Accurate 2200???

[Sharkbite]

Anybody tried to work up a subsonic load with 2200? I found 4 cans and snapped em up. The powder drought around here is killing me.

So far ive got 10.5-11 gns with a 208 Amax to function the gun with no signs of pressure. Its pretty dirty though. After recovering the cases from the snow in my backyard the necks have a pretty sooty look. Primers look good and no extractor marks from the BCG moving to fast

Comments... Suggestions....experience.

...Its pretty dirty though...

So dirty that it may interfered with reliable functioning.
We were experimenting with lighter bullets in the Blackout/Whisper.
Heavy bullets may provide sufficient pressures for cleaner powder burns.
In our testing, there was so much unburned powder that chambering and extraction were compromised.

It's still a good powder to have as it works in lots of chamberings.
