[QUOTE="nksmfamjp, post: 1970911, member: 1951"] Well, quick update.... I’m loading 300 WSM, Win brass, neck turned to 0.013 thickness. Fired neck runout is about 0.0017”. From my Forester FL die with expander this brass will FL size to CBTD fired -0.0015 with a neck runout averaging 0.0013.” I ran some through my Redding type S die with floating carbide expander. It gave me 0.003” runout. I measured the decapping rod and it had a little over 0.001” runout and had more runout in the decapping pin. I ordered a new one. Next, I want to try multiple sizing steps with the Redding die and with/without expander in the die. Also will try expanding on my k&m mandrel. Last, the very tips of my case necks curl in to a smaller diameter. Anybody know why? Not hitting end of the chamber? I’ll have to look in there with my borescope... [/QUOTE]
