Re: Lapua Brass
I debur the flash holes on all my Lapua brass from 308 - 338 Lapua. You WILL find burrs, contrary to popular belief, Lapua brass is punched just like remington, winchester etc. The only brass I have found that does not need deburring is Norma.
I use a K&M Flash Hole deburring tool and it works exceptionally well.
Learn from others mistakes, you won't live long enough to make them all yourself
