I have lots of guns and practice with them every day. ALWAYS on my mind is 'what good is this going to do me in a SHTF situation' The problem is noise. I'm told that even one shot with most rifles or handguns will do a lot of damage to your ears. I use calibers like .300 win mag rifle and .454 casull for handgun. One shot with those hurts the ears and most tactical situations you probably wouldnt have time to put on hearing protection. So basically... guns are useless unless your already deaf ?? or how many shots with no protection can a person actually tolerate ??
