I relocated some holes in my 452 sizer die and now the sized and lubed bullets have little lines in them.
Faint and just a few but there nonetheless.
I know what they are from - left over shot from a formerly plugged hole that is now open.
I took a 50 cal bronze brush and ran it through the die 100 times. It improved but did NOT get rid of the lines.
Is there something i can do OTHER THAN running the brush through there another 200 times and maybe or maybe not correcting the problem? I am just looking for a short cut that won't damage the sizer die.
I am thinking of a fine wet sandpaper around a dowel but I don't want to scratch the die.
Your thoughts?
