Resized case length vs fired length

[Hoot]

Here's a weird twist. I've only reloaded my first set of brass once, but after their initial firing, the cases did not grow one bit. I expected to need to trim them, but I didn't. Some actually shrunk a mil or two. Figure that one out... That was Hornady brass and Hornady New Dimension die which I'm not totally thrilled about the quality of. I've honed and polished it a little closer to my chamber now. Out of the box, it resized my .299 fired necks back to .285. The virgin brass came out of the box at .289, so I honed the die to resize the .299 to .289. Still a lot of brass working,but better than .285.
