I know factory .40 S&W Federal 155's are around 1150 fps.
Looking at the load data, with a max load of longshot powder, hogdon shows I can get up to 1283 fps with a 4" barrel (Mine is a 5 inch barrel) so that will probably push it upwards of 1300 fps or maybe a hair more which is a notable increase in power over what most over the counter 40 ammo will do.
I know that 40 S&W doesn't have the case capacity as 10mm and 10mm is capable of a lot more so I am trying to avoid comparing it to a 10mm or call it something it is not, but the numbers exist for a mild 10mm load from the 40 cal. Hornady factory ammo publishes 1265 from their 10mm 155 gr.
I currently have a lightweight 14# spring in my XD Tactical because I'm running a 2 stage springco recoil rod in it, but if I ever run a few mags of the hotter stuff to see how they work or if I dust it off for HD duty again, I'll probably put the factory 17# recoil spring in it out of an abundance of caution so I don't damage or batter the frame.
I wouldn't feed it a regular diet of them, but I don't see a reason not to try them and if they are reliable, don't see any reason why not try it.
Does anyone knows why it would be a bad idea to load some up?
Aside from the longshot powder, I may also look at #9 and Enforcer if I can find some known good data for them since I have a few pounds of it sitting on my bench that I use in my favorite subsonic blackout loads.
The enforcer pushes a 125 gr Hornady through my 6 inch 357 at 1650 fps. And I haven't tested it through my 16 inch .357 Pardner yet to see what kind of numbers I'm getting through it. That's some really good powder too. If I can find some numbers on it with the 40.
