Lapua 8x57 IS 120 Grain Open Tip Brass Cased Rifle Ammo 20 Rounds. Lapua Sales Manager Erkki Seikkula explains the thought process behind their new 8mm 78 g/ 120 grain OT bullet: "We designed an easy and softly firing bullet that meets Lapua's strict accuracy requirements. The precision of this bullet offers shooters the opportunity to practice with the same rifle that they hunt with. For avid hunters that enjoy target competitions the performance of this projectile can really make a difference." A notable advantage of the bullet and the factory-loaded cartridge is that the bullet's point of impact coincides with the Lapua Naturalis hunting projectile making this ammo ideal for hunting practice.
