.219 Donaldson Wasp Load Data & Reloading Guide

The .219 Donaldson Wasp is a wildcat cartridge developed in the 1930s by Harvey Donaldson, a renowned American gunsmith and target shooter. Originally based on the .219 Zipper, the Donaldson Wasp was designed to improve upon its parent case by offering superior accuracy and a relatively flat trajectory for small game and varmint hunting. This cartridge gained popularity among precision shooters and reloaders for its performance and customizability, despite never being adopted commercially in mass production.

One of the key technical characteristics of the .219 Donaldson Wasp is its case design. The case retains the same rim diameter as the .30-30 Winchester but features a more pronounced shoulder and reduced taper. This reshaping contributes to better case life and consistent chambering, which are highly beneficial for reloaders. The cartridge typically fires .224-inch bullets, with common weights ranging from 40 to 55 grains. Such variability allows enthusiasts to tailor loads for specific uses, from shooting at short ranges with light projectiles to longer distances with heavier bullets.

Ballistically, the .219 Donaldson Wasp is lauded for its impressive velocity and accuracy. With muzzle velocities typically ranging from 3,000 to 3,500 feet per second, depending on the bullet weight and powder charge, the cartridge is well-suited for varmint control and competitive target shooting. Its relatively mild recoil also makes it a favorite for benchrest competitions. Moreover, the cartridge's performance at moderate ranges ensures shooters can achieve consistent groupings, which is particularly appealing for those who engage in precision shooting.

Reloaders appreciate the .219 Donaldson Wasp for the flexibility and customization it offers. The wildcat nature of the cartridge means many components are not factory standardized, providing the freedom to experiment with various powders, primers, and bullet weights. This adaptability can result in finely tuned loads that maximize accuracy and performance for specific rifles or shooting conditions. Additionally, its efficient use of powder and minimal case stretching supports prolonged case life, allowing reloaders to achieve multiple firing cycles with careful maintenance.
