 Subsonic ammo through a DE?

Has anyone tried working up a subsonic load that will run in a Desert Eagle in either .357 or .44?

I've got an idea I'd like to try out, but thought I'd ask around first. I wonder if some combination of bullet weight and type of powder could be found that would work with this.

It doesn't seem to be impossible to me. You have to stay under 1200 fps to be sub sonic. With heavier bullets, long barrel and slow pistol powders the suppressor will help work the action.

I say go for it and let us know how it works.

1200 is going to be supersonic (unless it's over 140 degrees F outside - check the speed of sound calculator).

I was thinking something more like 1050 fps (subsonic as long as it's warmer than 0 deg. F).

I have a wild idea to chop and thread a 10" DE barrel and put a subgun can on it. It wouldn't be all that effective if it would only run with supersonic ammo, though.

I'm curious which would be easier to work with, .357 or .44.
