Perfect full length size die

[mr.big]

For my 6 PPC chamber. Harrells Precision makes 8 different fl size dies for the 6 ppc. You send them some fired unsized brass from your rifle and they send you the correct die.
Bolt closes like it isn't loaded without overworking your brass and it's very straight
Brass measured before and after sizing

That is indeed precision.

I will be doing the same measurements on every caliber I load, just to see what I got.

No bets on anything under 1/10th inch.
