Been loading .45 for a while. Used lots of different powders. Currently been using TiteGroup, Bullseye, Clays and I think one or two others for jacketed and WST for cast lead(which I dont want to shoot through the can).
Trying to quiet down my suppressed .45 loads a little bit without sacrificing velocity.
Reading that a faster burning powder will be quieter and single base powders are preferred due to their supposed cooler temperatures they should in theory be quieter. Titegroup is pretty fast IMO, but is double base. Seen N310 recommended as well as Solo 1000 which are on the top end of the burn chart. Any opinions of whether I should just stick with Titegroup or try one of the VV powders or Solo 1000? Titewad is up there with N310 in the speed department, but not sure on single base, and I have seen a ton of that locally for cheap.

Re: Quietest powder for suppressed .45
I have got my best results loading with Unique for 45acp.
6.0grs stays just under 900fps.
Functions all my 1911's suppressed.
Works great in my MAC too.

Re: Quietest powder for suppressed .45
im not worried about function, I have 6 or so loads with various powders that function. I was looking for one that is the quietest. Unique is pretty slow compared to the rest I am looking at, which, in theory, should be louder than a faster powder. Its pretty hard to get .45ACP to go supersonic so also not terribly worried about that.twodollarbill wrote:I have got my best results loading with Unique for 45acp.

Re: Quietest powder for suppressed .45
As you say, fast burning and cool seems to work better for quiet loads. I already load Solo1000 for all of my IPSC/IDPA/steel/3-gun matches in .38 Spcl, .40, .45 & 9MM, and also apply it to any 9mm rounds intended for suppressor use. It is the quietest of anything I have tried so far, but I don't have a .45 can yet. Solo is a good match for .45, it is inexpensive and used to be easier to get than VV. It meters well from my Hornady, but sometimes takes a few throws to settle down. I learned to start the powder throws above intended charge weight and titrate down to the goal. If you can find it, I'd recommend trying at least a pound of Solo1000.
The one problem with Solo is lot to lot variance is high, as much as .5 gr in pistols, so if you stick with it you are better off buying 8# jugs or higher. I've been thru ~48 lbs of Solo100 so far, and see no reason to change.

The natural progress of things is for liberty to yield and government to gain ground.

Re: Quietest powder for suppressed .45
Titegroup works and sounds the quietest to me.
