RandyBaker Posted August 15, 2019 Share Posted August 15, 2019 The case on the left was with a Dillion die and Lee on the right. Is one better than the other? Link to comment Share on other sites More sharing options...
4n2t0 Posted August 15, 2019 Share Posted August 15, 2019 (edited) It looks like the Lee sized further down the case while the Dillon might have done a better job of undersizing (without measuring it's hard to tell). Both should work just fine. I like/use Dillon exclusively and have never had any issues. Edited August 15, 2019 by 4n2t0 Link to comment Share on other sites More sharing options...
Sarge Posted August 15, 2019 Share Posted August 15, 2019 My Dillon die allowed way too much set back so I went to EGW Udie for 9mm. Link to comment Share on other sites More sharing options...

Then when I got into PCC the LEE U die no longer worked due to the tighter chamber am about to try a EGW undersized die. So the answer is it will work or it won't. The 9mm is a tapered case and the die needs to go all the way down on many barrels not just most of the way. Link to comment Share on other sites More sharing options...

Just recently bought a PCC and had a couple get stuck while trying to eject a live round. This was with the Dillion die. Just went to lee so we will see if that changes things Link to comment Share on other sites More sharing options...
echotango Posted August 16, 2019 Share Posted August 16, 2019 Don't waste your time with a Dillon die. Get a u die. Link to comment Share on other sites More sharing options...

hamiltonian Posted August 16, 2019 Share Posted August 16, 2019 An undersized die for 9mm is the only way to go in my opinion. I got a Lee undersize 9mm die and now I do not have to worry about overall length changing. It provides more friction between the case and bullet, and works both ways: for 9mm major it keeps the bullets from creeping out of the case and also relieves any setback issues from feeding, etc. I have not experienced any negatives so far after A LOT of loaded rounds. My PCC works fine with reloads but it has a JP barrel which has a generous freebore to facilitate a range of overall lengths. Link to comment Share on other sites More sharing options...

If you're using softer coated lead bullets, yes; excessive neck tension can size the bullet down. Undersized bullets are bad for accuracy. With more common commercial hard cast or jacketed you won't experience that issue. Link to comment Share on other sites More sharing options...
Pc70 Posted August 16, 2019 Share Posted August 16, 2019 Lee makes the dies for EGW (that is direct from the EGW website). I bought a Lee undersize die for 40 and it cleared up some going into battery issues I was having on my 1911. I see more Lee undersized dies in my future. YMMV Link to comment Share on other sites More sharing options...
stick Posted August 16, 2019 Share Posted August 16, 2019 I've always run Lee sizing dies in my XL650. Especially for 9mm where I almost exclusively use mixed range brass. the U die is the way to go. Link to comment Share on other sites More sharing options...
noylj Posted August 16, 2019 Share Posted August 16, 2019 (edited) Lee and Hornady size down the furthest of common sizing dies, and Hornady and Redding size easier than other common sizing dies. I run mostly Lee on my 1050s, with some Hornady New Dimension. If dies don't chamber after sizing, Bulge Busting takes care of the problem.

Again, I've never had any issues whatsoever using Dillon dies. Maybe I'm just lucky but my rejection rate is less than 1%.
