RE: undertaker choke tube
I patterned with on in my Mossberg 500 a couple of weeks ago, between it and the Federal Premium Flight Conrol Wad 3" #5, I was getting patterns almost completely within a 20" circle at 35 yards. My experience with it, and everything 'Hunter's Specialty' makes has been rather well. I'd certainly give it a try. I guess it could be too tight at close distances with certain loads (like the one forementioned). I also got pretty good patterns with a winchester Supreme load that were not quite so tight.
