It's perfect for 357. I burned a lot of it in my 357s.H110 is to slow and bulky for 9mm. It's almost too slow for 357 Mag.

Fire ball, very high velocity, very accurate, and a concussion that wakes the dead. What more can you ask for?
I totally agree with the 9mm being too low capacity.
Google "Secondary Explosion Effect" (S.E.E.).
Powder needs resistance to burn properly. A 9mm bullet doesn't have enough mass and friction in the bore to build up pressure with slow powders.
It’s funny you should say that because after shooting my max H110 loads from a 6” revolver, I was a little disappointed in the velocity and a little taken aback by the concussion and fireball. They kicked butt from my lever action, but not so much from the revolver.The fireball and concussion is due to it being a touch too slow. A modest % of the powder charge burning in open-air in front of the muzzle, after the bullet has already left the barrel. No doubt its a common powder for magnum revolver cartridges. But I have found I can achieve similar velocities with slightly faster powders and then I don't have all that obnoxious muzzle blast and flash. If I was loading 357 Magnum for a carbine then H110 would be a good choice, but for a pistol I find it too slow and use other powders. I save H110 for 410 shotgun shells and 450 Bushmaster.
It is true in a way. Modern smokeless powder's burn rate is proportional to pressure. If you can't generate pressure the powder burns poorly. (Pour a small line of H110 out on concrete and light one end it will take seconds to burn to the other end, no pressure) H110 works in 357 Magnum because you can have enough powder (surface area) in the larger case to generate sufficient pressure to get it to burn properly. In 9mm you can't get enough H110 (thus surface area) to generate pressure fast enough to get the pressure up before the bullet exits. Also H110 tends to work best with heavy for caliber 357 mag loads that are typically heavier than loaded in 9mm.This argument doesn't hold water. The same could be said of the 357 Magnum, since they use the same bullet weights.
Slow powders like H110/296 are also used very effectively in the 22 Remington Jet, 327 Federal Magnum and 7.62X25 Tokarev, which have much lighter bullet weights.
May I ask your preferred 357 powder? I’ve been thinking about AA#9 but I think it might be a touch too slow also.

Sorry. Wasn’t trying to derail. It’s just the first time I think I’ve heard someone say it isn’t optimal for 357 and it validated what I experienced.2400 is THE powder for 357 Mag. Others around the same speed work but it has been the benchmark for years. I believe the original round was developed with 2400. Yes, good results can be had with other powders all depends on if you want true "mag" loads or something else.
But this belongs in another thread not a 9mm thread which H110 is not the powder for,
