RCBS Shell Holder No. 20 for Reloading and Shooting

Designed specifically for .45 Colt and .45 Casull calibers, this high-performance ammunition is engineered to deliver exceptional ballistic precision and reliable terminal performance. Utilizing advanced metallic and semi-metallic cartridge components, each round is meticulously crafted to optimize internal ballistics, ensuring consistent muzzle velocity and superior accuracy for both hunting and tactical shooting applications.

The cartridge case is constructed from premium-grade brass alloy, providing enhanced structural integrity and corrosion resistance, which is critical for repeated reloading cycles and maintaining dimensional stability under high chamber pressures. The projectile features a carefully engineered semi-metallic jacket that balances weight retention and controlled expansion, maximizing energy transfer upon impact while minimizing barrel fouling and wear.

Ideal for precision shooters and handloaders who demand meticulous control over powder charge and seating depth, this ammunition supports a wide range of propellant types, including smokeless powders optimized for clean burning and consistent pressure curves. The combination of robust primer ignition and uniform powder distribution contributes to reduced standard deviation in muzzle velocity, enhancing shot-to-shot consistency and overall ballistic performance.

Whether employed in lever-action rifles, single-action revolvers, or modern semi-automatic platforms chambered in .45 Colt or .45 Casull, this ammunition meets the rigorous demands of big game hunting, silhouette shooting, and defensive scenarios. Its design reflects a deep understanding of cartridge dynamics, metallurgy, and terminal ballistics, making it a preferred choice among experienced reloaders and professional marksmen seeking reliable, high-quality performance in the field.
