I have been reloading for awhile now but never tried this before. I just made my own COAL gauge by cutting the neck and drilling out the flash hole. I use a section of cleaning rod to push the bullet forward. For my 10fcp-hs I got these 5 results: 2.686, 2.685, 2.688, 2.686, 2.687. That is just touchings the lands. Sound right???
