Sounds like a flake got up into somewhere it shouldn't have been. Did disassembling / cleaning help?My first RCBS lock out die, the plunger rod would occasionally “stick” in the up position

That's interesting. I would have thought a more dense powder would have allowed for more of an over/under charge than a bulkier powder. On the low end mine pretty much needs a "no charge" to lock out. There are probably a few other variables, including aspect ratio of the case. Tall thin cases would have more of a delta in charge height between max and min than shorter stubbier ones, it seems to me.I did the same test using ball powder (HS-6) and found that at 7 grains and 13 grains, the lockout die would activate at around 15% over and under charge. Use them on all my progressive presses, use the Hornady powder cop on turrets.
It's been awhile, but I think I used a 44 mag case for both measurements rather than try specific cases for the individual charges. I didn't think the case size would matter since I was just measuring charge.That's interesting.

What was the caliber you were reloading? I was reloading .45acp, so it's a pretty short, fat case.
Either way that's pretty good. Even if you were at maximum charge I would be surprised if a single round at 15% over would blow up your gun. And I would expect at 15% under the bullet would still make it out of the barrel. Nice to have that level of comfort.

Disassembled and cleaned twice. The mechanism is very simple so it was a mystery. There were no burrs, sharp edges, everything looked fine and RCBS couldn’t find anything either, or at least that they told me.Sounds like a flake got up into somewhere it shouldn't have been.

As do I, however on a progressive one can zone out for a few and having a device back you up isn’t a bad thing. CBLFs are capable of mistakes.I don't trust powder charges to some little gizmo ... I trust the two eyes God gave me .
