Does anyone use Trail Boss Powder for Subs?

[HotLead]

I have not seen any data on this, just curious if anyone has experimented with Trail Boss for subsonic reloading. Please share! :grin:

Will not work with the whisper. Use it for the .510 and 454. Just too much bulk there..

One can only use powders which reach 1000 fps. There is no way Trail Boss could do that in such a small case.

Yes, in the 308 and similar calibers, but not in the whisper's. You'll need a faster burning, more compact powder for the whispers.

I haven't tried it yet, but a friend told me that he shoots .223 subsonic with 4.5 to 5 grains of TrailBoss and a moly 55 gr projo.

It won't cycle an AR .... I'm not sure any .223 subsonic will cycle an AR.
