What are peoples favorite shotgun cartridges for rabbit, hare & pigeon?

[Big Dog]

I favor No.6 Highbrass for the small rodent types (squirrel, bunnies, etc.), though nowadays I've been using .22 rimfire.
No. 7 1/2 shot is favored here for doves and quail.

Rabbit and hare No.3's, it does the business. Pigeon no. 6's, quail 8's or 9's and duck's no.2 steel.
