Maybe just me, but not worth the price.
buddies of mine experience that same deal on fire forming brass. Several were loosing one in five cases. Now the ones still shooting the .243AI are using 6mm cases with the shoulders pushed back. The case shrinks about .035" to .045", and in the end the necks looses out. These guys seldom loose cases anymore. You could also use 6.5x55 brass or just about anything longer than the 51mm case the .243 uses.
As for Hornaday brass, I think it's a little softer. All I've used is in .223, and (to me) it seems to be formed slightly better than most Winchester brass I've used in that same caliber. Blackhills was abolutely the worst I've ever used! (it's made by Winchester)
