My favorite packs in that range are not hunting packs. The North Face Terra 35 and (now discontinued) Kelty Pawnee 40. My current pack in that range is just a little smaller than you're asking about, Mystery Ranch Scree, 32L. It's pretty new to me so I won't mislead you with glowing recommendations, but so far, it's done everything I've asked of it nicely. That doesn't include climbing 19,000 foot mountains though.
