.22 Hornet Cast Bullet Loads

.22 Hornet Cast Bullet Loads

The “Cast Bullet Loads” feature in Handloader Issue #55 – May, 1975 highlights reloading recipes and observations specifically for cast lead bullets in the .22 Hornet. This article focuses on balancing lower velocities and pressures with good accuracy and minimal barrel leading—ideal for economical varmint or small-game shooting.

Using a range of soft, lubricated cast bullets (typically in the 35- to 45-grain range), the load tables pair those projectiles with mild charges of powders like IMR 4227 and W-296. The recommended starting charges are conservative, emphasizing slow progression and steady chronograph reading to avoid overloads, especially in vintage or lightly built rifles. Some loads approach but do not exceed moderate pressure zones, preserving barrel and brass longevity.

One of the key takeaways is the impact of bullet alloy hardness and lubrication on group size and fouling. Softer alloy bullets with fuller lube grooves showed better accuracy in the test rifles, and heavier lubes or thicker lube coatings helped reduce leading, particularly in warm barrels or extended strings. The testers also noted that slightly deeper seating (reducing bullet jump) sometimes improved groups, but excessive seating depth risked pressure spikes with cast bullets.

While the velocities achieved with cast loads are naturally lower than jacketed bullet equivalents, the article shows that well-tuned cast loads remain accurate and effective for practical field use. The lower velocities also tend to reduce barrel wear and recoil, making them appealing for frequent shooting or economical range use. For those working older Hornet rifles or using lighter build actions, cast bullet loads remain a viable and enjoyable option when developed with care.
