I PC'ed several of the boolits that I cast in the last few days, let them set overnight and ran them through the appropriate Lee sizer. 9mm were dropping from the mold at almost .360". After coating I ran a few through a .356 Lee sizer and they measured just over .355. On at least one a good portion of PC was scraped off of the bands and base on one side of the boolit.
I have seen others post that they size and then PC. Does this not build up lead inside the sizer? This would prevent dragging the coating off if it did not lead up the sizer. I also have a .358 sizer that sizes a little over .357 but that may be too big for 9mm. I have not slugged the bore of either 9mm yet. Any ideas/ opinions/ suggestions? Thanks.
