[QUOTE="Fitch, post: 414417, member: 19372"] That question, "Is the rifle properly head spaced?", is answered with Go/No-Go gages, not brass. Brass is about as dimensionally stable as soft cheese compared to precision ground Go/No-Go gages. That said, 0.005" from factory new brass to once fired brass is relatively common. How much it stretches on the second firing depends on how you size the brass, not the rifle chamber. If you size it to "just" bump the shoulders .002" or so, it will chamber and won't stretch nearly as much. If you neck size it it may be a trifle stiff to chamber but it won't stretch much, if at all. [/QUOTE]
