With a tapered, precision-drawn jacket and a long nose, the Grand Slam®  bullet is engineered to blow through the thick hides, heavy bones and  tough bodies of the world’s biggest game—without sacrificing accuracy.  

On impact, internal jacket flutes allow consistent expansion, yet the  bullet retains most of its weight for deep penetration every time.  This bullet would make a solid choice for all big game, including those that bite back, when hunting at normal hunting ranges.  

We measure each powder charge to within +/- .02 grains on our Autotrickler powder systems.  We seat each bullet with Redding competition seat dies on our Forster Co-Ax single stage press.   We load them one at a time!  Each round is hand measured for consistency and placed into our hard plastic, twenty count boxes.  Each box has a foam insert and neoprene strap to keep your rounds secure in the field.  This is loaded ammunition.  

Also available for $80/Box of 20 when choosing our cosmetic blem brass option.  Same great brass, just not as shiny and pretty.  Ask at time of ordering.
