Hornady 338 Cal 225gr InterLock SP-RP

Hornady 338 Cal 225gr InterLock SP-RP

The Hornady 338 Cal 225gr InterLock SP‑RP is a premium bonded-core bullet component created for handloaders and hunters who need controlled expansion, deep penetration, and precise accuracy in .338-caliber platforms. Weighing exactly 225 gr with a .338‑inch diameter, the 338 Cal 225gr InterLock SP‑RP features Hornady’s InterLock® core-to-jacket bonding system with a secured polymer tip and spire‑point/round‑point profile, which preserves over 90% of its mass while offering reliable terminal performance on medium and large game.

The aerodynamic design of the Hornady 338 Cal 225gr InterLock SP‑RP is optimized with a polymer tip and closely matched ogive that enhances ballistic coefficient and stabilizes trajectory from muzzle to impact. When loaded to velocities between 2,650 and 2,850 fps in cartridges such as .338 Winchester Magnum or .338 Lapua Magnum, the bullet sustains energy, reduces drift in crosswinds, and delivers shot‑string consistency at ranges up to 500 yards.

Featuring a bonded-core, the Hornady 338 Cal 225gr InterLock SP‑RP utilizes Hornady’s mechanical InterLock® ring to firmly secure the lead core within the copper jacket. This prevents jacket-core separation and enables deep, uniform wound channels through dense muscle and intermediate bone. Hunters and handloaders report that the 338 Cal 225gr InterLock SP‑RP consistently mushrooms with retention and penetrates straight, even in brush or challenging terrain.

The bullet stabilizes effectively in barrels with common twist rates of 1:10 and 1:11 and feeds reliably in bolt-action, magazine, and single-shot platforms. Its concentric jacket, polished ogive, and dependable bearing surface support smooth cycling, tight groupings, and repeatable point-of-impact. Reloaders appreciate how the 338 Cal 225gr InterLock SP‑RP maintains accuracy across a variety of powders, primers, and seating depths.

Manufactured at Hornady’s Grand Island, Nebraska facility, the Hornady 338 Cal 225gr InterLock SP‑RP is sold strictly as a bullet component and must be paired with compatible brass, powder, and primers. With detailed quality control conducted on tip alignment, jacket concentricity, and weight consistency, the 338 Cal 225gr InterLock SP‑RP stands as a standout choice for hunters seeking bonded-core reliability, flat terminal performance, and precision in .338-caliber bullet applications.
