The Lyman Custom Fit Loading Block .388 Hole Size is a precision reloading accessory designed for handloaders who require organized and efficient ammunition preparation. This loading block is specifically tailored for .38 Special, .357 Magnum, and other related centerfire cartridges that fit within the .388-inch specification. It holds 50 rounds securely in indexed positions, making it ideal for competitive shooters, law enforcement armorers, and serious precision reloaders.

Constructed from tough, durable polymer, the Lyman Custom Fit Loading Block is designed to withstand repeated use and harsh workshop environments while remaining lightweight at 0.35 lbs. The .388-inch hole size ensures a precision fit for compatible cartridge families, preventing rocking or shifting, which is critical for maintaining consistent powder charges and bullet seating depths. The block's design streamlines the staging process, allowing for efficient organization during reloading.

Reloaders preparing ammunition for .38 Special, .357 Magnum, and similar cartridges will benefit most from this system. The loading block allows for staging cases for depriming, priming, powder charging, and bullet seating in separate blocks, effectively preventing cross-contamination. Additionally, the blocks nest together seamlessly for convenient storage and organization of multiple calibers in a compact space.
