I have read many posts on this forum and others telling people to use you FL body die with the guts removed and then use your collet die after, ok, I tried it, with the guts removed from your FL body die it compresses the neck, without the expander the neck stays sized down quite a bit. Ok so I did that, now on to the collet die, well lots of pressure to get it started, keep going let's get this neck sized, that's what I do and .003 runout on case neck, ok they say use a little lube inside neck, same thing, bad runout. This makes no sense, I'm basically using the mandrel on my collet die to expand the neck and it floats so with all that pressure it will move the neck one way or another, can anyone explain how this works, I have switched to a body die which works great cause the collet die ain't doing anything to the neck till it's actually forming on the collet but I see this posted everywhere, was I doing something wrong?
