Sizing brass, Am i missing something?

[Tactical30]

I have been reloading for about 4 months now and mostly reload for .223/5.56, .300 win mag, 45 ACP, 50AE. I had just started to reload for the 6.5 Grendel and had ordered new brass from Alexander Arms (100pcs). Nice brass, No dents or anything. Anyhow, I sized them out of the box just so I know all is good and what was odd to me is i measured them out of the box and then measured them after I full length sized them. It straighted the necks and everything out but there was absolutly no gain in length. Which is good i guess so i dont have to trim but I thought nomatter what when you FL sized the brass is going to grow at least a little. Every single other piece of brass i ever FL sized grew at least some. Whats the deal here?

Your size die didn't have to reduce the size of the virgin brass enough to cause growth.

Brass doesn't always grow in length. Smometimes the necks just get thicker.

Agree. At least most virgin brass should be very close to spec. For that reason, I only resize it if I want to "iron out" any dents in the mouth. With that, I only neck size it. Takes less time. You know, I 'd rather shoot than prep cases.
