Remington Core-Lokt .300 Remington Ultra Magnum 180gr PSP Ammo, 20-Round Box

Remington Core-Lokt .300 Remington Ultra Magnum 180-grain Pointed Soft Point ammunition (brand part no. 27641) pairs one of the hardest-hitting magnum cartridges Remington builds with the bullet that has anchored its hunting line for more than 75 years. Remington locks the tapered copper jacket to a solid lead core, delivering controlled 2X expansion, strong weight retention, and consistent terminal results on game that has made Core-Lokt the first choice for generations of hunters. The .300 RUM adds significant velocity and energy over standard magnums, stretching effective range on big-bodied animals without asking the bullet to do something it was not built for. This is rifle ammunition built for hunters who want flat trajectory and knockdown power in the same box.
