WC-860

WC-860 is a military-grade, large caliber ball powder designed for large-capacity rifle cartridges like the .50 BMG, providing high velocity and stable pressure. . It is a cost-effective option for high-volume production, known for its consistent metering in automated loading environments. Due to its bulk and burn rate, it's often a surplus product, with reloaders noting it burns cleanly near max pressure but can be sensitive to primer changes, and may be dense and require using data for similar powders like H870 for reloading
