Let me know how that Nosler brass works out for you. I can just about guarantee you it will vary way more than +or- 0.5 grains.I am going to try some Nosler brass from Sinclair:
Nosler takes a few extra steps with their brass to make it a premium component for the handloader. The brass is first weigh-sorted to within + or - 0.5 grains, then the flash holes are deburred. Nosler completes the case prep with neck sizing and chamfering the inside and outside of the case mouth. All Nosler unprimed brass bears the Nosler headstamp. Sold in boxes of 50 unless stated otherwise.
They may be better than anything Lapua would come up with for the 6.5 Creedmoor.
