I've found, if one cannot shoot well under a controlled environment..........one cannot shoot well outside of one.

Fundamentals is fundamentals. Ya got'em........or ya don't. A benchrest shooter does not automatically equate to a field shooter. But, the basic fundamentals translate exponentially from bench to field. I've seen it time and again.

I teach folks to shoot in a comfort zone. Then I take it away. Those that shot well in calm tend to shoot better in chaos.

Those that scoff at small groups usually do so because they can't themselves.
