I lived in Alaska for a few years while I was in the Air Force, hunted a lot but never drew a tag for the Fort Richardson hunt for moose. My friend did, and he made the best of it...
Have a pic to post here, but he did use a compound so I won't... 46" bull, perfect 20 yard double lung shot. But, we saw a lot of different moose while hunting snowshoes and spruce grouse. I only wish I could have drawn a tag... stalked many different moose, bulls, cows, and calves. Would have loved to put an arrow in any of them.
Although his was some very good eating, I would venture to guess younger is better table fare given it is with whitetails... you did good! Especially since it was rifle season when you did so. Critters don't act themselves when they are being pressured as they are during any rifle season.
