I can promise you that he either is GREATLY exaggerating or he learned how to make brass last after he got the Lapua. There is nothing magic about the stuff. The reason that people like it is that it is consistent and all the queepy prep work is already done.

I started with 300 pieces of Win .243 brass and did all the prep work (size, trim, chamfer, deburr, debur the flash hole). After that I weight sorted them by 0.5gn groups of 50. The total spread of the group was around 4gns. The two median groups were within 0.2gn There were only a few cases outside of 1gn and they got pulled out as sighters. All in all I paid about the same for those 300 cases as 100 Lapua would have cost.

I realize that there isn't a lot of good .260 brass out there. I guess it just comes down to how much your time is worth. Buy Lapua for 2x the price or form .260 brass from Win .308 (or .243 if you have a tight necked chamber) and have 2x the number of cases for the additional cost of your time.
