I'm trying to load some 32/35 mm hog casing onto my 30mm stuffer funnel. I can only get the first inch or two then the casing starts tearing. I even tried loading it onto a 20mm funnel, same problem. The casing just stick and hang up. I soaked them for a good hour and rinsed them several times. I also rinsed the inside. Can anybody shed some lightt on this??.
