Roger,
Do they cut good for you with no salt in them? I was always under the impression that the salt helps the tails split better when cutting. I used to dip tube and cut tails, but used salt. Thinking about either shooting or dipping tubes again, and if I can avoid salt, I will. It was my experience that the tails didn't cut well regardless of how I did it. Would almost be worth it to dip my tubes and pay someone with a hydraulic cutter to finish them.
