Smokeless Powder, Primers, and Fuses ship from our warehouse with other products. While Black Powder ships from our warehouse, in most cases it must ship by itself, therefore it incurs a separate shipping charge. Each order is limited to no more than 20 pounds of Black Powder, and no more than 66 pounds each of Smokeless Powder, Primers, or Fuse. Smokeless Powder, Black Powder, Primers, and Fuses are considered hazardous materials, incur HazMat Charges, and can only ship ground freight within the continental U.S. Due to safety considerations and legal/regulatory reasons, Smokeless Powder, Black Powder, Primers, and Fuses cannot be returned.
