I have a 55 pound keg of Maxam CSB-1 commercial reloading powder made in Spain. Use Universal data and work up from there. Ideal for Pistol or Shotgun reloading. Priced to sell at $20 per pound, for sale as full container only. Stored in climate controlled building since purchase from a commercial reloading company that closed down.

MAXAM CSB-1 is a single-base, disc/flake smokeless powder engineered for metallic cartridge reloading, with a focus on handgun calibers. Designed for regularity and precision, CSB-1 delivers low-residue operation and stable pressure behavior, making it a strong fit for high-throughput commercial reloaders and OEMs. Its clean-burning characteristics help minimize fouling and maintenance, supporting consistent output and reduced downtime in bulk pistol ammunition production.
