If your shotgun accepts chokes any budget ammo that cycles your gun will be fine for a local match.
Added emphasis is mine. Brand new gun, do not buy 250 until you know.
Will 2.7 DE/1145 fps work? Maybe not, depends on the matches. If they like to put poppers out a ways then, no. To get started, pay the extra $15/case and get birdshot with a little more oomph. I run #7.5 1255fps 1 1/8 oz to be sure, and when I shoot a popper, it goes down.
No need to get more oomph than that.
