Hi
My name is Ron I’m new to this form, I would like to share this information.

FPS 1060
Load # 2

Load #1
Powder Clays
Grains 3.2

DISCLAIMER on his behalf, these loads can and do create squibs and can damage the barrel on the next shot. Ruined a perfectly good barrel with this exact combo.

Thats why I like to use Trail Boss in my subsonic loads. A full case of powder ignites and burns much more uniformly and efficiently.

Why do we need subsonic 223? For suppressed weapons? Sorry for the stupid question.

To keep the bullet from going trans-sonic and producing a "crack" as the bullet breaks the speed of sound. It never hurts to ask questions.

A lot of people like quiet, low recoil shooting.

Can't see it. Why is it nobody ever post "I done something stupid today & trashed my gun."?

There is way to much pressure there to stick a bullet.

sometimes they do, but usually they don't because they're too embarrassed

do you have any support for your claim or are we just supposed to take your word for it?

I'll work on getting you more then I say so.

I have to ask tho. Why would anyone put in another round & pull the trigger? I have stuck several. I do it do I know at what point it happens. There has never been the question was that the one.
