I shot my san juan bull in 2010 out of a tree stand. Pretty incredible experience. In the stand before first light in the morning with bulls bugling all around me on the way in up until 5:00 pm when after bugling all around me in the swirling winds all day, finally a great bull with 22" thirds came in and tore it up right in front of me on film !!!
It can happen. Spent a million hours in stands over the years and that's the one on a premium limited entry tag I've had happen.
Obviously YMMV when it comes to trying for big bulls from a stand.
