I tell ya, when it comes to presses, only thing that matters is, is the thing square. I also have RCBS and Lee, but don't use the lee anymore. But, I just got some Redding FL dies for my 7mmSTW, and I can't say I am inpressed at all. The expander ball is not straight with the die and causes slight runout issues. Now RCBS does the same, but the difference is there is a work around for RCBS. You can decap with a universal decapper, then raise your expander ball all the way up to where when it starts coming out, the neck gets expanded instantly. This method works great and is possible cause the expander/decapper is threaded all the way where the redding is not. So I ordered a set of RCBS. I called redding, and they said, "yes, there will be some wobble, all we can do is have you send them back and we can try to match up the expander/Decapper post with the die body not to wobble".

One thing, the redding comp dies are the finest I ever seen. But cost almost 3 or so times more than the regular dies. They may not be neccassary, but are fine dies to say the least. They better for more than 100 dollars.
