That seems pretty high if the carcass was already skinned and just to make standard cuts, but if it was a big elk it might be up there ? Salami, jerky, smoked hams ect. all are an upcherge usually. The shop I usually use for my beef is 1.80$ A pound Carcass weight to process wild game with a 180$ minimum charge
If I take deboned scraps he will grind into burger for 1.80 per pound and not charge me the minimum fee. I just picked up 56 pounds of elk and deer last night and it was only 93$ or so. I do this more for the convenience of not having to vacuum seal 56 packages more than anything.
Another thing I found this summer is Here on west coast butcher shops are slammed busy. I just got a steer butchered and processed 1.10$ lb hanging carcass wait but the problem is availablity. I had to schedule it almost 3 months in advance because they are so busy processing all the county fair animals that were sold private party due to COVID. I called every butcher shop within literally almost 100 miles to find one that would accept my steer sometime this year
the tricky thing is some meat processors still operate in an older business model where things are more verbal, handshake, assumed so you might not know what you are signing up for unless you ask the right questions at the beginning. I have dropped off game at shops before and my wife says how much is it going to be and I have no idea because I never thought to ask what costs what, is this or that cheaper , ect so now I always try to talk to butchers and say if I do this or that next time is that better for you , cheaper, better quality, ect
