What you call sandbagging I call a method of practicing to improve your performance at the national level. I've heard alot of people say they shoot MBR locally and HC at the BIG shoots. After shooting out to 45 yards (still 50 yards in my area) those 35 yard shots won't intimidate you. Its more of a head game than any thing. Maybe this guy practices twice as much as you or maybe he is out in the woods practicing judging distance every day and thats why he did well. In my opinion it doesn't matter what class your in, if your a good shot you will do well. The guy that won HC two years ago won MBR last year (National Triple Crown). If the guy you mentioned finished in the top 10% of HC, he would probably finish the same place if he would have shot MBO.

I mentioned above that it was a head game. Its a head game that you are losing because your letting it bother you. Relax, forget about everyone else and shoot your best. Thats all you can do.

AS far as I know he hasn't done anything illegal. The only stipulations in the rules are about going from pro class to amateur.
