Sub-MOA groupings with the Sako TRG M10 in .308 Win and .338LM

    Three holes in a paper at 100 meters. Some times these groupings come together, sometimes they don’t.

    In a SAKO TRG M10, considering its price and all the premium components involved in this system, you would think that the groupings would always come together

    We’ve tested the M10 with both the 308 Win and the 338 Lapua Magnum barrels. That’s a fine thing with the TRG M10, you can switch barrels.

    For the 308 Win we used one of the least expensive factory ammunition on the market: GGG .308W ammunition, 147 Grain FMJ (7,62×51 NATO), from Lithuania. They supply to a lot of Armies in Europe, so don’t be fooled that a relatively low cost means low quality in this case.

    Definetly a sub MOA grouping. The tanned square stickers are 17×17 mm as a reference, so I’d say the group is about 10-12 mm. 5 shots of 308, but it looks like 3, from the owner of the rifle.

    For the 338 Lapua Magnum we zeroed it at 100 meters, then took it to 300 meters immediately for groupings. Interestingly, the ballistic app iStrelok Pro worked flawlessly to foresee the right amount of clicks. The money we saved on ammunition is definitely worth the price of the app.

    Below: Three Three Three Eight Lapua Magnums (now repeat that fast ten times, good luck).

    These were shot at 300 meters, and sub-MOA. The recoil was relatively mild, but don’t have your nose too close to the scope if you’re not holding the rifle tight. Only 3 shots on this picture, but this performance was repeatable. I guess the factor which adds the most uncertainty is the shooter, not the system or the factory load.
