Sierra 45 Cal 300gr HP/FN

The Sierra 45 Cal 300gr HP/FN is a heavy-duty component bullet tailored for handloaders and hunters seeking deep penetration, controlled expansion, and dependable accuracy in .45‑caliber firearms. Featuring a .452‑inch diameter and a 300‑grain hollow-point flat-nose profile, this bullet is optimized for use in lever-action rifles and revolvers chambered in .45 Colt and .45‑70 Government.

Constructed with a durable copper-alloy jacket over a lead core, the 300gr HP/FN design offers gradual and uniform expansion upon impact. The flat-nose profile ensures smooth feeding in tubular magazines and lever-action firearms while promoting deep energy transfer—ideal for medium to large game and brush hunting.

Manufactured to Sierra’s exacting component standards—300.0 grains weight, 0.452″ diameter, and a sectional density near 0.286—the bullet features consistent jacket thickness, precise hollow-point cavity shaping, and a visible cannelure for secure crimping. These qualities support repeatable seating, stable pressures, and consistent terminal performance.

Optimized for velocities between 1,200 fps and 1,800 fps in lever-action rifles and revolvers, the 300gr HP/FN delivers reliable terminal effect and accuracy. Handloaders report dependable performance for hunting deer, wild hogs, or large predators in close-range brush scenarios, with minimal fragmentation and strong penetration.

As a component bullet, the Sierra 45 Cal 300gr HP/FN gives reloaders full control over powder selection, primer choice, and seating depth—allowing tailored load crafting for specific recoil, velocity preferences, and terminal objectives. It is not factory-loaded ammunition but a versatile hollow-point flat-nose component designed for serious .45-caliber applications.
