Hi, All-
I have been reloading for several years on a Hornady L-N-L AP, and just added a new 650 to my Routine. I got the press set up without difficulty, but ran into issues with one die. for starters, I guess I should mention that I purchased the press set up for .45 ACP. Instead of ordering the Dillon dies, I opted to start with a new set of Hornady Custom Grade dies that I already have. As I was setting up the new dies, I quickly discovered that my brass was hitting near the outside edge of my resizing/depriming die in station #1.
I worked with the press for more than two hours attempting to figure out, including confirming that I am using the proper shellplate, tightening/loosening the shell plate to see if there is a "sweetspot," checking the indexing to verify that is is indexing properly, verifying that the toolhead is seated as it should be, and working with the actual die to make sure that the trouble wasn't originating there. I even went to Gander Mountain and purchased a new RCBS die set just to see if it would work with better precision. I had the same problem with the RCBS die.
Finally, I called the service department at Dillon and was told that I would probably need to use a Dillon die as they operate the best on their progressive presses. I don't question at all that dillon makes quality dies; however, one of the two primary reasons for going with the 650 is that it uses the standard universal threads which can accommodate many of the dies I already own. I guess I was still unconvinced after our conversation, so I kept trying to ascertain the problem. What I noticed next leads me to wonder if this could be the culprit. I took all the dies out of the press and watched from a top view as the brass cycled in the press. What I noticed is that in stations 1 & 3, the brass does not come up into the center of the die holes. In fact they seem to be off-center significantly. Oddly, though, 4 & 5 are perfect, and #2 isn't off by much.
I also noticed that when I watched the brass on the upstroke, the bullets enter the dies at a slight angle, rather than directly parallel to the walls of the dies. I then found that I can "force" the brass into the resizing die, but again, only by manifpulating each piece by hand, causing it to enter at a fairly extreme angle. It doesn't seem to impact the operation of the press or the dies, but I am wondering if that could be the cause of my problem.
Ultimately, I am pleased with the solid feel of the press, but am wondering if I am going to have to purchase all new resizing dies from Dillon, or if this is a remediable issue.
Thanks!
Chris
