The only "hunting" pack I'd consider is Kifaru. It's the only pack marketed to hunters that allows a custom fit to the back when using the aluminum stay option. It's available in three torso sizes.

Otherwise, find a used, pre-2008 Arctery Bora 80 or 95, a used Dana Design Terraplane or Astralplane, or a pre-2000 Osprey Silhouette or Zenith, or a 1990's Mountainsmith.
