300 Winchester Magnum Brass – ADG manufactured brass is optimized not only for consistency in performance, but also for durability. One of the ways ADG accomplished this is by optimizing the material in specific areas to strengthen it. With the optimized material geometry, ADG 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. ADG recommends using a reputable load data source and working up from their recommended minimum starting loads.
ADG recommends 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.

ADG 300WM brass
I haven't loaded it up yet, but initial impression is very good. By all accounts, this is some of the most consistent brass you can buy. The annealing looks perfect, flash holes have no burrs, and the padded ammo box kept the necks from being dented. It looks like you would be able to just chamfer and debut the neck and load it, which is what I plan to do. I will be trying some of their brass in other cartridges going forward.
