ok. I see 2 circumferential separations, clean-circumferential... one with powder could be over-loaded with a 120-gr bullet loaded tight or in the lands (AR comp has more variation in powder loads than most powders I use, and I use AR comp in the grr and 27.7 in one of my lots... is over), and 1 circumferential case separation in a wildcat with fatigued brass (20-25x loads) admittedly in unknown pressure/load arena for his charge...
Still don't see a generalizing pattern. Unless we point to 3 loads that were at least suspect or over-charged... or something like that.
This one by OP is, well, not circumferential. Looks pretty axially aligned to me. And not in the same spot.
The 2 examples you cite, don't point to any problem with the Lapua's bottom "right-angle" corner either. The failures are up away from that area. So guess I don't see a generalization there on Lapua construction down at that corner...
