Just got off the phone from Redding . Mentioned I've been sizing 6.5x284 to 6 x284 in one shot by running the case in their Type C series FL sizeing die. They said "I should be sizing it first in their standard seating die and then next step in the FL die I have". So now I'm wondering if I have the Do-nut effect inside the necks of my brass ? Can I see that from just looking in? Our do I need to run a paper clip are some thing to feel for it ? Hope I haven't ruined some expensive Lapua brass ?
