Hornady 375 Cal 270gr InterLock SP‑RP

The Hornady 375 Cal 270gr InterLock SP‑RP is a premium bullet component designed for handloaders and hunters who require deep penetration, controlled expansion, and consistent accuracy in .375‑caliber rifles. Weighing 270 gr with a .375‑inch diameter, the 375 Cal 270gr InterLock SP‑RP features Hornady’s InterLock® core-to-jacket bonding system, delivering over 90% weight retention and reliable terminal performance on large and dangerous game.

Featuring a spitzer-point profile with a polymer tip and boat-tail base, the 375 Cal 270gr InterLock SP‑RP achieves a high ballistic coefficient and flattened trajectory. When driven at velocities around 2,600 fps in cartridges such as .375 H&H Magnum and .375 Ruger, the 375 Cal 270gr InterLock SP‑RP delivers predictable downrange energy and excellent resistance to wind drift—ideal for long-range hunting.

Internally, the bonded-core construction in the 375 Cal 270gr InterLock SP‑RP mechanically locks the lead core to the jacket via Hornady’s InterLock® ring, preventing separation upon impact. This ensures the bullet penetrates deeply through heavy muscle and bone while maintaining structural integrity. Field tests show the 375 Cal 270gr InterLock SP‑RP produces clean wound channels and consistently delivers ethical terminal results.

Stabilizing effectively in barrels with typical twist rates of 1:10 to 1:12, the 375 Cal 270gr InterLock SP‑RP feeds smoothly in bolt-action and magazine-fed rifles. Its concentric jacket, polished ogive, and consistent bearing surface support tight grouping and reliable feeding. Reloaders value the 375 Cal 270gr InterLock SP‑RP for precise point-of-impact and consistent performance across varied loads.

Manufactured at Hornady’s Grand Island, Nebraska facility, the Hornady 375 Cal 270gr InterLock SP‑RP is sold as a bullet component and requires compatible brass, powder, and primers. With strict quality control over tip alignment, jacket bonding, and weight uniformity, the 375 Cal 270gr InterLock SP‑RP stands as a top-tier choice for serious hunters seeking controlled expansion, durability, and flat-shooting performance in .375‑caliber rifle applications.
