All ammomakers have dropped their QC a notch or three.
Especially it seems the stuff they flog out through WalMart. Wally can sell everything they put out and does not take returns or complaints on ammo. Once the MBA's figured that out they cackled with glee and proceeded to increase profits.
I have even seen bad batches of premium ammo. Buy one lot number and test in _your_ gun, then stock up.
