Hornady 45100 XTP 45 Caliber .451 185 GR Hollow Point 100 Box

The Hornady XTP 45 Caliber .451 185 GR Hollow Point bullets are a proven choice for reloaders who demand reliable expansion and consistent performance across the velocity ranges typical of 45 ACP handloads. Whether you're building ammunition for defensive carry, hunting medium game, or competitive shooting, these jacketed hollow points have earned their reputation through decades of real-world use. The 185-grain weight is the classic .451 diameter standard, delivering the balance of penetration and expansion that serious shooters expect.

What sets the XTP apart is its engineering. The bullet uses a swaged core for uniform density, which translates to balanced expansion and stable flight. The drawn gilding metal jacket has varying thickness along its length—thicker at the nose, thinner toward the base—which controls expansion predictably even when velocities dip below typical service loads. This matters if you're experimenting with lighter loads or working in revolvers where velocity can be inconsistent. Precise serrations weaken the jacket symmetrically, initiating controlled mushrooming rather than fragmentation.

On revolver loads, the cannelure (applied before final forming to prevent distortion) gives you a secure, repeatable crimp seat. That consistency carries through to the press, shot after shot. You get 100 bullets per box, so you can develop and test loads thoroughly without rationing components.

Frequently Asked Questions

What firearms are these bullets designed for?

These .451 diameter, 185-grain XTP bullets are sized for 45 ACP rifles, pistols, and revolvers. Always verify bullet diameter and weight compatibility with your specific firearm and load data before reloading.

Why do XTP bullets have serrations and varying jacket thickness?

The serrations are strategically placed to weaken the jacket symmetrically, initiating controlled expansion at a wide range of velocities. The varying jacket thickness (thicker at the nose, thinner toward the base) gives Hornady XTP bullets an advantage in expansion control compared to plated bullets with uniform jacket thickness. This design ensures reliable performance even at lower velocities typical of some handgun loads.

Is the cannelure useful for semi-automatic reloading?

The cannelure helps achieve repeatable, accurate crimping on revolver rounds. For semi-automatic 45 ACP loads, the cannelure serves as a reference point for consistent seating depth but is not required for function.

What's included in the 100-box?

You receive 100 projectiles per box. You'll need to source primers, powder, and brass cases separately to complete your handloads.
