The Hornady InterLock Round Nose is a classic hunting component bullet for reloaders working with .303 calibre rifles. At .312" diameter and 174 grains, this heavier round-nose projectile is designed for close-to-medium range stalking and woodland shooting where the blunt profile aids reliable feeding through tubular magazines and lever-action or bolt-action rifles. The round nose profile combined with an exposed lead tip promotes controlled expansion on impact, while the exclusive InterLock ring — a raised feature embedded in the bullet's core — holds the jacket and core together throughout expansion to retain mass and ensure deep, consistent penetration. Inner grooves in the jacket create controlled weak points that initiate reliable expansion even at reduced velocities, and the tapered jacket thickness is precisely engineered across the bullet's length for consistent performance at all practical ranges. A one-piece core prevents the core-jacket separation associated with two-piece designs, delivering the large, consistent wound channels needed for a clean kill. A cannelure provides a positive crimp location and works alongside the InterLock ring to maintain bullet integrity during expansion. Sold as component projectiles — no FAC required to purchase in the UK.
