next weekend, there is a PRS match in MO. It is advertised on tacticalmatches.com and snipershide.com and precisionrifleseries.com
go to one of those, contact the match director and ask if you can come help.
the weekend after that, he is hosting a "new shooter" match, which is the same course of fire, but less competitive and probably with bigger targets. you should sign up and shoot in that.
edited to add: i'm shooting in the match this coming weekend, though I don't expect to be very competitive as I have been shooting AR15s all winter and barely even looked at my precision rifle since the finale in december. (and some of the best shooters in the country will be there)
