I've been shooting it in 9mm, .357 Mag & .45acp since they all came out decades ago.
I've never had a single problem with any of the thousands of rounds I've shot of it. Ever.
I just received yet another 1,000 round case of it in 115 grn 9mm from Bereli.
I don't need to collect any more 9mm brass, I've have more than I'll ever shoot out as long as I'll live so for match use, I've just been shooting Blazer aluminum for a couple of years now.
I think the folks that bash it must not have really shot it & are only furthering the urban legend that it's trash. It's not.
