Thread: Cratered Primer

Greetings Again,
There is one thing that you can look out for which would indicate an over sized case. If you load and fire some of your full length sized cases with the same load and compare the outer edge of the primer you my find that the corner to the primer to the full length sized case is a little sharper than that to the neck sized one. It may even be riveted a little where the primer has a sharp edge at the corner like the brim of a hat. If there is a minor change and definitely no riveting your head space and full length sizing is not excessive.
These changes are often mistaken for high pressure by primer readers when they are just head space. I will try and do some photos with my new camera after I have finished my wood shed floor in a day or two.
