A guy i work with has been down there a couple times . The pictures i have seen would be unbelievable if i didn't know him so well.I've been tempted to book a trip down to Argentina but I don't know if I could sustain 3000-4000 shots a day down there.
Other than that I haven't been dove hunting in years. A area that I lived in Utah held doves but by the time September rolled around they were already headed to Arizona and warmer climates.
Try the Federal #7 shot, can’t remember the name But they sell them at Wal-Mart and they are 1400+ FPS.Last year was the 1st year we had to use steel. Think they are hard to hit with lead, the steel will really humble you. Had to go from #8 shot to #6 steel. On the opener I knocked down 3 or 4 with 8’s and they got up and flew away before the dog could get them. Had to switch to #6’s with higher FPS in order to kill them.
