I recently discussed the "blem" issue with the Nosler sales rep for the Northwest. "Blems" are the first 2,000 bullets that come off any new production run. They are considered blems because they are handled for measuring, weighing, etc. to make sure the dies are properly calibrated for the production run. It does not mean that they have any form of defect, not even cosmetic. Bullets that flunk weight, measurement, etc are destroyed. The "blems" are packaged in bags instead of boxes and sold exclusively through a shop in Oregon. If you carefully weigh and measure boxed non-blem Noslers, you will find all the same variations as with the blems.
