Thread: A then c and b??

You still need to check your brass length no matter what dies are used as the brass flows during firing. Some cartridges are worse than others. Some have virtually no flow eg Ackleys. After you have been loading for your particular cartridge for a while you develop a feel for how often you need to check case length. It is not something I get anal about anymore, more important to make sure they are all the same length.
