I’ve experimented with hanging times - everything from freeze within an hour or two if shooting and 12 days at 3 degrees.I’d be interested if the haunch of venison is a bit tenderer having not been frozen the same day as shot…..
I can’t honestly say I’m able to detect any consistent effect of hanging on the tenderness. Obvious effects of the age and sex of the beast, some effect of time of year and location, some effect of post death handling (time to retrieval and time to chill), possibly an effect of how quick death was and how far it ran.
My thinking is now that hanging is convenient, and does no harm. But it certainly doesn’t seem to improve anything.
