I bought a new set of Redding dies for my Ruger 280AI. After making measurements from a couple spent cases from my chamber, I had a good idea of how to dial in my FL due to give me the right amount of shoulder bump. I've got just one problem, though… my die isn't giving me enough bump! I have it screwed all the way down to kiss the shell holder, but still not enough. So I tried calling Redding today, but as of Friday, they're closed for two weeks. So have any of you folks heard about this before? I know the 280AI was a wildcat for years, but I would think after it became an official SAAMI cartridge, Redding would have built their FL die to spec. On the other hand, do you think my chamber is too small? Any advice is appreciated. I must be overlooking something.
