This 243 Winchester AI project is my first with a wildcat requiring cartridges to be fire formed from another cartridge. In this case the 243 Winchester. Today was the first to begin the process.
Each shot produced what seems to be a perfect Ackley Improved cartridge. The only thing that seemed odd is the primers backed out of the pocket a bit. I don't know what this means. The fired cartridge was easy to extract from the chamber. There are no extractor marks on the base, nor is the primer flat or cratered. Any ideas what might be causing this, and is there reason for concern? My load is listed below.
* New Lapua 243 Win brass
* Federal 210 primers
* 47.0 grains H450 powder
* Hornady 90 grain ELD-X bullet
* COAL = 2.70
