X12X Symmetrical Gas Seal (250/bag)

The X12X is our best-selling gas seal and holds the top spot for its exceptional performance in sealing propellant gases. Our lab has yet to find a gas seal that surpasses the X12X in terms of efficiency and effectiveness, even with the slowest burn-rate powders. This seal ensures highly efficient powder burn cycles across a wide range of powder types.

Widely adopted by high-specification cartridge manufacturers, the X12X serves as the primary wad in high-performance ammunition, including those used in law enforcement and military applications across all weather conditions. Its symmetrical design simplifies the loading process—there's no need to orient it in any specific direction. Additionally, the X12X excels in sealing gases for both slow and fast-burn-rate powders, making it a versatile and reliable choice for various applications.
