# 1 Get "extended" chokes

# 2 You will need at less three (3) different ones to hunt all the game you mentioned.
Wide pattern = cylinder, improved cylinder or skeet
Average pattern = light modified, modified or improved modified
Tight pattern = light full, full or extra full (turkey)

# 3 You need different ammo for each type of game (ie: high # like 8 for small birds and lower # like 2 or 4 for large birds)

Note: steel shot is required for most waterfowl and you normally move to the next wider choke with steel shot (NEVER use full chokes with steel shot !!!).

That's the basics..................................
