Woods, you seem to have a nice way of getting the steel wool all neat and together to use. I struggle a bit, is there a bronze bore brush under there, or other secret you are willing to share?
Yes there is a 22 cal bronze brush in the middle of that gob of steel wool. I pull the steel wool off in long strings and wrap it round and round the brush. It will compress and I have to keep adding layers. When switching calibers I have to adjust the diameter, either by pulling some off or adding another layer or 2. I feel I am getting the best results when the steel wool is so tight it makes the Zip Trim hard to spin.
One advantage of the Zip Trim is that it holds the case firmly and gives you good leverage for working on the case.
If the interior of the neck is really rough like after turning or reaming, then I take a small strip of scotchbrite and hold it with some hemostats to begin the neck smoothing process.
