300 Rem Ultra Mag


ADG Remington 300 Ultra Mag Brass is designed for those who want to take the perfect load in their own hands. The 300 RUM is THE most effective casings for long range hunting. ADG’s RUM brass is able to seat the same weight or slightly heavier bullets than the 300 Win Mag. Packing a huge wallop, 32 foot-pounds of recoil energy in some cases, packs quite the punch and allows for a flatter trajectory and superb shot placement. Don't sacrifice performance, ADG's bolstered material in specific points is ideal for optimum case life and reloadability. Sold in a 50 count flip top case that doubles as a carry case for your reloads.



Important Safety Information:



With 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
