My apologies SEM.
I still haven't been able to find dies for them, so I believe you may be safe. This just came up as I was looking at 30-30, 30 Major (PPC Imp), 7.62x39, 7.62x40WT, 300 Hammr, 6.5 JDJ, 6TCU, 6.5x30-30, 30-20, 327FM, and quite a few others and comparing the cost to performance gains for reloading. The Herret has always intrigued me. I just don't have experience with that many forming steps, but would consider it for a performance boost. The TCUs are much easier to form.
