The "U" die is .0001" undersized, so it sizes the case down smaller. There is also less bevel at the bottom of the die, so it sizes further down on the case, eliminating even more of the bulge.
I was hijacking. My Lee dies didn't seem to have enough thread length to work in the Dillon tool head. I'll ask somewhere else, save this guys thread.
I have to use RCBS or Lyman locking rings to use Lee dies on my 550,I get just enough thread to lock down.I was hijacking. My Lee dies didn't seem to have enough thread length to work in the Dillon tool head. I'll ask somewhere else, save this guys thread.
Looks to me like the cases weren't resized full length.
I've been thinking about this...
The UGW isnt a full pass through is it? Keep in mind, I deal more with .40 brass and use a G-Rx for resizing (which is a full pass through die). The reason I'm asking is that if its a pass through die, and the 9mm is tapered (at least I thought 9mm was tapered) how does it handle it? If its just machined to size further down, I guess it isnt an issue.
Just interested, like I said, been thinking...
... which in my case is dangerous.
