Re: Checking new Nosler brass- opinion #2
That is pretty inconsistent neck thickness'. Have you turned the cases to look foir runout?
I have a ball setup, like a commercial setup and a .001" dial indicator. I just finished running some of the heavier sorted batch and half have .002 or less neck OD runout, the other half had .003 to .006 runout. I will run these through the size die tomorrow and see if they true up.
A few of the fired Wby 150 partition brass I shot have .001-.002 runout, and a few are .004-.005 runout. The new ammo is .005 to .007 runout..... maybe why the gun didn't group as well as I had hoped. I would have expected the Wby ammo to have less runout than my measurments.
