I am just getting into reloading and had a question about buying my first die set. I am trying to decide between the RCBS 3-die set (20904) and the Redding 3-die set (80209) for my Marlin 45-70. I have read that both seem to be really good brands, but most people seem to give the edge to Redding over RCBS when comparing the two. If it matters, I just purchased a RCBS Rock Crusher kit, but I know either will fit it. First, I would like to know what is really the big difference between the two brands and what makes one better that the other. Second, I would like to know if the price difference between the RCBS and the Redding is worth it. I can get the RCBS die set for $40 total while the Redding set will be about $75 total. I realize that the 45-70 isn't exactly a sniper caliber but I would like the ammo that I turn out to be as accurate as possible. Besides, I am in the process of building an accuracy AR-15 and whatever brand I go with on this caliber will probably be the same that I go with when it comes time to start loading .223 rounds.
