[QUOTE="Chad Erickson, post: 2582728, member: 122822"] There are several ways that a case can fail: neck split, case shoulder split, loose primer pocket, and head separation. The most fatal of these, at least to your hunting trip, is head separation. As all know who have experienced it, full head separation leaves your firearm inoperable until you can get the front of the case removed. If you are loading a high powered cartridge with the higher allowed pressures, I suggest the following safety technique: 1. Take a 16d nail to your anvil and with a hammer, flatten the pointed end until the first 3/4" is an 1/8" thick spear. 2. While beating with the hammer, bend the spear 90° so a sharp point is perpendicular to the main nail shaft. 3. Insert the bent point into the case all the way to the head. 4. With the case horizontal, slowly drag the point back and forth in the area where head separations happen. 5. Rotate the case and test in at least four locations. 6. If you feel the slighted grab or hesitation, head separation has began and the case should be discarded. This method will detect head separation several reloads before the actual event. [/QUOTE]
