[QUOTE="bigedp51, post: 1456699, member: 28965"] With new unfired cases and with a full length resized cases the case body does not touch the chamber walls. And the only part of the case that touches the chamber is the case shoulder. This is where the expression "The cartridge should fit the chamber like a rat turd in a violin case". Bottom line, if a reloaded case does not have the same accuracy as a brand new case then there is a very good chance the case warped on the first firing. And this is caused by unequal case wall thickness and the case expanding more on the thin side of the case. [/QUOTE]
