Hornady 2820 InterLock .284 Diameter 139 Grain Spire Point 7mm Reloading Bullets, 100 Count

Hornady Part Number 2820 InterLock reloading bullets are designed for reliable performance in 7mm rifle cartridges. Each .284-inch diameter projectile features a 139-grain spire point profile that supports a flat trajectory and dependable accuracy when paired with appropriate loading data. With a ballistic coefficient of .392 and a sectional density of .246, these bullets are suitable for handloaders seeking consistent component specifications for hunting and general-purpose rifle applications.
The InterLock design incorporates a raised ring inside the jacket that is embedded into the lead core. This feature helps keep the copper jacket and lead core together during expansion, supporting controlled weight retention and energy transfer. The tapered jacket has precisely controlled thickness to promote reliable expansion across a broad range of velocities, while the one-piece core helps reduce the potential for core and jacket separation.
A cannelure provides a defined location for accurate, consistent crimping and works with the InterLock ring to help maintain the connection between the core and jacket during expansion. The copper jacket and lead core provide the construction expected from a traditional hunting bullet, while the spire point design offers an aerodynamic profile for practical field use. These Hornady bullets are intended for reloaders who value repeatable construction and dependable performance from every component.
Each box contains 100 bullets. Use only current, published load data and follow safe reloading practices for the specific cartridge, firearm, powder, primer, and bullet combination. Verify bullet diameter, seating depth, crimping requirements, and other loading specifications before use.
