I agree with BigCountry about the Redding dies. However I have started using the Forester seating die-without the caliper. It is available with the caliper. The caliper makes the die a lot easier to use, but it is not necessary if you pay close attention(and write down) everything you do. I have also started using their sizing die, and I like them alot. IMO the seater is every bit as good as the Redding(they work exactly the same, with the brass aligning encasement). They are priced less than the Redding. As B.C. said-you need to get a good seater.
