Remington, Core-Lokt, 300 Remington Ultra Magnum, Tipped, 180 Grain, 20 Rounds

The Remington Core-Lokt Tipped rifle ammunition in 300 Remington Ultra Magnum, 180 grain, delivering a published 3150 fps, is built for hunters who chase elk, moose and other big game out to extended distances and need reliable terminal performance; as part of the Core-Lokt Tipped series this round pairs the proven Core-Lokt jacket tuned for controlled, devastating expansion with a big green polymer tip that improves long-range ballistics, stabilizes in-flight accuracy and helps initiate rapid expansion on impact. The cartridge's match-grade accuracy comes from a center-of-gravity adjusted rearward design that tightens groups and flattens trajectory, making follow-up shots and ethical shot placement more consistent at varying ranges in mountain, plains and timber hunting scenarios. Remington's Core-Lokt legacy means hunters can count on deep penetration and weight retention when hunting heavy-bodied game, while the tipped profile gives better ballistic coefficient for wind resistance and downrange energy retention—useful for long stalking shots or steep-angle takes where drop and drift matter. If you're comparing 300 Rem Ultra Mag ammo for big-game hunting or precision hunting loads, this Core-Lokt Tipped offering balances trajectory, terminal power and repeatable on-game performance.
