Military brass

[Wes Sage]

In 308 and 30-06 it holds true quite a bit as the brass is thicker, and has less internal case volume.

In 223/5.56, it doesn't hold true as some military brass it thinner than their commercial counterpart.

Always best to work up loads and watch for pressure signs. Even a different gun may not shoot a proven load in another gun, due to chamber differences.

I am pretty new to reloading and someone told me I should reduce the powder charge by 10% with military brass over non military brass . Is this true? Thank you all.
