Hornady 45 Cal 350gr InterLock FP

The Hornady 45 Cal 350gr InterLock FP is a heavy-duty bullet component crafted for handloaders needing deep penetration, controlled expansion, and consistent accuracy in .45‑caliber rifles and revolvers. Weighing 350 gr with a .452‑inch diameter, the 45 Cal 350gr InterLock FP features Hornady’s InterLock® core-to-jacket bonding system, ensuring over 90% weight retention and dependable terminal performance across various bullet velocities.

Featuring a flat-point (FP) profile and precisely engineered jacket geometry, the 45 Cal 350gr InterLock FP delivers a blunt frontal impact ideal for heavy muscle or bone penetration. When loaded between 900 and 1,200 fps in platforms like .45-70 Government, .450 Marlin, or large-frame revolvers, the 45 Cal 350gr InterLock FP offers consistent wound channels, straight-line penetration, and dependable performance in dense brush or close-range hunting situations.

The bonded-core construction in the 45 Cal 350gr InterLock FP mechanically locks the lead core to the jacket via Hornady’s InterLock® ring, preventing jacket-core separation during terminal events. This ensures the bullet penetrates deeply through heavy tissue and bone while maintaining structural integrity. Field users report clean, large wound tracks and reliable terminal results with the 45 Cal 350gr InterLock FP.

Stabilizing effectively in barrels with common twist rates of 1:16 to 1:18, the 45 Cal 350gr InterLock FP feeds reliably in bolt-action, lever-action, .45-70 rifles, and revolvers. Its concentric jacket and consistent bearing surface support accurate feeding and spacious seating. Reloaders appreciate the 45 Cal 350gr InterLock FP for tight groupings, repeatable point-of-impact, and smooth cycling across various load configurations.

Manufactured at Hornady’s Grand Island, Nebraska facility, the Hornady 45 Cal 350gr InterLock FP is sold as a bullet component only and must be loaded with compatible brass, powder, and primers. With strict quality control over jacket thickness, tip alignment, and weight uniformity, the 45 Cal 350gr InterLock FP serves as a top-tier bonded-core option for hunters seeking deep penetration, ethical terminal performance, and reliable accuracy in .45‑caliber bullet applications.
