Product Advisement

This brass is sold as USED, RAW, DIRTY and contains cartridges from various commercial and NATO manufacturers; some of which may contain a crimped primer.  As of early 2022, we are seeing a small percentage (~10%) of IK21 headstamp (easily identified by its red primer sealant) which feature a smaller flash hole many reloaders are not familiar with.  These cases are perfectly reloadable, however we recommend the use of a tapered or small decapping pin.  If you have any concerns, please contact us before purchase.
