Primer Pocket

[divingin]

Watch your pressure with Peterson on the first loading. Not sure about their .30-06, but their 6BR brass is substantially heavier then Lapua 6BR.

IMO, you don't really need to prep the flash holes on either Lapua or Peterson. I would suggest a light inside/outside chamfer of the case mouths.

Lapua tends to be a little tight in the neck straight out of the box, as well.


Edit: I noticed I said flash holes; while my opinion remains accurate saying that, I actually meant to say primer pocket. "No need to prep pockets on Lapua or Peterson brass". Sorry about that.

I just use a flathead screwdriver that fits the pocket size exactly.

Yep!

Flash holes need to be handled with care because the opening affects how ignition occurs. May not cause problems with the fact of ignition per se, but it could affect repeatability and therefore overall accuracy. Stated differently, it may fire ... probably no problem at all. But if you want the hole to be precisely at the same spot each time messing with the size of the hole may not be a good idea.
