Hornady Precision Hunter .300 RSAUM ammunition (part no. 82144) loads a 178-grain ELD-X Polymer Tip for big-game hunters who want confirmed, repeatable terminal performance. Hornady builds its ammunition around match-grade bullets designed in-house, giving hunters and shooters factory-loaded consistency. The Heat Shield tip resists melting from friction at high velocity, so expansion starts on cue instead of blunting the nose before impact. Brass-cased and 20 to a box, it is built to feed reliably through bolt guns and semi-autos chambered for the cartridge. In our rifle ammunition lineup, this .300 RSAUM loading is a confirmed, dependable choice worth adding to the cart.
