Excellent thread on this issue:

After reading in this forum about Dominion brass in .43 Mauser and since I took delivery of a 71/84 in the last couple weeks to include all the supplies to load this caliber..... including a bunch of Dominion cases... Pretty sure most everybody who has experience with this caliber already knows about this brass but for those who don't....
Also read something about these being ~cast~ and by cracky there looks to be casting voids on the headstamp area.
Fortunately, I have 40 pcs of Bertram brass and 40 pcs of Bell Basic Mauser base and about 35 pcs of Starline .45-90 converted with modified rim. I think I'm safe from using the Dominion cases.
