New SAUM brass is .008" undersized on case head dimension.

[MagnumManiac]

I find nearly every batch of brass I have ever bought were at least .005” undersized at the case head and at the .200” datum.
I just think the brass firms want that extra wiggle room for their own peace of mind.
It hurts nothing on the initial firing.

Cheers.

is it that big of a deal? Just needs a reamer spec tweak? Kinda like norma 284 brass a tad different than Lapua 6.5x284 case
