You can lead a horse to water, but ........
If you have an 80% count that have low spots, you must have gotten a bad run of brass, which occasionally happens even with Lapua. I've never seen that high a count of uneven thickness brass from Lapua in one batch and that's for six different calibers I use Lapua for. But I guess it happens. My point is simply that's not the norm of what I expect from Lapua and haven't experienced that quantity being off.
