"im having problems with headspace on my bolt action rifles. Im looking for suggestions on a new die ..."
Dies are dies; they all work fine or they wouldn't be on the market for long.
Without a clue what "problems with headspace" you're having we can't help but it's highly unlikely getting a "new die" will make any difference.
We can't properly adjust any dies by rote, it's done for effect - if you need a different effect, adjust each die until it does what you want it to do.
