poor man,
Have you got or looked at a loading book? For that matter at the on-line sources?
Hodgdon H414 - I don't use it, but, it is used well in rifles - I don't think it to be suitable for the very small case capacity of the 40 (Assuming you are referring to the 40 S&W.)
Hodgdon Varget - I have used this powder in loading for the .223/5.56. Again, I don't think it to be suitable for the very small case capacity of the 40.
Hodgdon universal clays - I don't use any of the 'Clays'. Some are useful as pistol powder, others are not. I just stay away from them as I don't know one from another. If you loading book lists one, make certain it is the same one you are going to load with.
LiL gun - This started as a .410 shotgun powder. It is used in large caliber Mag loading (I have seen some information on it burning/cutting top straps in revolvers. For me the jury is out. I have used it in loads for the 300 AAC Blackout 'rifle' cartridge. Again, I don't think it to be suitable for the very small case capacity of the 40.
Look at 231/HP38, unique, bullseye, power pistol, HS6 or Titegroup. There are many more 'Pistol Type' powders that are suitable.
I suspect that you are searching for a powder due to the current insanity. I feel for you. But you've got to use powder that is safe.
