RE: Which Die?
There are a lot of options and a number of successful companies out there making reloading dies. The reason these companies are successful is because they are making good Dies.
For a full-length die I think I would be Happy with Redding, Hornady, RCBS & Forester.
As mentioned above the Forster Benchrest bullet-seating die, is top notch. Redding makes a similar competition-seating die, which is similar to the Forester and looks nicer. Of course Redding wants a little more for their nicer looking, quality seating die than the Forester. I think either will do a great job.
Would anyone be able to compare Hornady’ S seating die to the forester? I have never handled the Hornady dies B4, although I have heard good things about their dies.
