[QUOTE="Canadian Bushman, post: 916217, member: 41122"] Thats gonna be dependant on a few variables like the thickness of the brass, the temper of that batch, the pressure of the current firing and the firings thereafter etc. your current cases strecthed. .006" so thats .003" per side, about the same as a human hair. Id say when you get to .005-.007" a side (.010-.015 per diameter) you are flirting with case failure. Again this is a rough estimate based on what ive seen and the moderate pressure of the 300 savage. A rifle i currently reload for streches about .002-.003 per side and i start seeing rings indicating web fatigue around 5-6 firings. When i recklessly fl sized i experienced a case head seperation at 6 firings. [/QUOTE]
