I use 180gr. Rainiers on top of 5.5gr. N340 loaded to 1.130 and crimped "just enough" for a target load. Note the max is 6.1, only .6gr. over the min. They claim 1001-1109fps with a 5.5" test bbl. This is the minimum data for Viht and loaded a little long, but I still get about 900fps. out of a stock G27. No bulging. 155gr. XTP factory loads clock 1040-1100fps. Most of the Viht stuff is clean burning, some is low flash too. This stuff works well, and I bet the 3N37 would too (which is my favorite 9mm powder). These loads are pretty accurate, but I don't have much formal data on it yet (I don't shoot .40 all that much). I can hit coke cans at about 25m or so no problem and it cycles fine. If you find it is too weak, just work it up. Slowly.
With .40, it can't really be loaded all that hot, not safely anyway, and it can't be reduced much either. It also can't be set back much without increasing the pressure dramatically (which is why I load 'em long). It is a chopped down 10mm, which is the one that can be loaded hot. The .40 was a specialty cartridge, but it isn't treated as such anymore.
