With all due respects, I would recommend that we do not improvise. We should follow the rules which are evolving. I really enjoy shooting on etargets but we are still working some things out. I think the new 2020 rules are an improvement. Best wishes, Clyde the elder.Last match I shot with E targets, we were highly encouraged to watch the trace to the target with a spotting scope, to be able to identify cross fires. And as it turns out, I managed to cross fire- scorer said it was clear as a bell with no question to what I did. Otherwise, you are prone to getting a few "shot didn't register" calls....
