Matt Kline shot this beauty on June 26th 2005. The target measured 3.195" and went on to stand as the 2005 group of the year in Pennsylvania. It was only .044" bigger than the current worlds record of 3.151" held by John Voneida.
An animation of this target showing the sequence of bullets arriving can be seen in the history and information section of the website, under "3s club" (groups under 4"). Check it out.
Nice shooting Matt.
