SAAMI drawings. I looked up .243 Winchester to see what the maximum cartridge dimensions are and confirmed what I thought was wrong with Fiocchi .243 brass. The necks on some of my loaded ammunition is measuring .2765 to .2770 and one was .2780 no way they would chamber. Maximum cartridge diameter is .276 and minimum neck diameter in the chamber is .277.
When reloading it would be a good idea to use these drawings as a reference because all components are different from brand to brand brass is probably the most inconsistent.
