Another thing to push you towards CH4D is that RCBS is no longer making Customs Dies. They will make special order dies to specification, but if you have to have special dimensions, they won't help.

If you need special dies just to fit your rifle CH4D is the place to go. www.CH4D.COM The best thing to do is first call Dave Davison and talk with him to get your specs down straight. He will then have you send some fired cases for measuring. Your dies may not come marked by a high dollar roll stamp machine, but the quality and tolerances of the working portion of the dies far exceeds RCBS. The only other Die company that I have seen come close is Redding
