.256 Win Mag Form And Trim Die

After using Form Die#2 This one will take your Inside case neck diameter from .292" down to .261" you don't have to re-lube the case if you just used form die#2. You can use a file to trim off the excess brass. Your case will measure 1.298" before filing and 1.285" after you file it. This is .004" longer than the trim to length. when you run the case through your full length sizing die it will be .010" too long. Rather than having to trim them twice I use a case trimmer as the last step after full length resizing. Hint: I wiped the lube from the shoulder and neck area on the case. If you get wrinkles on the shoulder it is from too much lube. Then I anneal the case and your ready to load!
