Red, when you feel the auger starting to hang up, take all the pressure off, and even give a little lift to finish the hole. I have a 8" hand lazer, and it will hang up at the bottom of the hole also if you dont take some pressure off. I have a 10" Jiffy chipper, so I know what your talking about. You just need to drill more holes, and get the "feel" for when its ready to break through.
