When I'm on an elk backpacking trip and cleaning and hauling meat can take days, caring for the meat can consume a large portion of the hunting season. Not to mention it avoids any issues of who might hunt a better area whe you're together. I've far more often shared meat from an animal I killed than the other way around, and I'm good with that. That's also the way my dad did all his moose hunts, and I stuck with it.
That said, for small animals (deer or antelope) I can certainly see why others might do it differently.
My brother once spent most is his elk season helping to haul a partners elk but wasn't offered any meat at all. Not a person he'll ever hunt with again, and I can see why.
I think as long as everyone is clear in things it should work out.
Good thread.
EDIT: I don't want to exaggerate. One style of hunt I've done could take 2 guys two long, full days (a couple of thousands of feet of elevation gain/loss across several miles on each trip). More lately, the elk hunts I've been doing might simply consume one full day for two guys as we've learned of an option to call the calvary (horses) to help. In the situation with my brother, he spent the last 2 days of his season, foregoing an ability to shoot an elk "of his own" to help his hunting partner. Figured I should be clearer since I said "days" above which isn't always the case. I guess the key for me is that these folks are my hunting "partners" vs. people simply on the same hunt. I fully respect that others may do things differently, and I suspect the key to all being satisfied is knowing the arrangement in advance.
