.218 Bee (P.O. Ackley Data)

P.O. Ackley’s work with the .218 Bee reflects his deep interest in wildcat ballistics and cartridge efficiency. Using the .218 Bee’s rimmed bottleneck case as a foundation, Ackley explored tailoring neck dimensions, shoulder angles, and body taper to improve performance, especially in older single-shot and lever action rifles. His efforts aimed to push the cartridge’s accuracy potential while maintaining manageable pressures and recoil.

In Ackley’s data, bullets in the 35- to 50-grain range are typical, with lighter hollow-point or tip-varmint types favored for flatter trajectories and faster expansion. For shooters looking for stability in wind and better ballistic coefficients at longer ranges, heavier 46- or 50-grain match or round-nose bullets are included in the load spectrum. Ackley’s notes also cover variations in barrel length—often 22 to 24 inches—and twist rates suited to those bullet weights.

Powders recommended in Ackley’s tables are those that burn cleanly and fill the case well without pushing pressures too high. Options such as H4227, IMR-4227, and benchrest style powders are frequently mentioned. Ackley emphasizes careful seating depth, neck tension, and brass preparation — especially important in a rimmed case like the Bee, where concentricity and consistent neck thickness affect performance significantly.

Ackley’s data also acknowledges the trade-offs: pushing performance comes with increased barrel wear, throat erosion, and the need for more frequent cleaning. But he frames these not as deterrents but as realities to be managed. Many handloaders following Ackley’s prescriptions report that the improved Bee variants produce tight groupings and reliable performance at varmint ranges up to 200-300 yards when loading with one’s own rifle in mind.

Though the .218 Bee never achieved the widespread commercial use of some rimless cartridges, Ackley’s version helped preserve its relevance among precision shooters and hobbyists. The wildcat is noted for its balance: excellent speed for its class, very manageable recoil, and strong terminal effect on small game. Reloaders who handload with Ackley’s data often find a sweet spot where efficiency, accuracy, and durability come together.
