What has worked well for me:
9mm: (All loads shot through a Walther P99c; barrel is 3.5" with traditional rifling - if you've got a longer barrel, you may be able to get similar velocity with less powder)
124 grain Berry's plated round nose over 5.0 grains of Unique, 1.15 OAL, ~130 PF.
124 grain Montana Gold JHP over 4.7 grains of Unique, 1.075 OAL, ~130 PF.
124 grain Montana Gold JHP over 4.1 grains of VV N320, 1.075 OAL, ~128-129 PF.
115 grain Hornady XTP over 5.4 grains of Unique, 1.08 OAL, never chronoed, but was nice and accurate, no pressure signs.
The reason the JHP and XTP loads are so much shorter in OAL is that my P99c has a fairly short chamber, and in order to pass the "plunk" test, they had to be shorter. If you're loading for a Glock or similar, you can probably go longer with those bullets.
