I suppose the simple solution is to tell the clubs not to shoot USPSA anymore. It does not seem like the best solution however.
Even if you are absolutely horrified at the prospect of clubs that do not want high muzzle reloads having their say on the issue, there is one fact that you must realize.
THIS IS NOT GOING TO GO AWAY.
This will be a growing concern, and one that keeps coming up like a bad chili dog. If the BOD is proactive in how they run things they need to consider this situation. Now they may well determine that the loss of a few clubs is worth not meddling with the rules, or they may decide to give clubs the ability to require muzzle down reloads. But the BOD really should address this issue.
I run a club that is having some heartburn over this issue. We had a guy put one over the berm during a reload, and this really catalyzed the sport's detractors. It is true that the guy's finger had a lot to do with it, but the no-high-muzzle crew are using this as a stick to beat me with.
This does not have to be an issue based on fact and logic. When you run a club at a range, you are usually responsible to a Board of Directors or other governing body. I do wish that USPSA would discuss this issue so as a MD, I can have a better answer than the one I have right now.
