Wild Hog is NOT the place you want to mess around cold smoking without Cure#1. IF you can't keep your smoker at <40°F add the proper amount of Cure #1, period, don't do it any other way.There are a whole variety of bacteria and viruses that can be on wild hogs that are not an issue with commercial pork.
Either Hot Smoke, 225°+, until the IT reaches 155°F or add the Cure #1 and Cold Smoke, ambient to 170°F, until your desired IT. If you freeze and will ALWAYS cook the cured sausage before eating, you can smoke and leave raw. If you or others want to eat it without further cooking, smoke to 150° first and freeze...JJ
