I love getting old enough to say things like

"Back in the day"... In the late 80's/early 90's I shot a PSE Mach Flight V. That beast was set at max and it was either 85 or 90 lbs. But that was when I was way younger, way stronger, and shot constantly.

After that, I shot a 70# recurve for several years with big heavy wood arrows, feather fletching, with a 160 gr broadhead. All that mass was slow, but it would penetrate like crazy.

Now I am shooting an Oneida Black Eagle set at 65#

Back to your question, minimum legal for deer in Oregon is 40# and 50# for elk. I would be comfortable with those, if I needed to go down to that. Of course, you are trading off a flatter trajectory by going lower.
