OK, could be rando due to a limited cross section, could be something.
I have been reloading on a Lee Pro 1000. about 6-10% of my finished rounds end up oversized at the base so that they AAAAALMOST go into battery, but not quite. and to get the gun to open requires some substantial pounding or pushing the edge of the slide on a solid object to open the action. So I bought a bulge buster, and that will size down all but the last 1-2% of those oversized rounds. So I just pitch those. These are all when I do all operations in one progression as designed.
So on a whim I tried running the setup with everything in place, just no primers, powder, or bullets; I removed no dies. Now I'm down to 1-2%needing ANY resizing. Even the handful that were close that would recover after the bulge buster werent required to be resized. I presume those 1 or 2 shells are statistically the same ones that I just couldnt correct with the buster and there was just not helping them no matter what.
And these are not suffering the Glock Bulge. They are just not sizing all the way to the base as far as I can tell.
I have a solution at the moment, but would prefer not to have to cycle a shell through the press twice. Any ideas what would cause this when using the press as designed vs a size only pass first?
