Hodgdon Data Manual #26 (1994) shows Win. 231 for 155 gr. Jacketed bullets ranging from 5.1 to 6.0 gr.
The 40 S&W is a high pressure round. Seating depth on the bullet can seriously affect operating pressure. The 40 Smith is essentially a "short" version of the 10mm, and the case capacity is pretty critical with respect to seating depth and operating pressures.
You can check your chamber for "support" by removing the barrel and dropping a live round into the breech. Check the feed ramp to see how far it cuts under the case and into the web. My spec drawing doesn't show the web thickness for the 40 Smith. The other "support" issue to look at is how tight the case fits in the breech.
Glocks are "throated" and the case fits very loose in the breech. Makes for nifty feeding, but poor support of the brass. Also, the Glock feed ramp is cut deeply for feeding reliability. That's why Glock voids it's warranty for reloads, and why most powder mfgs. warn about "unsupported" or "partially supported" chambers. It's about as close as they can get to saying "Glock" without getting sued.
The 40 can be a fussy round to reload. Seating depth is critical. Ensuring that the bullet is adequately crimped into the brass so it doesn't seat deeper from recoil while it's in the magazine is important.
Personally, I like bulkier powders for the 40 Smith . . . like Hodgdon HS-6 or HS-7. These powders burn slower and develop a flatter pressure spike. Accordingly, they use about twice as much powder -- up to 9.8 grs. for 155 gr. bullets. A flatter pressure spike is safer when shooting semi-autos with partially supported chambers.
Still, the 40 is one of the BIG culprits in Glocks blowing the web out of reloaded brass.
I sold my 40 Glock and got a fully supported chamber in a .357 magnum S&W K frame revolver. 45 ACP is a lower pressure caliber for reloading.
But people reload the 40 Smith all the time. And the load books provide data.
Oh yeah, most reload component mfgs. provide load data online. M.D. Smith also has a reloading page:

www.accuratereloading.com is mostly for rifles but a good reference too.
