I just spent
Started setting up the XL650, man this thing has a lot of moving parts etc. I won't lie it's a little intimidating. Should be running off a few test cases tonight hopefully.
Lots of good videos online, and Dillon has awesome tech support.
Thoughts (based on my own usage):
Set the tension on the shell plate carefully - and be sure to loosen/tighten the set screw that runs horizontally against that shell plate bolt.
Make sure you put the safety rod to the powder dispenser in correctly. It goes in from the left.
Check the nuts on your dies occasionally - if the die backs out slowly, all kinds of fun things happen depending upon which die it is.
Make sure that the powder dispenser drops down all the way over its die.
When you're loading, go slow and smooth, (as you get used to it go faster but stay smooth). Jolting it will spill powder.
You can FEEL that primer seating. If you don't, then stop and look at it.
De-capping a .380 will feel different than a 9mm; if it feels different - stop and look.
Do NOT force the down stroke, you'll quite possibly break the plastic ring underneath.
If you do break that ring - a piece of dental floss is helpful in putting the spring on on the new one.
Speaking of which - get the spare parts kit. If you break something, you can replace it - and Dillon will send you another one no charge. With the spare parts kit in hand, you're not waiting for the spare part to arrive.
If you don't already have one, get a gauge checker. I like ECW's.
UFO makes a really nice light for the press. I put a switched outlet into the housing of my casefeeder and plug the light in there.
The XL650 is my first press. It was a gift from my wife, chosen by her without any input by me - it was a surprise gift. I really like it - and now that I've been using it for a couple of years, I can start to compare it to others - it stacks up favorably.
