I shot my second Steel Challenge match yesterday. I missed way too often but my problem is most of the time I can't hear the steel ring. So I don't know that I missed. I am 69 and I know my ears are lacking in the higher frequencies. I am using the common dark green Howard Leight light electronic muffs. I can adjust the volume but that seems to bring the backround and the shot volume up or down more or less equally. Are there better electronic muffs? I wonder if they cancel the shot noise and then there is a delay going back to normal so it also cancels the steel ring. Ideas guys please.
