Caliber: 505 Gibbs Magnum
Due to the manufacturing process and/or shipping, case mouths may not be perfectly round. To ensure a round case mouth, cases must be sized (or have the expander ball of the sizing die run through case neck) and deburred/Chamfered prior to loading.
A light "staining" may be found on the case neck of new brass. This is due to annealing. Annealing is a process, performed by the manufacturer, which involves rapid heating to a specified temperature followed by rapid cooling. This process imparts cases with the proper hardness to securely hold a bullet as well as gives flexibility to expand and contract upon firing and repeated forming. The "staining" is a residue from this process. This stain may be removed by tumbling before loading.
SAAMI specifications: None, but claimed length is 3.15 inches.
This cartridge is also known as the .505 Rimless Magnum. It dates from 1910. This cartridge cannot be made by converting any other standard cartridge.
