[QUOTE="243winxb, post: 1560026, member: 97793"] Brass Life - Running at 65,000 PSI in some factory loadings will stress brass. The factory gets away with it because its only 1 firing. When we reload, trying to match [B]or exceed[/B] factory velocities over a chronograph, the pressure may be the same or higher. At these pressures, brass life may be limited to 2 or 3 reloadings. Primer pockets may loosen, enlarge a small amount each firing. If pockets become loose sooner then 5 firings, the powder charge needs to be reduced. Accuracy should be found below the maximum loading data for longer case life. If you really need more or maximum velocity, trade up to a larger cartridge. There are many in the same bullet type diameter available today. This is general information, not directed at anyone. [/QUOTE]
