375 Rem Ultra Mag Brass – 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.
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.
Available in our standard finish with the anneal line visible or our bright finish that has had the anneal line polished off.
