HORNADY 45177 45 CAL .451 230 GR FMJ-RN 100 CNT

Hornady's 45 Cal .451 230 Grain FMJ-RN component bullets (45177) are precision-made reloading projectiles designed for handloaders working up .45 ACP, .45 Auto Rim, .45 Colt, and other .451-diameter cartridges for target shooting, action pistol competition, and high-volume range training. If you reload your own handgun ammunition and need a consistent, well-built 230 grain full metal jacket round nose bullet that feeds reliably in semi-automatic pistols, this is a proven platform to build your loads around.

Special Features

• Hornady's AMP jacket, short for Advanced Manufacturing Process, is drawn to near-perfect concentricity with minimal jacket thickness variation from base to nose, producing consistent in-flight stability across a full range of powder charges.
• The cold-swaged lead core eliminates voids and density variations inside the bullet, giving each projectile a uniform weight distribution that translates directly to shot-to-shot accuracy.
• The FMJ-RN profile fully encases the nose of the bullet in copper jacket material, protecting the lead core and ensuring smooth, reliable feeding through semi-automatic actions including 1911-pattern pistols and high-capacity double-stack platforms.
• Hornady removes expansion-aiding skives from this FMJ design intentionally, prioritizing clean penetration and consistent grouping over terminal expansion, making it purpose-built for target and competition use rather than defensive applications.
• The .451 diameter and flatbase construction make this bullet compatible with a wide range of .45 ACP, .45 Auto Rim, .45 Colt, .450 Bushmaster, and .45 GAP loading dies and brass.

Practical Benefits

• The 230 grain FMJ-RN is the classic standard-pressure .45 ACP bullet weight, so your loads will closely replicate factory ball ammunition pressure curves, making this an ideal starting point for building your first .45 ACP load or refining an existing recipe.
• At 100 bullets per box, this pack suits handloaders who want to work up a new load, test a new powder combination, or fill out a smaller batch without committing to a 500-count bulk purchase.
• The consistent jacket concentricity means your sized and crimped rounds feed and extract cleanly in semi-automatic pistols, reducing the chance of a nose-dive or feed jam during competition or training strings.
• Reloaders running action pistol formats such as USPSA, IDPA, or Steel Challenge will find this bullet produces accurate, flat-shooting .45 ACP loads that meet power factor requirements at standard charge weights.
• Because this bullet loads to standard .45 ACP overall length and uses common flatbase geometry, it works with every major reloading press and seating die on the market without modification.
• If you handload .45 ACP and want a component bullet that delivers match-level consistency without paying a premium price per round, the Hornady 45177 gives your reloading bench a dependable foundation for every range session.

The Hornady 45 Cal .451 230 Grain FMJ-RN (45177) is a reliable pick for competitive shooters and serious handloaders who demand consistent performance from every bullet they seat.
