I don't know if you are aware of this, but we have a growing .22lr semi-auto match at Nicks Shooting Range in Garyville. I have been shooting the Bolt class for a while there, and just got into the semi-auto class.
Its a lot of fun and some nice folks shooting there. The matches cost 22 dollars, which includes targets and ammo (as we all have to shoot the same lot number of Wolf)
Every participant in the semi-auto is (as of last weekend) is shooting a 10/22, modified to some degree. some are shooting with bipods, some with sand bags and some shooting on rests. The only rule on rests are no one piece rest.
If you need more info you can call me on my cell 225 206-7023. My name is Roy Zeringue
