Some of the finest lead loads ever made. Copper Plated Lead in grex buffer very tight patterning loads. Bob Brister wrote about these loads in his book Shotgun art and science. Use them on Pheasants where legal or Crows and other predators. In a light gun they will rock ya pretty good. Use to love those shell shot from a IC choked 870 very deadly. You might be able to use in Mexico or Argentina on waterfowl but no where in the USA.
