i hate to be disagreeable, but shooting inside my house is surprisingly quiet, i accidntally shot a snub-nosed 38 loaded with hydra-shok in our small bedroom, it was loud but absorbed by the carpet/furniture etc, IT DIDNT EVEN WAKE UP THE WIFE OR CHILD UPSTAIRS, i was amazed at how quiet it was, so i had to do a lttle experimenting, waited til noone was home, set-up a target outside in my pool area, and did a couple shots from the middle of a carpeted, furnished room, out the window to the tarhet one story down
38spl,9x19,40cal all suprisingly quiet, no hearing protection required, all the sound is immediatly absorbed by the insulation of the carpet and furniture
357mag had a little whop to it, but not dis-orienting at all, if you have the opportunity, try it for yourself, youll be very suprised
on the other hand, when i need to test a couple new pistol loads, ill open the window in my basement(no carpet, no furniture) and shoot at a trap box, its super loud down there, loud to where it shocks your body(earplugs def required)
i thinkall if these rounds discussed would be easily tested for yourself, just dont tell the wife, but the neighbor likely wont notice what your doing, if they ask, you were just testing some primers to see if they were seating correctly
