I'd just go to Redding if I were you. Buying used dies is usually OK but there is always that exception. You say 3 die set so I assume you want a neck sizer a seater and a body bump die and Redding has a nice set in that combination. I have used and loaded that round for a number of years and it is a very nice and underrated caliber.... 30-338
You can pick up a 2 die set from RCBS very reasobably and adjust the die so that it is bumping the neck slightly.. good luck 30-338
