Lil gun, 2400, 296 or AA9, would work wonderfully behind a tough 158(XTP, Gold Dot) or a 180(XTP, HCSWC, etc.)
Thing is, you may not want straight up maximum velocity. Push 'em too fast and they'll act like a varmint bullet when they hit. Try to find a spot about 2/3ds-3/4 the way up the charge weights that gives you best accuracy. Then load 'em and be done with it.
They'll be going plenty fast, but not fast enough to blow up on impact, and they'll be going were you intend them to.
