Dennis - your 9.3x74 seems to have a very snug chamber neck with is nice and conductive to accuracy. I would keep an eye on neck wall thickness though - or stick to the .011" brass. As-is, it appears Hornady brass might be a bit snug, which can boost pressures. You know this, however others might not, which is why I mentioned it.

Of course, as brass is fired, it work-hardens. Work hardened brass is why we get neck splits - which is caused either by firing, then sizing, loading and firing, or by over-working the brass with undersized dies. Properly annealed brass can be blown out or expanded with a plunger straight, ie: .35cal to .50 cal., without cracking. It was how I made my .50/70 brass out of .348 brass. Hardened brass, on the other hand, will split every time.
