ok so I tried my hand last night at snack sticks. I was using a 21 mm casings that came with the seasoning kit and was using my Cabelas Jerky Blaster with the small single tip. Ok now for my questions 1. how do you easily load this thing without getting air pockets in it. 2. should I be able to just slide the entire casing on the tip?? I had to open it up and slide it on cause the casing had a only about 1/4" hole in the middle when it was all bunched up?? Thanks guys, Sticks are stuffed up, sat overnight in the fridge and will be going in the smoker once they warm up.
