I never heard of them but I did look and my one problem is that there prices for once fired 44 special is higher than Starline 44 special new.
Almost all of my pistol brass was purchased new from Starline. I would check out the price difference between there’s and Starline and unless there's a real savings difference (30% or more) go with the new.
The one time I purchased once fired bras was 308. I was told it was fired only once. On the 5th round that I fired I had a case head separation and that was with a medium pressure round. I pulled all the bullets that I had loaded and found that almost everyone had a ring inside the case from stretching.
I don’t trust used rifle brass unless I know who and what it was fired in.
