RE: Hevi-Shot vs. Magshock
The new federal heavyweights can be shot out of any choke. This is from the mouths of the techs at Federal. As far as pattering goes. Ive tested both the Mag Shok copper plated lead and the heavyweights out of a Full, Xfull , and XXfull choke. The copper plated lead #5 shot was the best pattern ive ever gotten out my gun. Averaged 25 in the vital head and neck areas at 40 yards with a very uniform pattern around that. I couldnt get the heavyweights to do as well.
