First what is your budget? Second how tall are you? These questions will narrow down the search.
When I was looking for my first pack for elk hunting I would have loved to purchase a Kifaru or Stone Glacier etc. But I was gearing up for both my son and I so expenses on equipment was multiplied by 2.
After a lot of research and calls into Mystery Ranch I bought two MR Glaciers from their backpacking line. Why? Because after speaking with MR customer service they told me it was rated for 100lbs. This is about double the limit of most backpacking packs! The Glacier is about the same size as the Metcalf from the hunting lineup but IMO it has much better organization. So the only thing I gave up was a meat shelf and 50lbs carrying capacity. I added a Kifaru Grab it so I could carry some of my stuff between it and my pack bag if we were lucky enough to get one we would put the quarters in the bag. I trained with 75lbs and it handled it so well I am confident the 100lb rating is light. The only issue is if you have a long torso. I have a 21” torso and I would say that would really be the max. My son is 6’5 with a 23” torso so the load lifters are even with his shoulders. That limits the weight he can carry comfortably.
Just a little over a month ago I bought a 2019 MR Terraframe 50 and it has the meat shelf and is rated for 150 lbs. It carries even better than the Glacier and I can say first hand it will handle heavy weights easily having packed about a 120lb doe a few weeks ago out whole. I got it from Sierra.com for $229.00. I can get everything I would need for 3 days inside and if I wanted to stretch to a week I would put my sleeping bag in a dry sack and strap it on the bottom.
