You've got my attention with this. What method would you recommend with the stipulations that the bone stays in so I have something to tie to, you end up with two matched sets of meat (front quarter x front quarter and hind quarter x quarter), and is quicker than my old school method? At 9 miles from the truck, in ruff country, and no one else to help me, I'm only making one trip.
I can only make the assumption you are in with a least a lead horse and 1/2 pack animals. I'll caveat this with if I'm packing out with a string I always have a lead and 2 pack animals at a minimum. My technique (when terrain allows)
1: Skin down the back, both back straps off, halved and put in gallon zip bags (open to cool while I'm breaking down the rest.
2: Skin and remove a front and rear quarter, bag and hang. ( Caveat I hunt in the timber a lot so 8 times out of 10 I have a branch/tree to tie off to and acts as my second person)
3: Neck meat off from the same side.
Wash, rinse repeat other side. Exception is I may saw off below the knee joints for ease of roll over first.
4: After all the above is done tenderloins out from behind the last rib.
Not saying its quicker at all. I'm personally not gonna expose spinal fluid or cerebral fluid on any meat I wanna get out and or haul the hide/skin unless getting it tanned.
How come the stipulation on bone in? Just for tie off to the pack saddle?
Flip side of all this. If its coming out on human backs I do the same thing
