Hornady 9.3mm 286gr InterLock SP-RP

Hornady 9.3mm 286gr InterLock SP-RP

The Hornady 9.3mm 286gr InterLock SP‑RP is a premium bullet component tailored for handloaders requiring reliable performance on large and dangerous game. Crafted with a .366‑inch diameter and weighing 286gr, this projectile integrates Hornady’s InterLock mechanical bonding system, which locks the lead core securely to the copper jacket, ensuring structural integrity and over 90 percent weight retention during expansion. Its spire-point (SP) design with a robust polymer tip and boat-tail (RP) base delivers enhanced aerodynamic efficiency and terminal performance.

Designed for powerful medium-bore cartridges such as the 9.3×62mm Mauser and 9.3×64mm Brenneke, the 9.3mm 286gr InterLock SP‑RP requires standard twist rates between 1:10 and 1:12 to stabilize effectively in both bolt-action and controlled-round-feed rifles. The precise manufacturing tolerances ensure consistent bearing surface, ogive shape, and tip alignment—factors crucial for maintaining sub‑MOA accuracy potential and repeatable handloading results across various powder and seating-depth configurations.

This bullet’s polymer-tipped spire-point profile promotes controlled expansion at typical hunting velocities between 2,450 and 2,600 fps, enabling rapid mushrooming while preserving structural integrity thanks to the InterLock bond. The boat-tail base stabilizes flight trajectory and reduces drag, resulting in a G1 ballistic coefficient estimated near 0.380. Such efficiency supports flat shooting and wind resistance, making it effective for shots taken at extended ranges or in open-country scenarios.

In field applications, the 9.3mm 286gr InterLock SP‑RP demonstrates deep-penetrating yet controlled terminal performance on heavy-skinned, thick-boned game such as moose, brown bear, and elk. At typical hunting velocities, the bonded core and tough jacket resist fragmentation, ensuring the bullet retains mass and passes through efficiently. Hunters appreciate the reliable wound channel formation and heavy mass retention—key for ethical one-shot takedowns in dangerous situations.

Manufactured exclusively at Hornady’s Grand Island, Nebraska facility, each 9.3mm 286gr InterLock SP‑RP bullet is sold as a component only. Handloaders must supply brass, powder, and primers to complete the cartridge. Hornady’s stringent quality control governs weight consistency, concentricity, and tip alignment, promoting repeatable performance and accuracy in precision-chambered dangerous-game rifles—even under rigorous field conditions.

Beyond dangerous game, this bullet component also serves well for long-range big game hunting. Its combination of aerodynamic boat-tail design, bonded-core durability, and polymer-tip initiation make it versatile in varied hunting environments—from thick brush to alpine treelines. Whether loaded into 9.3×62mm or modern dangerous-game platforms, the 286gr InterLock SP‑RP offers a dependable balance of expansion, penetration, and ballistic consistency for serious hunters.

Overall, the Hornady 9.3mm 286gr InterLock SP‑RP bullet component delivers a powerful blend of aerodynamic performance, bonded-core strength, and controlled expansion. It stands as a top-tier choice for handloaders building ammunition tailored to hunting large and dangerous game in heavy-caliber 9.3mm platforms, offering deep penetration, reliable terminal effect, and consistency from one shot to the next.
