[QUOTE="Eagle Six, post: 668908, member: 49457"] Thanks folks for all the replies and valued information. Considering a typical caliber such as a 308 or 06, please take this statement and change what you think is incorrect..... "The sequence of case expansion would be the neck, shoulder, body, head/base." Would it be accurate to say the edge/radius* between the neck and shoulder was the first part of the case to feel the chamber pressure, then out along the neck, as it also progresses out along the shoulder, then the edge/radius* between the shoulder and the body, down the body and to the head/base? Or, would the very first part of the case to pressurize against the chamber start at the neck mouth and proceed back? * I've searched and have failed to find the proper nomenclature, if anyone has a diagram or definition and proper reference name, I would appreciate it. Best Regards.....Eagle Six [/QUOTE]
