.20 BR Load Data & Reloading Guide

The .20 BR, or .20 Bench Rest, is a precision rifle cartridge developed in the early 1990s, primarily for benchrest shooting competitions. It was created by wildcatting the famous .22 BR cartridge, scaling down the bullet diameter to accommodate .204-inch projectiles, which enhances aerodynamic efficiency. This caliber has gained popularity for its ability to deliver high accuracy and reduced recoil, crucial characteristics for competitive shooters.

Key technical features of the .20 BR include a case length of 1.460 inches with a base diameter of 0.434 inches, allowing it to fit in standard small rifle actions. It is typically loaded with powders such as Varget or Benchmark, which provide excellent velocity and efficiency. The caliber can push bullets at speeds exceeding 3,600 feet per second, depending on the load, resulting in impressive flat trajectories and minimal drop over distance.

In terms of bullet weights, the .20 BR commonly uses projectiles ranging from 32 to 50 grains, with options available for both lead and polymer-tipped designs. This versatility allows shooters to select optimal bullets for specific applications, whether for target shooting or varmint hunting. The caliber excels in precision-oriented environments, with its inherent accuracy making it a favorite among competitive shooters and avid reloaders alike.

For reloaders, the .20 BR offers distinct advantages, including the ability to fine-tune loads for specific shooting conditions and preferences. With a wide selection of bullets, cases, and powders available, reloaders can achieve high-performance loads tailored to their needs, ensuring consistent results on the range or in the field. The caliber's relatively low case capacity leads to lower powder usage per load, making it economical for frequent practice and competition.
