Hornady 45 Cal 350gr InterLock RN

The Hornady 45 Cal 350gr InterLock RN is a heavy-hitting bullet component designed for handloaders seeking deep penetration, weight retention, and reliable terminal performance in .45-caliber rifles. Weighing 350gr with a .452-inch diameter, this InterLock RN bullet features Hornady’s mechanical bonding system—locking the lead core to the copper jacket to maintain structural integrity and deliver over 90% weight retention at impact.

Featuring a round-nose profile, the 45 Cal 350gr InterLock RN supports smooth feeding and consistent ballistics in cartridges like .45‑70 Government, .450 Bushmaster, and .458 Winchester Magnum. The blunt nose and solid profile help preserve velocity and penetration, making the 45 Cal 350gr InterLock RN ideal for big‑game hunting and dangerous-game applications.

Engineered for barrels with twist rates of 1:16 to 1:18, the Hornady 45 Cal 350gr InterLock RN stabilizes well in bolt-action and lever-action rifles. Precision in bearing surfaces, ogive contour, and jacket thickness supports repeatable seating depth and muzzle velocity. Reloaders value the 45 Cal 350gr InterLock RN’s consistent performance and smooth cycling in magazine-fed platforms.

In field conditions, this bullet delivers dependable terminal effects. At typical hunting velocities of 2,100–2,300 fps, the bonded-core construction of the 45 Cal 350gr InterLock RN resists fragmentation and drives deeply through heavy bone and dense muscle. The result is reliable wound channels and strong stopping power—ideal for elk, moose, bear, and other large-bodied game.

Manufactured at Hornady’s Grand Island, Nebraska facility, each 45 Cal 350gr InterLock RN component is sold as a bullet only. Handloaders must use appropriate brass, powder, and primers. With Hornady’s tight quality control on weight consistency, concentricity, and jacket-core bonding, the 45 Cal 350gr InterLock RN delivers precision, power, and penetration for serious hunters and reloaders.
