Ummm, well if I didn't already have my $200 and some odd Redding special order 17 AH dies I had to buy a few years ago to make my 17 AH work, I could get the 17 HH dies MUCH cheaper and get a factory gun that shoots adequately much cheaper than my Ruger 77 Hornet rebarreled with a Shilen cost, and be making brass from 22 Hornet now and moving on. I'd call that smart business. The performance is basically the same between the calibers, so having a preference is ridiculous. I doubt you'll see many AH's built anymore - the masses will go HH, and the masses are where the $$ are. This is to turn shooters TO the HH, not keep AH shooters happier with cheaper goods. If they mad eit like the AH, folks with those dies, brass, etc. (although a small number of shooters total) would never be buying anything from them in the die/brass line. The brass problem will go away with their next run of brass, I'm sure. Someone REALLY messed up on the first run.
If they built it just like the AH, they wouldn't be selling dies to anyone who had them already. Same with the 17 FB vs 17 MkIV - nobody gets a custom MkIV built anymore. And the MkIV IS based on the 221 Fireball also. MkIV dies are getting hard to find in stock like they used to be, and 17 AH dies are getting clearanced out now.
Take any caliber that wildcatters were successfully using already - 17 AH, 17 MkIV, 22 Varminter, etc., and look at the eventual commercial equivalent - just enough change in dimensions to make you want to just not bother with all the custom costs, fireforming, necking, etc., and just go factory.
