About .20 VarTag

The .20 VarTag is a small-caliber centerfire cartridge that originated in the late 1960s, developed by the American gunsmith and wildcatter, John M. "Jack" Varminter. It was created primarily for precision varmint hunting and offers a high-velocity alternative to traditional varmint cartridges. The design features a compact case, which maximizes velocity while minimizing recoil, making it particularly favorable for shooters seeking accuracy at extended ranges.

Key technical characteristics of the .20 VarTag include a case length of approximately 1.25 inches and a neck diameter of 0.20 inches, allowing for optimal bullet seating. The cartridge typically accommodates bullets in the weight range of 32 to 50 grains, which contributes to its flat trajectory and allows for effective vaporization of small game with minimal meat damage. The .20 VarTag is known for delivering impressive muzzle velocities, often exceeding 4,000 feet per second, resulting in a trajectory that is both consistent and predictable.

In terms of ballistic performance, the .20 VarTag demonstrates excellent wind drift resistance due to its high ballistic coefficients. This capability enhances accuracy in varying environmental conditions, making it ideal for competitive shooting and long-range varmint hunting. Reloaders appreciate the cartridge for its flexibility in tailoring loads to specific applications, balancing between speed and accuracy.

Typically, the .20 VarTag finds use in varmint hunting, silhouette shooting, and precision target shooting. Its small size, combined with the high velocity and relatively low recoil, allows shooters to maintain accuracy and control even during extended shooting sessions. The cartridge's design also provides room for reloaders to experiment with different bullet types and powder charges, enabling them to customize performance for specific hunting situations or shooting disciplines. Overall, the .20 VarTag stands out as a powerful, versatile option for reloaders looking to optimize their ammunition for precision and effectiveness in the field.
