Tried to catch him at home this morning, but he was working an event somewhere. We have enough components for shotshells and loads for next month. He told his wife he got the barrel internal measured this week, but she didn't know what he found out. If I get anything in the way of data, can pass on to you if you think might have some relevance to your project.
