I only shoot, hunt or fish, after the first day of the new moon, and only then AFTER I have taken 3 drops of fish oil, beat my dog, insulted my neighbor's horse, and ran around my shop three times in a coon skin cap, and breech cloth.
I always check the chamber. That's not a ritual, it's just smart. Then I do what ever I intended to do. I've been shooting the same guns so long, I just do it. I know how they shoot, where they shoot, and why, so there's not much to obsess over.
I do however become irritated if I'm with someone, and they start going thru some damn ritual before goin into the woods, or firing at the first target. It gives me the idea, they may or may not know what the hell their doin.
