Don't discount the Lee Collet die out of hand. Here is a short video I made.
OK, its not up to Redding Competition Bushing die standards, but at least any neck wall variation is pushed to the outside - good for hunting loads which you cant be bothered to neck turn
Likewise, they are great to use before neckturning - with the variation on the outside, you can get very consistent neck wall thickness.
I honestly believe these Lee Collets are better than any die with a button. That said, you do need a press with a positive handle stop. Without this the neck tension does seem to vary.
Kev.
