Please forgive my ignorance...It has been 5 years since I reloaded a 470 NE. I bought Norma brass from Raven Rock and they are great...the problem is when I went on Midway to order the RCBS dies. I thought all the 470 NE were 3 inches like my 500 NE? However when I got my RCBS 470 NE die it says 3 1/4 inch. I can't reload yet but will that be a problem? RCBS does not list any 470 NE die except in 3 1/4 inches.
