The Hornady InterLock 35 Cal 170 gr Spire Point (Hornady part no. 3501) is part of Hornady’s traditional bullet line, built with an exposed lead tip for controlled expansion and hard-hitting terminal performance on game or targets shot with .355-inch rifles. Most InterLock spire-point profiles use Hornady’s secant ogive design, one of the most ballistically efficient profiles the company builds. At the heart of the design is Hornady’s InterLock ring, a raised ridge inside the jacket that’s embedded directly in the bullet’s core, mechanically locking core and jacket together through expansion so the bullet retains mass and energy instead of shedding its jacket on impact.

Key Specifications

• Bullet diameter matches .355-inch rifle cartridges.
• Bullet weight is 170 grains, sized for this specific InterLock loading.
• Bullet profile is a Spire Point, shaping how it flies and expands on impact.
• Built around Hornady’s InterLock ring, which mechanically locks the jacket to the core during expansion to retain mass and energy.
• Jacket thickness is precisely tapered so the bullet expands reliably across a range of impact velocities without the core separating.
• A cannelure is included for accurate, consistent crimping that also helps the InterLock ring keep core and jacket locked together.
• Packaged 100 bullets per box, a standard box count for this loading.

Is this bullet meant for hunting or target work? Hornady builds the InterLock line around controlled expansion and hard-hitting terminal performance, which is the profile hunters look for in a big-game or varmint bullet at .355-inch.
