Is shooting a tight group really that difficult?

Ted Biers

Ask that guy how difficult it is to shoot a tight group. I've been shooting for years and will likely never put in the time to accomplish the feat Ted has captured here on camera. In all seriousness, if it's that easy, please make a video reproducing Ted's results here and break it down step by step so I can learn how to do it also. If I've ever shot an MOA group at 100 yards, it's only been once or twice at best and even then only 5 shots, let alone 10 shots!!! Amazing, and yes, I believe that difficult.
