6.5×55 SE GB582 9,3 g / 144 gr OTM MaxRT Cartridge

The 6.5×55 SE is one of the most popular all-around ammo in the world for target shooters. The 6.5×55 Swedish cartridge is especially popular in the Scandinavian countries, including traditional long-range field shooting disciplines. The old horse which will never die.

Loaded with Lapua’s 6,5 mm GB582 9,3 g / 144 gr MaxRange Target bullet, this high BC cartridge offers a streamlined trajectory, and improved stability for extended distances with pinpoint precision of unmatched long-range performance.

The new bullet and cartridge expand Lapua’s already extensive 6.5×55 SE product range to even longer shooting distances and offer sports shooters something that has not yet been available on the market.

Use the product together with Lapua Ballistics® and you can be sure of a hit.

The 6.5 Creedmoor GB582 9,3 g / 144 gr OTM MaxRT cartridge will be available in spring 2026.
