I have loaded thousands and thousands of several different calibers of ammunition on my Dillon 550B. Recently, the case retaining spring (looks like a paper clip that has been reformed) became "tired" (after thirty years or so of use). I called Dillon, and like always the item is in the mail almost before I hang up the phone (absolutely GREAT service from Dillon).
I easily installed the spring, but had some difficulty in getting a satisfactory adjustment (I was loading .32's at the time). Then when I changed calibers to .45 ACP's, still more time for adjustment. What's going on here? I NEVER had that sort of trouble before, etc (to myself). Then, when I tried to set it up for .44's (special and mag) things just didn't want to work. When the case retention spring was correct for holdng the case in position, it interfered with moving the case to the next station. No amount of adjustment would help.
I didn't call Dillon, as this would have been difficult to explain over the phone and I am stubborn enough to try to fix it myself.
So, I quit "fiddling" with it and began to analyze the problem. I should have done that right from the first. It appeared to me that the right angle "leg" at the end of the spring was too long. It's only purpose is to form a "no stick" end on the spring to allow the cartridge case to smoothly move to the next station. Being too long, when I tried to move the case, the "too long leg" jammed against the tool frame.
So, I got out the Dremel and shortened the leg probably 1/16" to maybe 3/32". It now works like a charm.
If any of you are having problems similar to this, this is the fix. If you are not, you have just wasted time reading this.
It was frustrating while it was happening so I thought than maybe someone else might benefit from reading this.
