My Lee universal decapper keeps popping up even though I've got it cranked down (yes the pin, not just the die!). Didn't notice it for a run of 20 rounds! Gave my bullet puller a workout! I didn't notice anything wrong, just seems to do it at random. Surprised my priming system didn't get messed up, but seems fine. Probably have a few live primers in the bottom of the press! Any tricks to this thing? Or just REALLY crank it down?
Decapper Pops up?

Really crank it down. In stages.
I recommend taking the die out of the press and putting a good sized wrench on the flats for the die, and using a 7/16" (I think) on the decapping rod nut. If anything goes wrong you won't damage the press.
Tighten the thing and reinstall. If the tension is not enough, crank it a little more. When the thing stops misbehaving, no more tightening is needed.

Half inch, or 13mm for the nut. Yeah, you have to crank it tight. I have noticed that sometimes the shaft is too long and it will pop up a slight amount because it bottoms out on the flash-holes. The decapping pin is long enough to decap despite this, so if it only pops up a bit, don't worry. Don't feel bad, on a progressive it's easy to miss. I did the same thing a few weeks ago. The decapper pushed up on a berdan case that was mixed in and the priming arm jumped the slider pin when it got to the second stage. I found out when I made a routine check of a finished round as it came off the FCD. Only had to pull six.
Yes all regular boxer, 45 ACP pistol ammo. Nothing exotic.
I took out the die, carefully re-set it, locked the ring down, took it back out, placed some brass in the die to where I could see the die hitting it with turret full up, placed the pin in without bottoming on the brass, AND CRANKED THE CRAP OUT OF IT with two wrenches!! I even stood on the wrenches a couple of times to get MORE POWER, Tim Turner style. If it backs out now I may have to give up (or use my breaker bar on it)!

make sure you degrease the rod and inside of the nut where they contact so it gets a better grip mine came out the first time also. Cleaned it wrenched it down and had no more problems.

I've ran into the flash holes being off centered from several brands. Just something else to look at....
