I have been privileged to hunt a long time in BC & Alberta.
Mulies, Whitetails, Blacktails, Moose, Elk and Caribou have all seen plenty of time on our table.
All deer are great table fare except in the rut.....I do not care for them at all then.
Elk is #1 as far as I am concerned. Moose [particularly a young one] is close behind.
The rest are all fine, and I really cannot state a preference. [OK, possibly the blacktail would win, lol]
But it definitely IS true that feed makes some difference. I have shot a number of mulies in sagebrush country.
And you can tell when you cook and eat it, but I definitely do not find it strong, just noticeable.
Care of the meat once the trigger is pulled is of paramount importance if you want prime table fare.
