Northeast premium processed 300 Blackout brass is now in stock and ready to ship!  We are very particular about the 5.56 brass we use to make our blackout, there are only certain headstamps that will convert properly and then feed reliably in rifles.  We have several law enforcement accounts that produce a mix of Federal, Lake City, Remington, Winchester, and PMC.  We know these stamps all make excellent quality 300 blackout brass but we only recieve them once per year after qualifications so we can only produce limited amounts.  If we used our standard mixed stamp .223/5.56 we could produce endless amounts of 300 blackout but the quality of the final product is not the same as the previously mentioned headstamps. We will never sacrifice quality in an effort to produce more.  This material was washed, deprimed, resized, swaged, trimmed, and necked down to 30 caliber.  We then run it a second time to swage again and to flare the case mouth before the final wash and polish.  Tremendous care and labor went into making this brass, no shortcuts, no corners cut, the final product speaks for itself.

As with our Premium processed .223 Remington brass, this material has been swaged twice to ensure military crimped primer pockets have been properly removed for more reliable primer seating.  We found that while a single pass and single swage was fine for 99% of our customers, those using softer primers like Federal were experiencing more than usual crushed primers.  After having spoken to them and finding that a soft primer was the common thread in each issue, we decided to just double swage all of our 300 Blackout brass.  We have gotten excellent feedback on this brass and repeat purchases have been the norm.

As with all blackout brass you should always crimp the bullet in place to ensure reliable feeding.  If the case mouth is still flared after loading, you might have chambering issues.  If anyone has questions, feel free to reach out to us!
