The 2200 is enough for 3-4 days of hunting. You should be able to carry about 50 lbs. of meat without too much discomfort. I don't own one, but my brother has one and has hauled both deer and elk meat with his. He's had it for years, and I'm sure the design has changed since then. I use a 3300 from kelty, which has hauled a lot of gear and meat for me. It's light, simple, and made with quiet camo material. I also have a 2400 from kelty that has seen better days from a lot of use, but has hauled more pounds of meat than any other pack I own. I used to use it for bivy trips up to 3 days. I've found the 3300 to be a bit more suited to stays longer than a few days. I've never found a reason to go beyond that size for the type of backpack hunting I do.
