EDITOR: The Hydro-forming saves the major step which is the most difficult one. Yes, the poster is correct that the shoulders will sharpen after first firing with powder. But generally speaking, the brass is quite usable after fire-forming. There is no reason NOT to shoot the hydro-formed cases in a match (unless perhaps you are at the Nationals). We’ve shot hydro-formed cases and achieved 3-shot accuracy in high ones, and won a local 600-yard match with the brass. Yes it looked better after the first live firing, but it was very accurate after hydro-forming alone.
