Winchester 300 Blackout Brass

Cases are sourced from indoor shooting ranges and fully processed after inspection. Headstamps will be exclusively Winchester (even WCC will be pulled) from various years with the majority, if not all, having been converted from their .223/5.56 cases.  All cases have been hand inspected, wet tumbled, decapped, swaged, full-length sized, trimmed, mouth expanded, wet tumbled some more, and inspected again. We form our 300 Blackout brass with an initial sizing and rough trim followed by a shoulder bump and final trim to maintain the tightest of tolerances.   Cases are unprimed and ready for you to have your way with them. Pluck them one by one or drop them all in your case feeder.  Extra is always included, call it a "Reloader's Dozen."
