My club has grown to where we can host "sanctioned" NRA matches. To date, all of our matches have been NRA "approved".
Thus far, all matches have had all shooters grouped together...T/R or Open. It's a great group of guys and I enjoy the game, but it gets a little old when you can predict who will get the trophies before the match even begins.

So here's the question:
Is the use of classifications mandatory in sanctioned matches, given there enough shooters to form a class?
How many shooters does it take to form a class?

I asked this of the NRA competitions divisions, but never received a reply.

Thanks for any insight.
