From what I understand, you want 100 to 120 psi. There's even kits you can buy for it with special needles to use for various game. Probably great for commercial processors, but I'd like to hear from anyone who's actually done it too...

I've been considering this process for a while, but haven't actually tried it yet. Mostly because I skin and quarter my deer while at camp, where I have no compressor (and only off-grid battery power). Also, because I only take a few deer a year - I think the real benefit here is volume, if you have a ton of deer to skin, you want to save as much time as you can.
