6.5×47 Lapua Factory Ammo Field Test

Thanks to Adam Braverman of Nammo Lapua, Zak Smith had a chance to test out the new Lapua 6.5×47 123gr factory ammo recently in his Accuracy Int’l tactical rifle. Zak reports: “Accuracy was excellent–the ammo shot as tight as I could hold in the windy conditions. This ammo is half-MOA or better, easy. When I did my job, all shots were touching at 100 yards. The ammo fed from my AI magazine perfectly–no problems at all. It seems the ammo is loaded pretty mild. From a 25.3″ barrel, velocity was 2820 fps over my chronograph. This compares with 2790 fps claimed by the factory from a 26″ barrel (see chart below). That 30 fps is easily within barrel to barrel variation (or chrono variation for that matter). So, consider the 123gr 6.5×47 ammo a 2800 fps product. With this 123gr factory load, there were no pressure signs–primer edges were round, there was no significant cratering, and case-head growth was minimal.”

Zak added: “Overall, I was very impressed with this ammo. Accuracy, on the test day, was actually a bit better than my handloads–but it was pretty windy. This stuff is definitely ‘good to go’ for someone who doesn’t reload and wants quality 6.5mm ammo for a tactical match. You won’t have the velocity of a ‘max’ handload, but even at 2800 fps, given the .547 BC of the 123gr Scenar, this ammo easily beats a .308 shooting 175s in terms of long-range ballistics. The chart below shows comparative drift in a 10 mph wind at 600 and 1000 yards.”

Kelbly and Jewell Triggers Compared

We chatted with German Salazar of Shooters Journal at a rimfire match this weekend (which he won). German reminded us that he had done a comparison review of the Jewell and Kelbly. Here is German’s report:

“I received one of Kelbly’s new triggers and installed it on my 6BR Remington 40X. Installation was normal for any Rem-pattern trigger and it fit perfectly. However, the stock (previously inletted for a Jewell trigger), required a slight amount of material removal at the front of the trigger slot as the Kelbly trigger is a bit longer than a Jewell.

Construction of the Kelbly is very robust. It appears to be machined from a solid bar of steel rather than being two end plates screwed together. Perhaps the trigger’s best feature, however, is very wide range of pull-weight available with no changing of springs or other parts. As delivered it was set for approximately 1.5 oz. and broke very cleanly at that weight. Since my application is 300 Meter prone shooting, I raised it to 6 oz. This required moving a pin under the sear bar to the second of four holes and slightly tweaking the weight of pull screw. Compared to other triggers, it was a joy to work with this arrangement and took just a couple of minutes. All adjustments (weight of pull, over-travel, and sear engagement) are made with set screws and their effect on the internal parts can be seen through windows cut into the trigger body. This makes trigger tuning more precise.

On the downside, the barreled action must be removed from the stock to perform the adjustments (unless you use a trigger hanger), but that’s a small price to pay for the overall quality and ease of adjustment. At my current setting of 6 oz. and no over-travel, the trigger breaks like ice. I couldn’t ask for more. Kudos to the good folks at Kelbly’s–they have another winner here.”
