I shot for years without protection and we used to laugh about our ears ringing.
That is obviously way more than just one or two shots.
So, yes. A single shot can hurt. Especially from a really loud gun.
No doubt an Encore Pro Hunter is a loud gun - I believe these are pistols that fire high-powered rifle rounds, right?
All I said is that one or two rounds of plain old 9mm or 45, outdoor is not going to cause hearing loss. Not rifle rounds, not 357, not 44 magnum, not even 10mm or 40S&W.
In fact, is there ANYONE
here who has NEVER
fired (or stood next to someone who fired) even one round of 9mm or or 45 without hearing protection??? Give me a shout out if you have "virgin ears".
