Though a good question, that proposition is both depressing to think about and impossible to answer. For instance, when I head to the skeet range and plan to shoot, maybe, 3 rounds, I invariably take a different gun for each round--and most often use them all. I could probably be a better shooter if I shot the same gun all the time but there is no point to it, for me. I enjoy restoring and working on the guns I pick up here and there as much as I do shooting them. But a great post, nonetheless. Gil
