Reloading my nephew's Tikka T3X in 300 win mag. Once fired cases measure 2.273" and chamber like butter. No tension at all, with a stripped bolt (no firing pin or ejector button). Ran one through the die while using a .010 Redding comp shellholder (least affecting) and the case actually grew to 2.275". It still chambered with no resistance. Is this normal for a chamber to be so "loose"? Anyone have similar experience with a Tikka having a chamber like this?
