10mm Suppressed ?

Captain Obvious chiming in here…..

slower powder burns slower. The reason they burn slower is that smokeless powder burn rate for practical purposes is determined by two things

Coatings and composition that retard the combustion

Amount of powder compared to the case volume and resistance it takes to push the powder produced gasses through any neck restrictions and resistance of projectile movement

if you take smokeless and burn a pile in the open, it will spit and sputter (DON’t try this with black powder)

restrict the gas escape and you accelerate the combustion process. The more it’s restricted the faster a given smokeless burns, which burns hotter, which burns faster. This is the reason a heavier for caliber bullet takes less of a given powder than a lighter bullet.

so, to get the most complete burn you want the fastest powder without too quick a burn which could cause dangerous pressure levels

This is correct, to a degree. In this situation, it’s very likely totally correct. Going to Blue Dot is going the wrong direction.

I used Blue Dot with excellent success in 10mm, but the cases were stuffed full to the point that the powder was compressed. In that situation it gives excellent velocity and clean burn. Unique does the same thing in other calibers.

When you get to burn rates slower than, say, AA #5 cleanliness of burn depends on load density. A given powder may or may not burn cleanly depending upon application.

To the OP....Read my post #27. Then read it again.

I have used blue dot in .40sw, 10mm and .357 mag. It just isn't my favorite powder. It MUST be in the upper pressure range to get anywhere close to a complete burn.

Maybe it is better used in magnum shotgun shells which is what it was designed for. I certainly would not be running it through my can with light subsonic 10mm rounds.

Yup. You have to get to know a powder to know how it works, when it works best and when it won't work at all. I went through a pound of Ramshot Competition loading everything from powder-puff .38S&W to fire-breathing .40S&W loads just learning its personality. It's good for situations where WST is too hot and Nitro 100 is too fast. Blue Dot is great for magnum handguns, magnum shotshells (I'm told), and rimmed revolver loads in fixed-/solid-breech carbines. Blue Dot in a heavy bullet .44Mag lever gun is magical. Just don't run it below top of the load data and expect a clean burn.

The heaviest I have seen is this hard cast 230:

Though that is ammo. Not sure where they get the bullets. For subsonic I would certainly think the 220 or 230 would be the way to go, depending on reliability and recoil once shot. Lighter and you might as well be suppressing a .40 instead.

that’s what I was getting at, any lighter and you should suppress .40. Not that’s I’ll get a suppressor any time soon. Don’t want to get on that list! lol
 
Welcome to the world of cans and chronographs….. It is about energy with a roof on velocity, the sonic roof. You increase the weight, then increase it again…My 300 BO load is with 230g and my 45 ACP is with 252g.

By the way you can go on line and look up your sonic threshold by your altitude.

I love a heavy slow bullet! especially out of a handgun. .45 because they don’t make a .46

Have you tried power pistol or BE 86 ?

I have not as of yet, trying to use the powders I have at the moment.
Moving to a heavier bullet, as advised, was a must. As was moving to a faster powder. Went from AA9 to Alliant Sport Pistol.
I chose ASP over W231 due the ASP having a flash suppressant, not temp sensitive and allegedly created for coated bullets.
