Sherri Gallagher Uses .260 Rem to Win National HP Championship
Following SGT Sherri Gallagher’s record-setting victory in the 2010 NRA High Power National Championship, many readers have asked what caliber (chambering) Sherri was shooting. Well, Sherri was shooting a .260 Remington at all yardages, as confirmed by SFC Emil Praslick, USAMU rifle coach. Runner-up Carl Bernosky was shooting a 6mm Hagar in an AR-platform rifle.
To capture her first High Power Championship, with a record 2396-161X score, Sheri used a Tubb 2000 bolt gun chambered in .260 Rem. According to Praslick: “[the rifle has] the same barrel as last year. I believe it has close to 2000 rounds on it.” To our surprise, Sherri’s ammo was loaded in relatively inexpensive Remington brass. Praslick explained: “We use Remington brass, Federal 210Ms, and Varget powder. For the 300/600 yard lines we use the Sierra 142gr bullet. Her 300RF load is around 2650 fps, the 600SF load approximately 2750 fps. At the 200 [yard line], we use a reduced recoil load using the Sierra 107gr MK.”
Accuracy Trumps Raw Velocity
Praslick noted that Sherri’s load, while not particularly fast, is ultra-accurate: “All these loads rely much more on accuracy than they do velocity. SGT Gallagher’s rifle has been tested repeatedly at 600 yards. It will easily shoot 3″ to 4″ groups all day long. This is evident by her X-count.” Praslick added: “I am a big believer in the .260 for High Power shooting. [It offers] easy load development, ballistic advantage, and long barrel life.”
.260 Rem Resources
To learn more about the .260 Rem, read Zak Smith’s article: 6.5mm Shootout: .260 Remington vs. 6.5×47 Lapua vs. 6.5 Creedmoor. Zak compares three popular 6.5mm cartridges, weighing the pros and cons of each. Zak himself shoots the Rem .260 loaded with 139gr Lapua Scenar bullets and Alliant Reloder 17.
Another great load for this cartridge is the 123gr Lapua Scenar pushed by Hodgdon H4350. That was the best overall performing load in this Editor’s .260 Rem. I was able to run the 123s at 2950 fps with great accuracy and extremely low ES and SD. Compare the 600-yard ballistics of the Scenar 123s at 2950 fps with Sherri’s 142gr SMKs launched at 2750 fps. You may be surprised. The 123s have less drop, and the 10 mph wind drift (at 600 yards) is very close: 23.9″ for the 123s vs. 22.8″ for the 142s.
