I am well informed that "Turkey Rounds" is not the best name for these turkey feathers, but it is what most fly shops call them.
I find the feather barbule makes a nice dun abdomen. It is not too fuzzy like the fuzzy side of what is commonly called a "biot" feather, and not too smooth either.
This feather is a PMD dyed color.
