When your piggyback overcharged...were you using a lockout or powder checker die?
Good question. That was probably 1998 ish. I am uncertain as it was too long ago to recall clearly. I have a powder checker die, but I can not say for certain I had it on the turret of the Piggyback. I would think I did, but I can't guarantee that. I was using a Uniflow powder drop with micrometer adjustment accessory (an upgrade to the Uniflow back then), so it is very odd that it happened. I ran thousands of cartridges through that Piggyback, Captain, mostly 9mil and 380 with some 38 spl/357 and 44 spl/44 mag, and the only one that overcharged was a lone 357 mag.
The only thing I can think of is that I somehow jerked or paused and reset the reloading lever in a funky manner one time and that somehow gave me more powder than the Uniflow micrometer was set for. LIke I somehow went half way, the powder dropped partially, I stopped and put the lever back to rest and started again dropping even more powder. I'm totally guessing here, and it seems ridiculous that I would have done this, but who knows. Regardless, with uniform press rhythm, that should not have happened. At least, to my thinking anyway.
