This online "postal match" has been in continuous operation for over 6 years. Funny part is, different forums have a postal match come along, everyone "oohs and aaahhs" about it, then it dies off after a couple months. The AirGunHome.com match does not involve mailing anything and has been constantly run, even if lacking in participants at times.
So, if anyone is looking for an online shooting match (can be done indoors in the cold months if you have a pistol and 15 feet of shooting space)- there is at least one not going anywhere...
