Thanks Angus, dad found his gong material in a pile of old scrap deck-plate at work. It was only 1/4" stuff so the "7's" were punching through even at the long distances but it was still easy to hear and see the impacts.
Have at it Outlaw! It is a pretty good time. I usually like to shoot by myself but a little friendly competition to test your skills now and then sure is fun and I like learnin bout how others do things
