Matt I have been using it since it became available but have only fired cases a maximum of three times. Primer pockets are very tight when new and haven't loosened yet but my loads are pretty mild and I use moly coated projectiles so pressures are pretty low.Velocities up to 2830 fps with 180 vlds haven't loosened any. The brass is a bit heavier than Lapua and I find I use about one grain less of 2209 for the same velocity. Some of the necks varied a bit in the batch I have so I I have given them a light skim to even them up.
Seems like tough brass that will last a long time.
Steve.
