    Loading for about a year now, and rounds are shooting well and I'm staying competitive in matches with my loads, but not really sure about this. I'm measuring a fired case with the Hornady headspace gauge or shoulder gauge and it's typically approximately 1.625, now I was taught to just try to bump back .001 to .002 in resizing. So I had everything set up and was getting cases coming out at 1.624 to 1.623 and thought Ok swell right on target. After seating I gave rounds another check just for kicks and then found the measurement to be 1.620 to 1.622, What the @!$& ? Am I doing something wrong or missing something ? Im turning out the overall length I want (measured to Ogive) and all, and rounds are shooting fine but am just perplexed as to the change.

    What caliber?

    What is your bullet grip (ID of neck after sizing)?

    How many firings on the case?

    Are they annealed?

    What kind of seating die?
