Hornady Superformance .444 Marlin 265gr InterLock FP 20rd

Description

The Hornady Superformance .444 Marlin stands out because it pushes 265-grain InterLock bullets to 2400 fps – making it the fastest straight-wall rifle cartridge on the market. You get that velocity bump through progressive propellants rather than brute-force powder loads, which means no extra recoil, no additional chamber pressure, and no temperature sensitivity. This is the kind of performance that actually shows up in the field.

Superformance Propellant Technology

The heart of this load is Hornady's progressive propellant formula. Unlike conventional ammunition that relies on heavy powder charges to push velocity, Superformance uses specialized powders at normal charge weights. This approach directs all useable energy into the bullet while reducing muzzle blast and felt recoil. You're looking at 100 to 200 fps faster than standard .444 loads, and the ballistic benefit carries downrange with a noticeably flatter trajectory and less wind drift.

InterLock Bullet Construction

The 265-grain InterLock flat-point bullet is what makes this round a serious hunting tool. The InterLock ring mechanically locks the core to the jacket, delivering controlled expansion and deep penetration whether you're hunting deer or larger game. The full-profile jacket and flat-nose design cycle smoothly through lever-action magazines while the bullet's sectional density ensures it carries energy to where it counts. With 3389 foot-pounds of muzzle energy, this isn't a light load.

Built for Lever Guns and More

This ammunition works reliably in lever-actions, pump-actions, and semi-automatic rifles chambered in .444 Marlin. The brass cases are reloadable, and the consistency of each component – from the primer to the case – translates to consistent shooting in the field. At 100 yards, you're still carrying nearly 2300 foot-pounds of energy, giving you plenty of margin for ethical hunting shots out to reasonable distances.
