Baschieri & Pellagri 103 Pistol

B&P 103 Magnum Pistol is a smokeless handgun propellant produced by Baschieri & Pellagri (B&P), developed specifically for higher-pressure and higher-performance pistol and revolver cartridges. It is generally positioned in the medium burn-rate range, making it well suited for “magnum” applications where a progressive pressure curve, good case fill, and stable velocity are important. Typical use cases include powerful revolver loads and heavy-for-caliber handgun bullets where consistent ignition and efficient energy delivery help achieve reliable performance.

Compared with faster pistol powders, B&P 103 Magnum Pistol is designed to work effectively with larger charge weights and longer pressure durations, which can support higher velocities while maintaining controllable pressure levels when used with appropriate data. Many reloaders look for this type of powder when optimizing loads for cartridges such as .357 Magnum, .44 Magnum, .454 Casull, or similar high-energy handgun rounds, depending on published load compatibility.

Like any propellant intended for magnum-class performance, accurate charge measurement and careful load development are essential. Results depend strongly on case volume, bullet seating depth, primer choice, crimp strength, and barrel/cylinder gap in revolvers. B&P 103 is typically chosen by shooters who want repeatable ballistics, consistent shot-to-shot velocity, and dependable function in demanding handgun loads, especially for hunting or heavy-duty applications.
