Deburred flash hole

[shaunharkin]

would you deburred inside of the flash hole on 6mmbr lapua brass please

Most every one does, and it sure can't hurt to remove the little slivers that sometimes remain in the holes.... Use the smallest cutter you can buy that is speced for the 6BR Lapua flash hole....

Whose tool do you use that doesn't enlarge the flash hole diameter? All that I've tried enlarge the flash hole over the original 1.5mm,.059) dimension.
