Lapua flash holes are drilled not punched so there is no need to debur them.
Lapua brass is the best stuff going!! I plan my rifle builds around the availability of Lapua brass.
I run it through a full length die and load!!
I disagree. I looked in my new cases and could see burrs with the naked eye. Looked mush smoother after deburring with the appropriate tool.
Same as drilling through a piece of steel, drill bit always leaves rough burrs on the backside of whatever material you are drilling.
