Executing a mixed-bag hunt in Argentina requires a strict adherence to ballistics, forcing hunters to constantly rotate between non-toxic steel #4 shot for morning waterfowl, standard lead #7.5 for midday upland perdiz, and light target lead #8 for high-volume afternoon doves.
The Ballistic Transition Strategy
The greatest mechanical challenge of a 3-species itinerary is ensuring you have the correct payload loaded into the correct gun. Firing a heavy duck load at a dove will destroy your shoulder, and firing a light dove load at a heavy-bodied pochard will result in a crippled bird. Because the outfitter provides all the ammunition on-site, you do not need to fly with these shells, but you must explicitly instruct your bird boy on what payload you expect him to load during each phase of the day.
| Target Species | Mandatory Payload Requirement | Optimal Shot Size | Standard Gauge |
|---|---|---|---|
| Ducks (Pochard/Teal) | Non-Toxic (Steel or Bismuth) ONLY | #3, #4, or #5 | 12-Gauge |
| Spot-Winged Pigeon | Lead (Heavy Field Load) | #5 or #6 | 12-Gauge or 20-Gauge |
| Upland Perdiz | Lead (Standard Upland Load) | #7 or #7.5 | 20-Gauge or 28-Gauge |
| Eared Doves | Lead (Light Target Load) | #7.5 or #8 | 20-Gauge |
| Monk Parakeet | Lead (Heavy Target Load) | #7 or #7.5 | 20-Gauge |
The Non-Toxic Legal Boundary
The most critical transition occurs between the morning and the midday shoot. Argentina law strictly mandates the use of non-toxic shot (steel or bismuth) in all wetland and aquatic environments. Using lead shot in a duck blind will result in the immediate cancellation of your hunt by the wildlife police. However, once you leave the marsh and enter the dry agricultural fields for perdiz or doves, the legal restriction lifts, and you transition back to traditional, highly effective, and much cheaper lead shot.
Tactical Field Note: Always verify the shell boxes in the field truck before you begin shooting. Bird boys work fast and can occasionally mix up flats of ammunition. If you are stepping into a pigeon blind, physically ensure the box reads #5 or #6 lead. Shooting at a heavy Picazuro pigeon with #8 dove target loads is a frustrating waste of time.
