My pet pheasant load in 16 gauge is:

Old WW compression formed hull
AA16 wad
WW209 primer
18.8 gr/WSF
1 1/8 oz magnum #6

I have a stash of the older components, and make no recommendations of interpolation with other hulls and wads.

These function extremely well, work in very cold weather, throw great patterns in my guns. Check available data independent of this; this is just what I use and have been successful with.
