Ya know, Heckler, these days I'm just about the same way. I'd rather get my practice by going out and stump shooting instead of pumping arrow after arrow into a target. Or at least trying to. I've got a roaring case of target panic that only hits me when I'm shooting at targets.
Shooting at a leaf blowing across the grass or maybe a fungus on a rotting log, I can shoot like a world champion. Put me in front of a target though and I turn into a complete wreck in short order.
Stumping is a whole lot more fun anyway.
