7 cannons in three turrets. The big naval guns were 50 calibers long, i.e. 50 times bore diameter, making the barrels 66.7 feet long from chamber to muzzle.

In connection with a Benchrest Central discussion that drifted to the subject of powders used in large naval guns, I heard from Joe McNeil, whose father was involved in manufacturing those very propellants as a DuPont employee. Joe writes:

“My Dad worked for the DuPont company for over 40 years. Every time the nation went to war he was assigned to the gun powder plants which DuPont ran for the government for $1.00 per year! His last assignment was at the Indiana Ordnance Plant in Jefferson, Indiana from 1952 through 1958. He had a display case made of all of the different powders made at the plant and left it to me. That’s why I have a grain of 16″ gun powder. He took me out to the Jefferson proving grounds once when they tested the powder in a 16″ gun. We watched from a half-mile away but it left a lasting impression when they fired that gun. They actually had a set of rings they fired through to test the performance of the powder and shell. This was a truly fond memory of my Dad and his work.”

Here are some pictures of the gun powder “grains” made during the Korean War at the Indiana Ordnance Works where Joe McNeil’s father worked.

Above is the display case with the different powders manufactured at the DuPont plant. They include: 37 MM/AA, 75MM Pack Howitzer, 50 Cal. 5010, 20 MM 4831, 30 Cal. 4895, 76 MM, 3″, 5″, 90 MM, 4.7″, 240MM, 8″, 280 MM, 175 MM, 155 MM Howitzer, 155 MM Gun M.P., 8″ Gun M.P., 12″, 14, 16″. There are different-sized ‘grains’ for specific rounds.

O-Rings on Sizing Die Lock Rings Can Reduce Run-out

reloading die O-ring
reloading die O-ring

Here’s an inexpensive procedure that can help you load straighter ammo, with slightly better measured concentricity (i.e. less run-out) on the case necks and bullets. Simply use a Rubber O-Ring on the underside of the die locking ring. This allows the die to self-align itself (slightly) to the case that is being sized. Without the O-Ring, if the flat surface on the top of your press is not perfectly square with the thread axis, your die can end up slightly off-angle. This happens when the bottom of the locking ring butts up tight against the top of the press. The O-Ring allows the die to float slightly, and that may, in turn, reduce the amount of run-out induced during case sizing.

Top prone shooter GSArizona, who sadly passed in 2022, tried this trick and said it works: “Go to your local hardware store and get a #17 O-Ring (that’s the designation at Ace Hardware, don’t know if its universal). Slip the O-Ring on the die and re-adjust the lock ring so that the O-Ring is slightly compressed when the die is at the correct height. Size and measure a few more cases. You will probably see a slight improvement in neck concentricity as the die can now float a bit as the case enters and leaves it. This isn’t going to be a dramatic improvement, but it’s a positive one.”

We want to stress that adding O-Rings to sizing dies may help some reloaders, but we don’t offer this as a panacea. Try it — if using the O-Ring reduces measured runout that’s great. If it doesn’t, you’ve only spent a few pennies to experiment.

reloading die O-ring

Lee Precision makes die lock rings with built-in O-Rings. Lee’s distinctive lock ring design allows the same kind of self-alignment, which is good. However, Lee lock rings don’t clamp in place on the die threads, so they can move when you insert or remove the dies — and that can throw off your die setting slightly. By using an O-Ring under a conventional die lock ring (that can be locked in place), you get the advantages of the Lee design, without the risk of the lock ring moving.
