Unsupported Chambers

unsupported chambers

A chamber provides full cartridge case support only if the case is supported down to the level of the INSIDE BOTTOM of the case, which typically is about 0.05-inch (one-twentieth inch) above the start of the case extraction groove outside. Thus any chamber that provides case support all the way down to the extraction groove… read more

Kink During Last Crimp If you are finding that your… read more

Dillon vs Lee vs Hornady

Dillon vs Lee vs Hornady What’s the Deal? Why bother? Some people like blue, others shades of red. Who cares?
