What I plan on doing is developing a high velocity 9mm load (the legend really is a .355 cartridge IMO) to see what I can get from it.

Thinnest most prone to crushing brass I've ever used for a cartridge that size;
in over 700 rounds, I've never crushed a neck (much less a case.
But then... I've have never had any problem w/ 32-20 either.
Maybe same reason I've been married 53 years.

I just got back from testing some 115 gr 9mm test loads--I was able to achieve over 2900 fps and 2170 ftlbs KE at the muzzle while the group stayed together pretty well, and I believe I found a good node and will develop further. There's a discernible velocity point (2,850 +/-) when felt recoil kicks up a notch from softer recoil loads, but that's also when the groups tightened up noticeably.

You are a stud among studs. It's flimsy brass, no two ways about it.
