Hornady XTP (45100) component bullets give reloaders a light, fast 45 caliber hollow point for handloading 45 ACP, 45 Colt, and related cartridges where controlled expansion and match-grade accuracy are the priority. These 45 caliber .451 diameter 185 grain jacketed hollow point bullets pack 100 per box and are a proven reloading component for self-defense handloaders, competitive shooters, and hunters who want a high-velocity 45 caliber hollow point that expands reliably across a wide range of handgun velocities.

Special Features
- Drawn gilding metal jacket varies in wall thickness down the length of the bullet, initiating controlled expansion even at velocities as low as 800 fps where standard hollow points often fail to open.
- Six precise serrations divide the XTP into symmetrical sections, strategically weakening the jacket to prevent fragmentation at higher velocities while still delivering full expansion at lower ones.
- Swaged lead core delivers total uniformity in density, supporting balanced expansion and consistent in-flight stability from compact carry pistols through full-size competition handguns.
- Enclosed nose design protects the hollow cavity so it functions correctly on impact and feeds reliably through the feeding ramps of semi-automatic 45 ACP pistols.
- Heavier jacket construction handles the elevated pressures of hot 45 ACP and 45 Colt handloads without sacrificing the expansion performance the XTP platform is built around.
Practical Benefits
- The 185 grain weight is a lighter-for-caliber option in 45, producing higher velocities than 230 grain loads and making it a strong fit for defensive handloaders who want a faster, flatter-shooting 45 ACP round.
- Competitive shooters building precision handloads for 45 ACP pistols get the consistent core geometry and jacket quality that produces tight groups and predictable point of impact across extended range sessions.
- Hunters running 45 Colt revolvers for small to medium game will find the XTP expands reliably across the broad velocity window that different barrel lengths produce.
- Your handloads built on the Hornady XTP (45100) deliver terminal performance on par with factory defensive ammunition, giving you a high-confidence 45 caliber component for the range, field, or home.
The Hornady XTP (45100), a 45 caliber .451 diameter 185 grain jacketed hollow point, is a reliable pick and proven platform for reloaders who need a fast, accurate, and consistently expanding bullet for 45 ACP self-defense, competition, and hunting applications.
