Forming some 300 Blackout brass
This video details a method for forming 300 Blackout brass from .223 Remington cases using a modified chop saw and a specialized jig. The process involves cutting the cases to a preliminary length, resizing them with a full-length die, and then trimming them to the correct 300 Blackout specifications. The instructor emphasizes the importance of proper jig adjustment and tool selection for achieving consistent results, while also demonstrating the subsequent steps of loading and testing the newly formed brass.
