The Hornady .312 32 Cal 100 Grain HP/XTP bullet is a component projectile engineered for handloaders seeking controlled expansion and terminal performance. Designed for .32-calibre handgun and rifle cartridges, this jacketed hollow point features a 100-grain weight, a .312-inch (7.92 mm) diameter, and an in-line cannelure for consistent crimping. Drawn gilding metal with progressive sidewall thickness works alongside symmetrical jacket serrations to initiate controlled expansion up to 1.5 times the bullet diameter without fragmenting.

Key Features

• Controlled Terminal Expansion: Symmetrical serrations cut into the upper jacket deliberately weaken the cavity rim to initiate expansion at lower speeds, while the progressive sidewall thickness prevents premature fragmentation.
• Cold-Swaged Core: Uniform lead-core density maintains rotational balance and structural integrity across the standard velocity envelope.
• In-Line Cannelure: Precisely rolled cannelure delivers secure, uniform revolver roll-crimping without distorting the internal core symmetry.
• Cartridge Compatibility: Sized for handloading into .312-diameter platforms including .32 H&R Magnum, .327 Federal Magnum, .32 S&W Long, as well as light-bullet loads for .303 British and 7.62x39mm bores (.310–.312 in).

Who is the Hornady .312 32 Cal 100 Grain HP/XTP Bullets 100 Pack for?

• Handloaders loading .32 H&R Magnum and .327 Federal Magnum — requires a .312-inch diameter component projectile designed with an in-line cannelure to seat securely against revolver recoil while retaining a sectional density of 0.147.
• Pest controllers targeting small game under 50 lbs — relies on the 100-grain hollow point design to achieve reliable mushrooming and energy transfer within an operating impact velocity window of 800 to 1,300 fps at distances up to 100 metres.
• Competitive target shooters using .312 calibre handloads — utilises the rotational balance of a cold-swaged lead core with a G1 ballistic coefficient of 0.170 for predictable trajectory and short-range accuracy.

Less suitable for: Target animals exceeding 50 lbs (22.7 kg) or loads generating impact velocities above 1,300 to 1,400 fps, where heavier bonded hunting rifle projectiles are required to ensure ethical penetration depth without jacket-core separation.
