Is it me, or are BP and BP sub options becoming limited?

Good Morning Pards,
I have  an order of Black MZ (made by APP) coming from Sportsman's Warehouse  at a very attractive price including that silly "hazmat".
This is not a paid announcement.
I have used BMZ and APP both and the difference i saw was BMZ is black and APP is grey otherwise it seemed the same in my percussion revolvers. I have not used any yet in brass cases so i can't speak to that.
Respectfully submitted
Bunk
