Hornady 30 Cal 180gr InterLock RN

The Hornady 30 Cal 180gr InterLock RN is a reliable bullet component crafted for handloaders who require consistent expansion, high weight retention, and deep penetration in .30-caliber hunting cartridges. Weighing 180gr with a .308-inch diameter, the 30 Cal 180gr InterLock RN features a classic round-nose profile and Hornady’s proven InterLock® core-bonding system. This design delivers consistent terminal performance on medium to large game while ensuring compatibility with a wide variety of rifle platforms.

The 30 Cal 180gr InterLock RN utilizes Hornady’s InterLock® ring—a mechanical bond that fuses the lead core to the copper jacket—helping the bullet retain more than 90% of its mass on impact. This structural integrity allows the 30 Cal 180gr InterLock RN to drive deep into tissue, breaking through bone and maintaining its trajectory for ethical, effective takedowns. It is particularly suited for close to mid-range hunting scenarios where maximum penetration and expansion are critical.

The round-nose geometry of the 30 Cal 180gr InterLock RN provides reliable feeding and uniform chamber alignment, especially in lever-action rifles and other platforms using tubular magazines. Its smooth profile and balanced weight distribution contribute to consistent accuracy and stable flight. Handloaders appreciate the 30 Cal 180gr InterLock RN for its ability to deliver predictable results across cartridges like the .30-30 Winchester, .308 Marlin Express, and others tailored to traditional hunting roles.

Ballistically, the 30 Cal 180gr InterLock RN benefits from a tapered jacket and consistent bearing surface, offering controlled expansion and minimal jacket separation. The bullet performs reliably in barrels with 1:10 or 1:12 twist rates, stabilizing well and grouping consistently at typical hunting distances of 100 to 200 yards. Whether used in vintage rifles or modern bolt guns, the 30 Cal 180gr InterLock RN delivers dependable on-target results.

Manufactured at Hornady’s Grand Island, Nebraska facility, the 30 Cal 180gr InterLock RN is sold as a bullet component and requires pairing with suitable powder, primers, and brass. With strict quality control over jacket concentricity, weight uniformity, and bonding integrity, the Hornady 30 Cal 180gr InterLock RN stands as a trusted solution for serious hunters and reloaders who prioritize performance in .30-caliber hunting loads.
