I'm sure we all remember the movie "Dumbo" where the little elephant calf with huge ears first finds out he can fly, but only by holding onto a "Magic" feather. Joe B's BS lists have had the effect of taking away a lot of "Magic" feathers. It is very hard to be completely honest with ourselves. Nobody wants to admit to ALL of their failures. Let's face it, doing so hurts, and if it hurts we don't want to do it again, because it may hurt again. So, when we are pursuing an activity we find pleasurable (cast bullet shooting) and our results do not measure up we look for an excuse or reason why. This is especially true If you feel that you are good at the particular activity.
Americans are some of the worst BS'ers about why the shot didn't hit the target, just ask any guide or outfitter. They have heard them all. Our greatest problem with shooting performance in this country is equipment. There is always a better piece of gear that will solve all our shooting problems. Bench rest shooters have to be even more susceptible to this phenomenon, after all they usually use the most accurate rifles, sights, and loads they can get their hands on. So when the bullet goes wide of the group or the bull and you failed to call it what or who do you blame? Do you blame the rifle, the sights, the bullets, lube, bore condition, a wind variation you failed to notice, this list can go on for a long ways, but ultimately the fault lies with the shooter, the reloader, or the bullet caster.
I submit that those of us who have gotten "peeved" with Joe B over the content of his BS lists are mostly upset because he is taking away our protection and making us examine ourselves more than we are willing to.
