300 AAC BLK Brass Made From Once Fired Military Brass Partially Processed - Sample Pack - 100 Pieces
This is a sample pack of 100 piecesof
300 AAC Blackout brass that is partially processed.
We are so busy dealing with our 5.56 and 7.62 that we have decided to offer this brass in this phase of production. Normally we only sell fully processed for this caliber. This
partially processed 300 AAC Blackout brass
has been polished but may have primer pockets that have not been cleaned as usually the first polishing is done with the primer in the case. It has then been
processed to an
that includes removing the primer and swaging the primer pocket. The case is trimmed to around 1.36 inches in overall length and still needing touched with a full length sizer for final sizing. It is not final sized but quite close. This brass is converted from predominantly Lake City, but will also contain other government contract brass.
The sample pack does not ship in one of our wood boxes.
This brass has most of the hard work of converting it done. Good for those who want to save a few dollars by doing it themselves or want to size just right for a specific rifle.
