Not that long... What SE means to say is that the casings in a hank are in long continuous strands. The most recent hank I opened had 15-16 long casings in it...tied to a plastic ring with the size marked on it. some of the casings were too long to all fit on the stuffer horn so I had to cut it.A hog will have a single 100 yd intestine? Why don't you tell me where you get yours, then I can be sure to get some quality casings.
