DimitriS--You'll want a neck-sizer die also--after the cases are fire-formed in yr bolt-action, you neck-size them, not FL size them, and they fit the chamber of the rifle better that way. Translates into greater accuracy.
I like the Lee Collet neck-sizing dies. Have 'em in several cartridges and they work nicely for me.
Were I you, I'd go with Unclenick's reccommendation on the Redding Comp Seater Die. Keeping the bullet runout as small as possible, again, translates to accuracy. (Runout=deviation from exactly straight in relation to the axis of the cartridge, and eventually, the axis of your bore.)
