I've bought the Jamison brass, before they changed hands a few years ago. Was one of those times when there wasn't anything else available. Got it from Graf's and their price was a bit higher than the Remington (out of stock) at that time. Their quality then was fair, compared to Remington but when you ain't got nothing else to use...
So far, I haven't seen or heard of any bad product reports out of the new Jamison/Captech International group.
I'd like to see Starline get in the .357 Maximum business too.
