I'd venture that almost all hunters would use suppressors if they were legal.
Hunters go to great lengths to reduce the ability of wildlife to detect them (see, smell, or hear) - we buy camo so we can't be seen and scent protection to prevent being smelled. You stay as quiet as you can while walking through the woods. There is a huge difference is how long it takes the woods to return to "normal" if I shoot my bow, .22, or 25-06.
Doesn't matter that suppressors aren't really silent - I'm sure I still stink some when wearing scent protection. Hunters will buy anything that gives them even the perception of an "edge".
