In all my days of shooting, I have only purchased 1 box of Black Hills ammo. It was in 32H&R Mag. Ended up buying from a retailer on the internet.
32H&R mag has been very hard to find at times and BH was all I could find.
The ammo was just as accurate as any other brand. Yes, they use Starline brass. I have lived in many states over the last few years and rarely if ever see BH ammo.
BTW, I learned many years ago to take everything gun writers write with a grain of salt and in some cases scepticizm. "BrenTen" immediately comes to mind.
