When I first switched to the Redding Competition Seating Die in a standard press, all my ammo runout was within 0.001" except where the neck wall uniformity was worse than that. This was loading .30-06 shooting 168 grain MatchKings. I've subsequently moved to the Forster Co-ax press, but am still using that die and getting the same result. What I don't know is how different ogive shapes will do in the die. The Sierra 168's and 175's work great in it, though.
John Feamster, writing in the Precision Shooting Reloading Guide loaded some .308 ammo with an RCBS standard seater, and RCBS match seater (the kind with the side window), and Wilson dies in the arbor press. The standard seater did best for him and the Wilson did worst. I have no idea why that's even possible, but I'm just passing it along. Unexpected things can happen.
