You know..back when I loaded 410s in large batches..I would take a hundred or so to work and deprime and resize...I mostly loaded Remingtons and the steel bases really needed resizing. I would do that from November to early March. The reason for the Remingtons is they would hold actual 1/2 ounce or slightly more. You are right..I'll try to do 50 or so tomorrow.. I wasted all day today at an auction. Only bought one rifle and some reloading items. I let a 629 get away for 475. Nice gun....but Stainless with full lug.
