I have recently started using "blem" bullets due to their lesser cost and have been pleasantly surprised and satisfied with their accuracy! Just to be honest most of the ones I have bought could not be distinguished from "first" quality bullets and those that I have measured only had a discrepancy of.005-.008 with the tip.

With that said, the description most times with these "blems" goes some thing like this. "For majority of the bullets being offered, this blemish is a slight discoloration in the jacket or the bullets were run during press set-up"

I guess my question has to do with the "were run during press set-up"! What are the issues with "press set-up"??
