I've run a few kegs of Titegroup through my. Some law enforcement kabooms have been blamed on bullet setback from clearing their service weapons every night and then reloading the same round or two into the chamber over and over, causing the bullet to be pushed a little deeper into the case. Little differences in seating depth, or more accurately, the room you leave below the base of the boolit, can make big differences in pressure and velocity. 40 S&W are very high, putting it in the magnum category.

Garym1a is right about WST being too fast for full power. There does seem to be a shortage of data for cast boolits in the.
Nothing wrong with that, but my 3.0g Clays load 800 fps makes me feel like I am shooting a 9mm instead of a 40. They also state 3.9-4.3g of WST, but those look like "powder puff" loads in the low 800's. Looks like 5.5g will get you in the 950's with a good safety margin while 6.0g will be pushing it 1000 fps. The Hodgdon website for 180g lead says 5.5g to 6.0g of WSF. Just no need to push that hard when punching paper. My pet load is 5.0g Unique, although I can safely shoot up to 6.5g. That leaves a part of the vertical section sticking out of the case so make sure your bullets pass the plunk test if you do this or seat the bullet deeper (to the edge of the cone) and back off on the powder by about 0.2g to start with. I've used 180g lead data for the Lee 401-175-TC which I seat to 1.135". I have not tried WSF yet in it but it should be great for full power loads. 4.2 gr of Bullesye gets it a little more zip. Very soft and fast where speed is the game.
