Tests Show Lapua .260 Remington Brass is Very Uniform

If you have a rifle chambered in .260 Remington, you may be wondering if the Lapua .260 Brass is worth the money compared to domestic-made brass. Well, the answer is “yes” if you demand consistent weight and dimensional uniformity (including neckwall thickness).

Mike Harpster of Dead Center Sports took the time to weigh and measure Lapua .260 Rem brass. His test show this brass to be extremely uniform. Weight variance was less than one (1) grain in a 20-case sample. And case neckwall thickness was very consistent.

Report by Mike Harpster: Lapua .260 Rem Brass Test Results (with Comparisons)
I pulled twenty (20) pieces randomly from one Lapua box to do some measurements. I weighed them on my Mettler-Toledo digital lab scale and here are the individual weights of each case. Remarkably, the Lapua brass had less than one grain total weight variance among all 20 cases!

While checking the Lapua brass I remembered I had just received some Winchester brand .308 brass, so I thought it would be interesting to do a comparison between the two brands. I again pulled 20 cases at random from a bag of 50 and repeated the same measurements. The results are shown in the right half of the table below.

Weight Variance Lapua .260 Rem Brass vs. Winchester-Brand .308 Win Brass

LAPUA .260 Rem Brass Winchester .308 Win Brass
Average: 172.20 grains
ES: 0.94 grains
SD: 0.259
Average: 158.49 grains
ES: 2.64 grains
SD: 0.678

Winchester Brass Further Inspection
The flash holes on the majority of the Winchester brass were not round or centered and they had large burrs inside. The neck wall thickness was pretty consistent, varying only .0015″ (.0125″ – .014″). As you can see in the photo (right) many of the Winchester cases were badly dented while the Lapua brass showed very few minor dents. The annealing on the necks of the Lapua brass was clearly evident while the Winchester showed no signs of being annealed. [Editor’s note: Winchester tumble-polishes its brass before shipping — so you would not notice annealing coloration if annealing had been done.]

Lapua Brass Further Inspection
With sample Lapua .260 Rem cases, I also measured the neck wall thickness in four places with calipers, not the most accurate method but I feel confident that the thickness did not vary more than .001″ over the 20 cases (.0145-.0155). The inside diameter of the neck measured .260 which would give .004 of neck tension out of the box. I visually checked the flash holes and I did not find any flakes of brass or burrs inside, the holes were round and centered.

Summary — This Lapua Brass is Impressive
I have never done these measurements on any other brass so I don’t know how they compare, but I am very impressed with the overall quality of the Lapua .260 brass. If they prove to hold up to the repeated firings I get from my Lapua 6BR brass I believe .260 shooters will be very happy.

Sherri Gallagher Uses .260 Rem to Win National HP Championship

.260 Remington GallagherFollowing 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.”

.260 Remington GallagherAccuracy 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.

.260 Remington Gallagher

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.
