We have been shooting all 12 gauges shotguns mostly Browning 725, Krieghoff K80, Browning Cynergy, Browning 525 and Blaser F3. Our shells were local brand RD and ammunition # was 7 or 7 and a half; there was not a single issue with the shot guns, and we had clean the completely every day as we always do.
The total number of doves for the group was over 16,000 thousands birds, which made the trip amazing besides Alex did his own record on birds and shells.
