This case would be .008 "LONGER" in cartridge headspace after sizing and not shorter.
Bottom line how can a .008 longer case when chambered not be dented and the shorter cases are dented? I was thinking the cases were dented from over lubrication and by pushing the cases into the die .008 "less" the OP left more shoulder room for the lube.
A standard shell holder has a deck height of .125 and the +.008 shell holder would have a deck height of .133 which lowers the case in the shell holder. Meaning the case is pushed .008 "LESS" into the die making the cartridge headspace "LONGER". This Redding +.008 shell holder would be the same as placing a .008 feeler gauge on top of the shell holder and then screwing the die down until it contacts the feeler gauge.
As the saying goes, "I'm not sure I understand everything I don't know about this."
