ADG 7 SAUM (Remington Short Action Ultra Magnum)

Description

7 SAUM (Short Action Ultra Mag) – ADG manufactured brass is optimized not only for consistency in performance, but also for durability.  One of the ways we accomplished this is by optimizing the material in specific areas to strengthen it.  With the optimized material geometry, our brass will generally have a different case volume than most other manufacturer’s brass and therefore will require a different charge weight to achieve the same pressures and velocities.  We recommend using a reputable load data source and working up from their recommended minimum starting loads.

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.  You or your gunsmith can purchase the reamer directly from JGS Precision using the following part number.

We recommend reducing any existing charge weights by 10% and re-developing your specific load when replacing any component in a load recipe with a new component (brass, projectile, primer, or powder type).  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.
