sizing help

From what I've read here I have been resizing incorrectly. My brass comes out of the rifle at 1.640, the bolt closes on a 1.638 case, the builder says its a 1.632 chamber, I've resizing to 1.630 per Zediker, is this why my last 1000 reloads suck?? I need to resize to only 1.638? thanks ahead of time!

I bet a buck you are measuring with a stoney point tool?

Sounds like 1638 (on your tool) is OK. This will bump the shoulder back 2 mils - is that what you are telling us??

2 mils isn't much - try 4 mils instead?
