Breeze set his record with four Winchester Super X3 20 gauge semiautos. He had two loaders working and they used three guns with a fourth as a backup. Breeze had tried other brands of guns and been frustrated by failures to fire with the Argentine RD or Fiocchi ammo that is not as reliable as the stuff we get in the U.S. Winchester did supply him the guns, but that doesn’t change the fact that they worked very well indeed for him, as his record attests. Being 20 gauge gas guns they did not kick much, and just as important, they were light.
