so that others may learn from my mistake. I am used to shooting .22s and 9mms. I have not up until yesterday owned a pistol. I was given a .357 Ruger Blackhawk SA revolver by a family member as well as some ammunition. I decided to go out back and fire off a few rounds at a makeshift target. (In the county and nothing but woods behind me for miles) I did not wear hearing protection because my logic was that I was only going to fire off a few rounds. After the second shot, I temporarily lost hearing in my left ear. No pain, just can't hear much. It was very stupid on my part because I knew better. That was this morning and I still do not have full hearing in my left ear. I had never shot a .357 pistol before, and knew it would be quite loud, but I never thought it would have been THAT loud. Lesson learned, I purchased ear plugs and ear muffs for the range.
