Primer Blow Out with NO Over Pressure Signs?

[Great-Kazoo]

how many times has that brass been used? I didn't see or over looked that info. With loose pp's it could be the brass OR primers used. I'd try other brass, using same primers, and load data. IF it happened again, i'd be calling the mfg. maybe they had a load of mismarked LRM's ??

Sorry, brass is once fired, range pickups from brassbombers.com.

Looking at the primers again, they are all marked WLR for Standard Loads.
