Here Todd Jarrett nails three steel targets and a pop-up orange clay bird. Watch full video below.

If you are a fan of 3-Gun competition, tune in to Shooting USA this week. The latest episode, which airs Wednesday October 4, features the 2018 USPSA Multi-Gun Nationals in Boulder City, Nevada. You can see many of the nation’s top 3-Gun shooters attacking some very challenging stages with pistols, rifles, and shotguns. CLICK HERE for TV Schedule.

Multi-gun competition has evolved considerably since it started 30 years ago. The firearms are more sophisticated, the optics are better, and the stage times are much faster. Still, the challenge remains the same: How fast can you shoot multiple targets, with the score determined by speed and accuracy? For the best in the sport, the answer is very fast indeed, but Match Director Pete Rinsing has a few tricks up his sleeve to challenge competitors on never-before-seen courses of fire at the USPSA Multi-Gun Nationals held in April 2017.

Todd Jarrett highlights from 2017 USPSA Multi-Gun Nationals. Check out 300-yard prone rifle at 00:30, and blazing rifle-pistol-shotgun transitions at 00:50:

Most people compete in the Tactical Division, including 8-time Champion, Daniel Horner. Horner rose to the rank of Sergeant First Class with the USAMU. Now a civilian, Horner currently shoots with Team SIG. Competitors in the Tactical division are not allowed a bipod, so many competitors utilize structures on the stage to stabilize their long gun. Regardless of division, the USPSA Multi-Gun Nationals is a true test of manipulating three different weapons, under pressure, on run-and-gun courses of fire. And the pressure is definitely on when a National Championship is on the line.

Tuning Barrels for Enhanced Precision and Accuracy

Anschutz Tuner

When a shot is fired through it, a barrel will exhibit harmonics. Tuning these harmonics (the “waves” that propagate through the barrel) can alter point of impact and, if you’re lucky, reduce group size. Barrel tuners have been used successfully in rimfire benchrest for many years (see photo above). While there are competing theories as to how and why barrel tuners work on rimfire rifles, there is no question that the accuracy of some rimfire barrels can be improved with the addition of a tuner. By changing the position of weights at the end of the barrel, we’ve seen shooters shrink their average group size as well as adjust the “sweet spot” for different lots of rimfire ammo. On the other hand, tuners can be the source of great frustration; some installations may yield little or no benefit. A shooter may have to experiment with a variety of different tuner designs (and weights) to find the optimal configuration.

In centerfire benchrest competition, the vast majority of competitors do not use tuners, though a few short-range shooters such as Gene Bukys and Jackie Schmidt have enjoyed considerable success. Gene has won major championships with tuned rifles. In 2011 Gene won both the Super Shoot and World Benchrest Championship (WBC), and Gene recently set a new NBRSA Sporter Class Grand Agg Record.

Centerfire benchrest guns typically employ shorter barrels with a much fatter contour (larger diameter) than rimfire rifles. Because centerfire rounds produce much higher pressures and velocities that a 22LR, a centerfire barrel also exhibits much different vibration characteristics than a typical rimfire barrel. Nonetheless, there are pioneers working with centerfire tuners who believe that tuning may be the “next leap forward” in centerfire accuracy.

Shown below is a switch-barrel benchrest rifle built by Forum member Eddie W. of Texas. It features a dual-port Hall “M” action with a ShadeTree Engineering Tuner crafted by Butch Lambert. The gun is designed to take both a 6PPC barrel for group shooting and a 30BR barrel for score shooting. The gun was barreled by Wayne Shaw, and Eddie did the stock work himself. Eddie reports: “It is a very accurate rifle.”

Will we see more tuners on centerfire rifles? Only time will tell. Some folks believe that, since one can easily adjust the loads shot by centerfire guns (by tinkering with the powder charge and seating depth), tuners have limited utility. On the other hand, tuner advocates such as Gene Beggs believe tuners can help keep your group sizes small even as conditions (temperature, humidity) change. Gene believes that, with an appropriate tuner, you can spend less time fiddling with the load specs (changing your powder charge) and instead “dial in” your sweet spot using the tuner.
