Uh, right... Why else do you think I was referring to the NFA?
And I'm not looking to be a "deer assassin." Just thinking that a little less noise on the hunter's end might be a bit easier on the hunter's ears... If you could take 25-30db off it, you'd still have noise, but hey...
And the main point of my post is that anything NFA is not going to be legal for game hunting (deer being "game animals") in any state I can think of.
You would have to get laws changed, at the state and federal level, to be able to use any form of a supressor for game hunting. That means deer, elk, migratory bird, or any other form of hunting that involved "game" animals.
For non game animals, such as hog, havelina, and other varmint type animals, it is legal to use supression devices. I know several people in Texas that religously hunt hogs with suppressed AR's because it does make the hunt more enjoyable, and the suppressor also acts as a hell of a flash hider when hunting at night.
But my interpretation is that you are looking to design and implement a device that you don't consider a suppressor, but will still be considered a suppressor in Big Brother's eyes, to hunt deer - and that isn't happening unless you have a massive amount of political clout and have the ability to get state and federal laws changed.
If you do have that ability, you will be my hero. I am a huge fan of suppressors and would love to have considerably looser restrictions and laws on them personally.
