Some of you have read the thread about the The .50 Hushpuppy built by Delta Company Firearms LLC. This thread expands on that one somewhat.

I am designing a suppressor for the .50 Huspuppy and it will be built to handle cast bullets.

Most suppressor designs are suited for cast bullets because the suppressor acts a crud trap, catching any unburned power granules, bits and pieces of bullet lube and even lead particles. A lot of the newer designs built today are sealed units, so there really isn't a good way to go through them and clean them out, the recommended methods of soaking them and blowing them out with air will only work so long.

This suppressor uses a monolithic baffle stack. This means that everything is connected, the whole unit slides out at one piece. There are several advantages to this, if they suppressor gets really gunked up, the pieces tend to stick together and become almost impossible to remove, the gunk sort of "welds" everything together. Also, with contaminates moving at a high rate of speed, the clearances used to put all the parts together can knock them out of alignment, causing poor accuracy or even worse, a baffle strike with a bullet that could destroy the whole can.

The monolithic design, so far, has proved successful for shooting cast bullets. Some tricks are done to make the can easier to clean, after a long shooting session, you simple remove the front cap, slide the baffle stack out and rinse the whole assembly off. A wipe with a rag on the inside of the can itself and you're done. Of course, it is recommended to do this after every firing session to insure that things don't get out of control.

Shooting cast boolits through suppressors of any sort is a mess and generally not recommended by most, if not all manufacturers. Its a pity really, because cast bullets are cheap, as available as you want them to be and when bullet prices shoot through the roof due to hostile administrations, subverted governments, economic factors, the EPA or any of the other multitude of reasons,, use cast boolit guys can spend out money on primers and powder instead of bullets.:cbpour:

So far,it looks like I am on track. There are big calibers out there, that when run subsonic, will kill any thing that walks,crawls or swims with cast lead.

The cast boolit guys have sort of been left out by the suppressor manufacturers. Since I am an 07 Manufacturer, with an 02 SOT, I intend to correct that oversight. Of course there will be lots of trial and error and it may take awhile,but my goal is to develop a can that is fairly quiet, cast boolit user friendly and cheap enough so that you don't have to take another loan out to get one.

What'd' ya think about that? Let me know if you have any other ideas that could be beneficial, or even if its something you might be interested in. I'm all ears..

In the mono can I built I made a blast chamber out of steel That also created steel threads so they wouldn’t wear out. Instead of having to pull out the stack I just machined O-ring groves in the cap and body. Just remove the cap and slide the tube off.

In the end the mono core cans seem to weigh more and have less suppression I just make K’s now and thread the end caps so I can clean them. Even shooting full auto, they get pretty nasty but you can clean them up.

Using pistol powders (I see you are using trail boss) you can also shorten the barrel below 16” then make the suppressor permanently attached so you only have to have one stamp. This one is 16.125” with the end cap removed and super quite.

The other method I have used to keep it short is to have it telescope back over the barrel, so I cold add volume without adding length. It’s more work to build one this way but it is quite without needing a pool stick case to haul it around.

Those are some nice looking cans. Do you just make them for yourself or do you sell them?

The only suppressors I use with cast bullets are take apart cans obviously and the AWC Mk9 (mine is actually 45) for use with my UZI is quiet and easiest to clean. It's older spacer and washer baffle design - a bead blasting makes thing go much quicker.

What are the legal restrictions on building one for your own personal use? do you still need to pay the crazy fed tax & everything?

Yes, still got to poop out 200 bucks and hand it over to some lazy person on welfare and wait three months. The form you need is a Form 1.
