I recently recieved a large bag of nickel-plated once-fired LE brass. It quickly became apparent that a large number of the cases were distinctly off-round at the mouth. The kinked ones and severely deformed ones went straight to scrap, but that leaves a lot of somewhat ovoid-mouthed cases. They seem to form back to round when run through a sizer, with no nicks in the case rim. Is this too much deformation? What is an acceptable margin?
