.264 (6.5 mm)

Hammer Bullets® produces .264 caliber bullets for hunters using 6.5mm rifles who need a high-performance hunting bullet for medium to large game. Each bullet is turned on a Swiss-style CNC lathe from pure copper, then weighed and micrometer measured during the production run. With no lead core and no jacket, a Hammer bullet maintains its one-piece construction and expands reliably across a wide window of impact velocities.

The 6.5mm is popular among hunters and shooters who want flat trajectories, efficient performance, and long-range capability. Hammer takes a different approach by using pure copper construction to create lighter bullets that maintain deep penetration and reliable expansion for big game hunting applications.

The case for a heavy 6.5mm bullet is familiar. High BC projectiles retain velocity well and reduce time of flight at distance, which can help limit the effects of wind. However, BC is only one factor in long-range performance, and retained energy alone does not determine how a bullet performs on game.

Copper shifts that tradeoff. Without a lead core, a lighter Hammer bullet can achieve higher impact velocities while still providing deep penetration and controlled expansion. Shooters can reduce bullet weight, increase velocity, and maintain effective terminal performance.

Heavier options are covered as well. Shooters building rifles around longer projectiles and higher BC will find .264 bullets designed for those applications, so the lineup serves both approaches.

Every Hammer bullet carries the patented PDR bearing surface, which reduces the amount of bullet material contacting the rifling. Instead of a full-length bearing surface, PDR uses small drive bands that engage the barrel while allowing space between them for displaced material.

Less contact means less friction and lower engraving pressure. This allows Hammer bullets to produce higher velocity potential at similar pressures while reducing copper buildup compared to traditional designs. The design also helps bullets seal properly across different bore sizes, maintaining accuracy without pressure issues.

The PDR design makes load development more forgiving by reducing sensitivity to seating depth changes. Less adjustment is often needed to achieve consistent, accurate results.

Copper does its own thing at the loading bench. Data written for cast bullets or conventional jacketed designs will not map directly onto a monolithic bullet, even at the same weight, so use Hammer specific load data whenever it exists.

Seating depth can influence accuracy, but Hammer bullets are designed to be forgiving during load development.
