I use the Lee push through sizers but am finding that a .360 cast bullet sized to .358 tends to get a thin "skirt" on the bottom edge from lead of the bottom driving band being pushed down.
How do people avoid this ridge of pushed down lead? Or how do people deal with cleaning the ridge up when it happens?
Myself I have been using a smaller 1/2 round tapered file edge like a deburring knife, to scrape the thin skirt off or at least out flat. I then follow with about six twists of a NOE base outside edge chamfer tool. that generally removes the lead skirt but is a fair amount of extra handling. And extra time invested in each bullet.
I tried running the current batch through Lee push through sizer base first. Was a flat nose profile so seemed like it was worth a try. Left an uneven skirt around the WC top band, where I can't remove it by trimming or with a chamfer tool. I think that is not a better solution.
