DMC said:+1 on the above, I just fire formed 100 new cases, shot lights out. Fire formed during local 300 comp's, was going to buy one of those hydro dies, but in the end , i thought it wasn't worth it i my case. secret to fire forming for me was 205 primers ( soft ) normal 6mm BR load of varget, 107 SMK with 20 thou jam, and a completely dry chamber. consistant fire formed lengths on cases and very accurate - works for me !
