If it was too loud for someone 6 lanes away wearing hearing protection, it was probably too loud for you to be shooting indoors.
Hearing protection isn't perfect.
As for as interacting with your fellow humans, it doesn't seem that you did anything horrible.
he was in lane #3 and I was in lane #7 so we where 4 lanes apart but still you are right it is a bit loud to shoot in doors. I do double up on the hearing and my muffs are some of the best rated I can find.
and Thank you
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
