Hi,
when ordering Lothar Walther barrel there is an option for chamber protrusion and i've asked them what it means and response was:
"the protrusion is the differents between the ending of the barrel and the end off the cartridge (gauge)
it can be from minus to plus. "
As far as i understand what good would that be other for final headspacing (have a bit of extra meat to grind off and fine tune headspace to clients liking). I can't imagine -protrusion and having some part of the case exposed be a good thing?
