ADG 7-300 PRC (Precision Rifle Cartridge) brass is a popular wildcat cartridge that we have started to produce as part of our standard caliber lineup due to demand.  It is simply our 300PRC cartridge further reduced to 7mm during the production process.  For the complete package, check out our ADG 1-1/4″ Fat Boy Series Sizing Dies.  They will be available soon for 7-300PRC.

As with all ADG brass, it is specifically designed not only for consistency, but for durability.  One of the ways we accomplished this was adding material to the case in specific areas to strengthen it.  With the additional material, our brass is heavier than most other manufacturers brass and therefore will require lower charge weights to achieve the same pressures and velocities due to the reduced volume inside the brass.  We recommend using a reputable load data source and working up from their recommended minimum starting loads.  Failure to reduce charge weights established using other manufacturers brass may result in higher pressures and velocities while using ADG brass and may result in unsafe pressure levels.

For the best performance and life from your ADG brass, we recommend using our optimized chamber design in conjunction with specifically designed ADG Fat-Boy Series full-length resizing dies.  For those who want next-level performance, we would also recommend annealing between loadings.  Annealing is not required to get ADG brass to perform better than our competitors, but if you are planning on setting world records, becoming a world champion, or stretching the legs on a hunt, absolute consistency is achieved when annealing the case mouth between firings using our ARC Ultimate Annealer!  ADG chamber reamers can be purchased at JGS Precision.  The ADG chamber meets SAAMI dimensional criteria and uses a SAAMI minimum freebore length.  The reamer design will be available soon directly from JGS Precision, part number coming soon!
