Which powder cop will work on this press?
Thinking Dillon, any problems?

Not sure it really matters. More of a personal preference thing.

I use the Hornady powder cop, for what it’s worth.

I've been satisfied with the RCBS Lockout die...I use it on station 3 on my old Dillon 450 since I seat and crimp at the same time on station 4...it stops an uncharged/overcharged case, plus it's somewhat less expensive than the Dillon powder check die...

Any powder cop will work, but I would ONLY use the RCBS lock-out die or the Dillon. The lock-out die STOPS the press if it detects too much or too little powder. The Dillon buzzes at you, but you had better check it occasionally to ensure the battery works.
IF you can't look in the case—it's right there under you nose at station 4 before you put a bullet on it—what makes you think you'll look at a powder cop that just goes up and down and doesn't stop you in any way?

To use the Dillon you will have to drill a hole for the push rod.

When you receive it and set it up, here are a couple of links to YouTube videos that help with the initial adjustments...as well as showing the dies operation...

Thanks Bisley. I did a lot of searching before deciding which die to use. I found the video of setting up the RCBS die. I use Trail Boss in one of my loads which does not meter very well. Just wondering how the RCBS die is going to work with Trail Boss.

Received my RSBS Lockout Die today. Had it setup in just a few minutes. Loading 4.5 grains of Trail Boss it will lockup at 4.0 grains and 5.0 grains. Will check other weights later.

I keep my Lock-Out dies loose. Mine can detect the change in case capacity. I have learned that with my dies, if I turn them less that 1/12 of a turn to release the die, the charge is correct +/- 0.1gn so far after more than 5 years. I still always check the charge weight on any case that locks it up.

noylj sorry but I do not understand you post.

Really simple.
I found that my dies are sensitive enough to detect changes in height just from case differences. So, I DON'T tighten the die body with the lock ring. When I get a lock up, I lower the ram a little and turn the die body one way or the other so I can cycle the press. I then remove that case and check the powder weight and, if correct, return it to the shell plate. So far, any time I have only needed to turn the die body about 1/12 of a turn, the charge weight has been exactly right.
I don't believe in EVER short stroking, so I adjust the die to I can completer the stroke and then check that case.
