Re: Resize .308 Lapua brass, or buy 7mm-08
Both approaches work just fine, necking down IF you either don't need to thin the necks or you can turn them down.
I see it as a money vs. time vs. both decision.
Necking Lapua--I strongly recommend annealing them the right way right after necking down (I did some 6.5 Creedmoor and the necks were HARD).
If the price is the same, I'd just buy the 7-08 stuff.
If Lapua is even a few dollars cheaper, I'd neck down...IF I have the time.
If I were totally anal and didn't care about money OR time, I'd buy Lapua and neck it down and turn the case necks and sort them by weight afterwards and mark the weight lots on the head with a punch (dots).
