[QUOTE="bigedp51, post: 1306922, member: 28965"] CatShooter The blade micrometer doesn't need to have a heart attack but the reloader needs to know he has exceeded the elastic limits of the brass. Brass flow into the ejector or base expansion means the brass does not like this high of chamber pressure. Inflating my cars tires to a higher pressure gives me better gas mileage, "BUT" it wears the center of the tires tread and decreases tire life. Meaning why over stress the brass to the point of brass flow and exceeding its elastic limits and shorten case life. The photo below came from Accurate Shooter reloading forum and was about "brass hardness" when you posted your hardness tests, The person who posted this photo said he increased the load until he got brass flow into the ejector and then backed 1 or 2 grains. Meaning he tested the brass elastic limits and then kept below this pressure point to make the brass last longer.
