[QUOTE="Brent, post: 21265, member: 99"] I use the Forester and if the mandrel is not tight it will cut thinner one side depending on which side the case mouth isn't touching when you tighten the collet down on the case. When I got the thing the .308 mandrel was so tight I had to chuck it in drill and polish .001" off to get the case over it without tremendous effort. Woops just a little too loose though. The side that was pressed away from the mandrel would always be cut, even if it was the thin side, all the while leaving the opposite thick side untouched. The collet was holding it off. Now I have to remove the expander mandrel from the die before sizing to keep it tight on the turner mandrel. It works OK now I guess. It all depends on my initial neck thickness though. I can see how reaming first then using a cutter that allows the case to float on the mandrel would produce more uniform thickness than a converted trimmer. [/QUOTE]
