not arging ss but i have found it to be the other way around, but i haven't joined the ata as a new member since 1980. but i do know some pretty good sporting clays shooters who achieved master and they were placed in B unless a big shoot then it could be A. would like to know the results, keep us posted and once again congrats.
Fly, don't worry about your ave. yet. Just go out and shoot some small club shoots for your first 500 targets. More than likely at these small shoots they will give you a N/A for your first shoot. No Class as it were. After your first shoot your score will give you your class for the second shoot. You just add and reaverage all your scores until you get to 500, then you can go to some of the larger shoots with a good ave. so they can place you there. If you go to big shoots before 500 targets they will hit you with a A class in most shoots. It comes down to the rules at different clubs. So just go out and have fun at the smaller shoots and get some targets reg. and the rest will work itself out. You can still shoot at the larger shoots for targets only if you like, and want to go to some of the larger ones. Have Fun and Good Luck. Break-em all. Jeff
