I've had 2 squibs loading .38 Special on my Pro 1000. I try to visually check each round on the third station, for an appropriate amount of powder. It's much more difficult to do for .38 than for other cartridges that I load for, because of the height of the cartridge and the bare wisp of powder required.
I've gone back to loading .38 on a single stage press.
This is why I have gone back to loading everything on a single stage plus more accuracy. I gave both of my Pro 1000s to my nephew (actually one was his anyway). I can load all I need on a single stage. There seemed to be too much going on with the 1000 to suit me.
