Well, I sent the slug to Matt Dardas from Dardas cast bullets. They offer a free service to measure 3 and 5 groove slugs. I assume that he used an anvil mic. to measure it. I certainly was surprised at the result. Regardless, I'm going to experiment with a no crimp load. I use Wolf's Lee 5 die set up which has a compression die and separate seating and crimp dies.
