[QUOTE="tobnpr, post: 1942709, member: 68758"] Without going through your measurements, if a field gauge chambers easily, the barrel is a tomato stake. We all know that slightly excessive headspace can be dealt with simply with die adjustments. When you get to the point you're at you've got far too much case exposed, read- not just the thickened area of the case head beyond the breech, but now the thin case wall above it. Being unsupported by the chamber wall is a recipe for a casehead separation. This is basic stuff- field gauges were made for one purpose; to distinguish service rifles that were "marginally" safe. Fail no-go, but pass field= safe to fire- BUT remove from service as soon as practicable. Fail field gauge- remove from service. Fail a field gauge= unsafe to fire. Full stop. [/QUOTE]
