What is the .40 S&W?
JimP:
The .40 S&W dublicates the 10mm "FBI Load", which was a reduced recoil 10 mm load developed when Agents complained that recoil of the 10mm, even in their 40 oz. 1076's was to much...... true, 200 grains at 1200f/sec is going to shove ya, but it's not like it's a .44 Mag or anything- some of the energy is bled off by the slide of a semi-auto......

I don't know whether or not you're crazy. You'll have to ask Mrs. Jesse for a definitive answer on that item. Better not to ask. I would never ask my own lady that question, for fear.
Now, back to work:
As it happens, 10mm = 0.3937 inches [which clearly ain't .40 cal. Just like you said up above.]
But then, .38 cal and .357 cal both fit into the same cylinder of my Model 19 S&W. And they both go through the same barrel, just alike.
For fun in slow times, you could get out your micrometer and measure the diameter of a .38 caliber bullet. It isn't .38 caliber and it isn't .357 caliber. It's a whole something else different.
So........ammo-wise, you're not crazy.
It's the ammo designers, manufacturers, and----most of all----the AMMO Namers!!!!!
They are as crazy as a gaggle of weasels.

I have two .40's a HK USP Compact that is my CCW piece and a Springfield XDm that I keep in my bedstand... Both damn nice weapons, the HK holds 12+1 while the XDm holds 16+1. While not as powerful as a 10mm you can get some JHP loads that are very effective. Both of my weapons really like the 165 gr. and 180 PDX1 from Winchester. There have been some good deals on bulk Speer Gold Dot and Gold Sabre from Remington online also... For practice loads I go with 8.2 gr of Hodgon HS-6 with 180 gr Speer TMJ.

For a load with W231 and a lead 180 gr bullet you'd need to start low, probably around 4 gr... I'd look around on some of the other sites and do a web search for lead loads for the .40... One thing to watch out for with powders like W231 or Titegroup is that is possible to double charge them because they are so hot that you don't need much powder.

Well, they call the .38 "thirty eight" ya know, even tho it's .357. Yeah, but there are a good number of intelligent, common sense filled good people in da shoot'n bizness.
