it is a freaking DISASTER to have to fire your unsuppressed weapon. Sure, you might have saved yourself from the immediate threat, but then you're going to have 10-100 more who know of your armed presence and desperatelly want and need to kill you, to get your stuff and remove you as a threat. If you, however, know to be holed up during daylight, have NVD's, luminous sights, and a silencer, and you manage to kill them all with the first few shots, before they can even fire. nobody heard your silenced 223's more than half a mile distant. if you were able to use your subsonic 22 unit for the job, nobody heard you beyond 50 yds. Sure, maybe you have the issue of crows and buzzards revealing the bodies, but at least you'll have time to strip them, be gone from the area for a day or more, hide your tracks, etc. If your shot was at game, of course, you'll be hiding everything very well, utilizing most of it, burying the offal, using it as bait, etc. the very idea of NOT having a silencer for shtf is retarded.
