Thanks Jesse, and welcome to NES. I ended up using the 28" barrel for that match and it worked fine. The plan is to get a semi-auto shotgun before next season. I have high hopes for the Mossberg 930 competition model that Benny Hill and Jerry Miculek are working on. Hopefully it'll be ready to be shown at SHOT.
After I posted that I realized there were 10 pages to the thread. I didn't get to read them all yet but i figured my response was useless at this point.
