Can someone help me understand something.
I’m reloading for a Ruger Ranch 6.5 Grendel. 2x or 3x shot brass comes out ~1.212 using the Hornady headspace guage. Running the brass through a Lee full length sizing die (1/4 past contact), it comes out to ~1.215/6. I know this rifle starts getting a tight bolt closure at ~1.218.
My question is, is the brass simply not fully formed to my rifle’s chamber? And the full length sizing die is actually stretching it some during the sizing process. Just wanting to wrap my head around it, so I can do what’s best and extend the life of my brass the best I can.
