Hornady 270 Cal 6.8mm 150gr InterLock SP

The Hornady 270 Cal 6.8mm 150gr InterLock SP is a premium bullet component designed for expert handloaders seeking a balanced blend of accuracy, cost-effective performance, and terminal reliability in .270 Winchester and 6.8mm cartridges. Featuring a .277‑inch diameter and a weight of 150gr, this bullet uses Hornady’s proven InterLock mechanical bonding system to secure the lead core to the copper jacket. This construction ensures controlled expansion, over 90 percent weight retention, and dependable performance under varied field conditions.

Designed with a spire-point, boat-tail profile, the 270 Cal 6.8mm 150gr InterLock SP provides excellent aerodynamic performance. Its polymer tip and secant ogive support a high G1 ballistic coefficient in the range of 0.450–0.470, resulting in flat trajectory and reduced wind drift. These characteristics make it suitable for cartridges such as the .270 Winchester, 6.8mm SPC, and similar medium-bore magnums, offering consistent accuracy and retained energy downrange.

The 270 Cal 6.8mm 150gr InterLock SP requires standard barrel twist rates—from 1:9 to 1:10—to stabilize effectively in bolt-action and modern sporting rifles. Precision in bearing surface length, ogive geometry, and tip alignment ensures uniform seating and consistent handloaded performance. Reloaders will find the component easy to load and reliable in cycling through magazine-fed platforms, maintaining tight group sizes through repeatable seating depth.

In practical field conditions, the 270 Cal 6.8mm 150gr InterLock SP excels on game like deer, antelope, and elk. At typical hunting velocities between 2,800 and 2,900 fps in .270 Winchester setups, the bullet expands early and retains most of its weight, creating deep wound channels while minimizing fragmentation. The bonded core and robust jacket resist separation through heavier bone and shoulder tissue, delivering ethical terminal results with predictable penetration and expansion.

Manufactured in Hornady’s Grand Island, Nebraska facility under stringent quality control measures, each 270 Cal 6.8mm 150gr InterLock SP is sold as a component only. Compatible brass, powder, and primers must be selected by the handloader. Hornady’s manufacturing precision ensures consistent concentricity, weight variation, and tip alignment, all contributing to consistent muzzle velocities and bullet flight.

Overall, the Hornady 270 Cal 6.8mm 150gr InterLock SP bullet component combines aerodynamic efficiency, bonded-core durability, and adaptable terminal performance. Its polymer-tip boat-tail design and proven InterLock bond make it a go-to choice for reloaders seeking a versatile, accurate, and reliable bullet that delivers consistent results on medium and large game at varied ranges.
