I had two issues. One was an issue with the plating, which was a freak deal I believe. That said, if SSK would have tested The chamber using a dummy round, they would have caught that before it cost me extra time and money. The second was SSK not providing me with pertinent info in the beginning. I think it'll be fine now that I've just received my RP brass, though I haven't had time to do more than unbox it. I think SSK's customer service is\was lacking, but I've done the tough part (the teeth pulling to get the info). Just know you MUST use RP or Hornady brass and have to seat the bullet in further than with their older chambers.
Other options are the 358 Bellm and maybe the 35 Rimmed using 303 British cases.
But for the grace of God, there, I go.
