.22 Hornet (Cast Bullets)

The use of cast lead bullets in the .22 Hornet offers a low-cost, forgiving alternative to jacketed bullets, especially for small game and target work at shorter ranges. In Handloader Issue #130 – November, 1987, the cartridge’s performance with cast bullets is discussed in depth—with load tables, bullet alloy considerations, and behavioral observations under field conditions.

The article evaluates several cast bullet weights typically ranging from **35 to 45 grains**, often utilizing soft lead alloys (e.g., 1:12 to 1:16 tin-antimony blends). Because cast bullets engage the rifling differently than jacketed bullets, careful design of the bullet’s diameter, hardness, and lube scheme is essential. These bullets tend to use lower velocities to avoid leading, typically in the range of 1,800 to 2,600 fps depending on barrel length and bullet alloy.

Load data in the publication shows conservative powder charges using propellants like IMR 4227 or reduced charges of more commonly used Hornet powders, tailored to avoid excessive pressure or leading. The article also covers the importance of bullet lube — both type and amount — and proper sizing to reduce leading, accuracy loss, and rapid throat wear. Some loads with cast bullets showed acceptable groups with reduced fouling when bullets were sized to just touch the lands without excessive seating pressure.

Notable observations include that cast bullet accuracy tends to diminish with barrel heating, as soft bullets may upset or deformation may begin. To mitigate this, the article recommends possible throttling of velocity or periodic cleaning. Also, cast bullet loads tend to be more forgiving in terms of seating depth variance, as soft bullets can more easily conform to slight seating inconsistencies, though this is balanced by the risk of “overjump” effects in some rifles.

Though cast bullet loads do not compete with high-BC jacketed bullets at longer ranges, they remain practical for economical varmint practice, plinking, or situations where minimal cost is paramount. For shooters working older Hornet rifles or those favoring gentler recoil and component reuse, using cast bullets with care can keep the legacy of the Hornet alive without sacrificing the skill of load development.
