Hornady 30 Cal 180gr InterLock BTSP

Hornady 30 Cal 180gr InterLock BTSP

The Hornady 30 Cal 180gr InterLock BTSP is a premium bullet component engineered for handloaders demanding controlled expansion and deep penetration in .30-caliber hunting rifles. This bullet features Hornady’s proprietary InterLock mechanical bonding system that secures the lead core to the copper jacket, promoting consistent weight retention and structural integrity during high-impact encounters.

This 30 Cal 180gr InterLock BTSP utilizes a boat-tail, spire-point design with a polymer tip that improves ballistic performance and supports reliable expansion at varied velocities. With a G1 ballistic coefficient near 0.480 and sectional density around 0.272, the bullet maintains velocity and resists wind drift. The combination of aerodynamic efficiency and bonded-core construction makes it a compelling choice for long-range hunting applications.

Designed for cartridges such as .30-06 Springfield, .308 Winchester, and 7.62×51 NATO, the 30 Cal 180gr InterLock BTSP is compatible with standard barrel twist rates of 1:10 to 1:11. Precision manufacturing ensures uniform bearing surface length, concentricity, and tip alignment, supporting consistent seating depth and repeatable handloaded rounds capable of sub-MOA accuracy.

In field use, the 30 Cal 180gr InterLock BTSP exhibits reliable terminal performance on game like deer, elk, and black bear. At typical hunting velocities around 2,700 to 2,800 fps, this bullet expands in a controlled manner while retaining over 90 percent of its weight, delivering deep wound channels and ethical kills. The bonded-core prevents jacket-core separation and maintains bullet integrity through heavy hide and bone.

Manufactured in Grand Island, Nebraska, the Hornady 30 Cal 180gr InterLock BTSP is sold as a bullet component only and requires handloaders to supply their own brass, powder, and primers. Hornady’s strict quality control measures ensure consistent ogive shape, tip seating, and weight uniformity across every bullet, making it a reliable option for serious hunters seeking both precision and terminal effectiveness.

Overall, the Hornady 30 Cal 180gr InterLock BTSP bullet component combines aerodynamic boat-tail efficiency, bonded-core reliability, and controlled expansion characteristics. It stands out as a versatile choice for handloaders preparing ammunition for medium to large game in .30-caliber cartridges, offering consistent accuracy and dependable performance in the field.
