Baschieri & Pellagri 109

Baschieri & Pellagri (B&P) 109 is a smokeless handgun propellant designed for high-performance pistol and revolver applications, especially where heavier bullets and higher energy levels require a progressive, controlled burn. It is generally positioned as a slower-burning pistol powder compared with standard fast powders used for light target loads. Because of this burn profile, B&P 109 is typically associated with “magnum-style” performance, where consistent ignition, good case fill, and a smoother pressure curve can help achieve stable velocities and reliable results.

Reloaders often look for powders in this class when working with powerful cartridges such as .357 Magnum, .44 Magnum, .454 Casull, or similar heavy-duty handgun rounds, depending on published load data and component compatibility. Slower pistol powders can be advantageous in these cartridges because they allow for larger charge weights and a longer pressure impulse, which may improve efficiency in longer barrels and support higher velocities with appropriate bullets.
