At some point I want to buy a legal suppressor, one that can muffle .22 and .223. After that, I want a suppressed .45-70 falling block. If it has to be slow it might as well be really, really big. Imagine a 500gr hardcast cruising sub-sonic from 500 yards. Don't think you'd hear that. As far as poaching, not really necessary. Even if you must use a firearm, some are very quiet. I'm back on my 60gr Aguila SSS kick, found out my Marlin 925 shoots them without a barrel change. If it is louder than my .177 air rifle it is not by much, I can shoot a tree 100 yards away and the most distinct noise is the hit on the tree. Suppressed it ought to be awesome.
