Thread: Playing with some Redding Competition Shell Holders

Here's a chart to help understand Redding Competition Shell Holders and what effect they have. This is my set measured using a Mitutoyo depth micrometer so reasonably accurate. I measured at three points on each shell holder. They were very consistent with the three points measuring extremely close. I had measured my set previously using a dial calliper but the measurements were not as repeatable and therefore suss.
