To expand cartridge case mouths, Redding makes a Tapered Size Button. This apparently expands a case mouth in one pass through die and press - in the sizes offered.
1. How efficiently does this device work - that is, what is the [estimated??] case loss from split necks? Any recommendations or precautions to reduce this case loss?
2. I anticipate other die manufacturers offer devices whose purpose is similar to the Redding. Those with first-hand knowledge with expanding case mouths, what devices or procedures are among the most efficient? Any particular things to monitor or do when doing this type of job?
