I too have shot about 6 boxes of Monarch and have no complaints except for the unusually small boxes they come in. Simple solution that I take is just transfer the rounds into bigger plastic storage trays that I have been stocking up on for when I get into reloading (fingers crossed hopefully soon).
Still pisses me off the you absolutely cannot fucking find 380 rounds anywhere. I've got my Colt Mustang and the poor thing is just begging to be played with.
That is odd that the box is really small. Didn't really think about it until you posted that. And I am with you on the 380 ammo...Its no where to be found...at least at a reasonable price...hehehe.
