You betcha! Howled one in last time I was out, about 10 days ago, on the second set. Never touched the distress call at all, not even the squeaker until it closed the 400 yards from when I first saw it to about 30. At least out here in the west, howling works all year for me... especially from early evening (the golden hours until dark) to a couple of hours after dawn (the pre dawn on silver hours). I always do howling first and then the distress only if needed, and use my mouth calls only.
