40 yards lasered, shot a big sheet of paper and it shoots a hair low with this choke but the pattern is really good.

nothing wrong with that pattern
good luck this season
your ready
I shoot the same setup with the same results. I'm shooting a .655 tightwad and love it. The 390 is a sweet shooter. heavi-shot #6's shoot good too.
