I would use an IC on the west side and probably modified or eastside with #4 shot. Hevi-shot works good. Expensive, but you typically only shoot a few shots to get your birds. Besides, the release birds seem to hold tighter than the wild ones. It also depends on the quality of dog you are using. I see a lot of house pet on the west side hunting for phesant and some great quality hunting dogs mixed in for fun.
