No way to tell how many pellets were in it. The head, neck, and back of the turkey had plenty of holes. It 2002, the shot was across a pasture, from under an oak we were both sitting against, on a partly cloudy Thursday afternoon, light breeze, about 64 deg. F, 8mph WSW wind.

I have no idea. He's usually pretty good about getting them close.
