Last fall, on a backpack archery elk hunt, I was 38 lbs including food and water, but excluding my bow and my bino harness. Including binos and bow I was closer to 48/50. This was for 4 days in second week of September in Northern/Central Utah. I was carrying about 2200 calories per day in food, and a 32 oz Nalgene and a filter (TONS of water in this spot). Was splitting camp with a guy I used to hunt with at the time, so add another couple pounds if I was carrying my own shelter 100%.
What I did notice was that food weighed about 1.25-1.5 lbs per day. So I had about 6 lbs of food. Outside my food and fluctuating water levels, my gear would've weighed the exact same whether I was hunting for 3 days or 10 days, the only variable being additional food. So straight up gear ends up being about 40-45 lbs, with food fluctuating depending on the trip length.
