You're going to need at least a couple trips in if you don't have gear drop-camped. I just returned from a trip backpacking in MT and for two of us to go in for 3 days with everything we needed to camp, hunt, and responsibly process a bull was quite a bit of weight. Granted we were going in Nov so we had extra gear I would not take on a Sept hunt (got VERY cold on us).
For certain, get the lightest tent/stove etc you can, you WILL notice ounces pretty quickly.
