Has anyone built a suppressor for a beowulf?  Other than the large diameter it seems like it would be pretty straight forward, not a high pressure round or a ton of exhaust gas.  Anything else?

Is this for a semi or bolt gun?
You should be gtg w/ a 1.75"OD x 10"-12"L suppressor.
60* cones will do fine, although you could get away w/ less baffles if doing a K (reflex or integral design would be great), and get at least 10 of those cones in there.

A welded design would allow for thinner wall thickness (less weight), but Ti and Al can help w/ that, too.
Depending on what powders you're using, you might want to be able to service it. So, a threaded design would be appropriate, in this case.

Are you looking to buy everything or turn the parts yourself?

Great reply, thanks.  

Running a standard AA 50 Beowulf upper.

Looking at heavy for caliber cast subsonic rounds.

I see cans meant for 50 cal use, seems like most of them are for BMG etc, looking at the practicality of putting one together more tailored for this round.  Would certainly prefer to use as much prefab as possible, have access to a lathe and some basic machining tools but time is money and prefer to purchase.
