7.65 French Long Caliber Brass Cases Starline 100 pcs

The Starline 7.65 French Long brass cases—also known in technical ballistics as the .30 Pedersen or 7.65×20mm Longue—represent an exceptional choice for precision handloaders and ballistic enthusiasts aiming to preserve and operate classic French military firearms with utmost reliability and accuracy. This historically significant cartridge, although scarce in contemporary commercial ammunition markets, was originally chambered in iconic French sidearms such as the MAS 1935 pistols and the MAS 38 submachine gun, both extensively utilized during the Second World War. Starline’s manufacturing excellence now allows reloaders to replicate the original ballistic performance using premium, new brass cases engineered to meet rigorous dimensional and metallurgical standards.

Comprehensive Reloading Procedure for Optimal Performance

These Starline brass cases are sold primed but uncharged and without projectiles, specifically tailored for experienced reloaders specializing in metallic cartridge assembly. The following detailed step-by-step guide ensures safe and consistent handloading results:

1. Initial Inspection: Conduct a thorough visual and tactile examination to confirm cases are free from cracks, dents, or deformities that could compromise chambering or ballistic integrity.
2. Case Preparation: Utilize a brass cleaning brush to remove any residual lubricants or oxidation from the case neck and body. Apply appropriate case lube if employing full-length resizing dies to prevent case sticking and ensure dimensional consistency.
3. Trimming to Spec: Measure overall case length using precision calipers. Trim cases exceeding maximum length specifications to maintain uniformity and prevent excessive chamber pressures.
4. Deburring and Chamfering: Remove any burrs on the case mouth both internally and externally using specialized chamfering tools to facilitate smooth bullet seating and prevent jacket damage.
5. Priming: Seat small pistol primers securely using a dedicated priming tool or press, ensuring proper alignment and seating depth to guarantee reliable ignition.
6. Powder Charging: Dispense propellant charges strictly following published load data for the .30 Pedersen cartridge, starting at minimum recommended powder weights. Incrementally adjust loads while monitoring for pressure signs and velocity consistency.
7. Bullet Seating: Insert projectiles to the precise overall cartridge length (OAL) specified for the firearm in use, ensuring optimal engagement with rifling and reliable feeding.
8. Crimping (Optional but Recommended): Apply a light roll crimp if the firearm’s feeding mechanism or recoil characteristics necessitate additional bullet retention to prevent setback or misfeeds during cycling.
