Didn't Hobie buy a box of loaded TenX 45-75's and the brass was made by Bertram?
That's right (got two boxes but had ordered five). They couldn't get the brass from Jamison (who's filling military contracts) so they bought Bertram and their prices went up accordingly. I was not pleased with that but took advantage of having some of the Bertram brass to examine as I would NEVER pay that price for brass which, based on my experience with other cartridges, isn't as good as it should be. IME, the Bertram brass is about like the S&B brass, quality is inconsistent, some is brittle (it tends towards brittle). Shooting it the first time usually tells the tale but it is then too late to anneal or take any mitigating steps to save it.
