DEFIANT MUNITIONS uses premium Lapua brass for all .223, 7.62x39, .308, .30-06, .338 and 6.5 Creedmor caliber ammunition.

All other rifle ammunition uses a proprietary, TPD plating giving 5X the lubricity compared to non-plated brass. This corrosion resistant plating won't crack or flake, like nickle plating can, and improves extraction and ejection of spent brass.
