In the wind with 39/40's, the 204 is pretty awesome in a dog town; they don't seem to unglue them as well as .224's and definitely not as well as the .224's and .243's that are in the same speed zone.
Still a very good choice and easier to hit with, drop and windage wise, over std. twisted 222's and .223 class cartridges and better than 17's in my book.
