Test the load you're going to use. I know choke tubes are not exactly cheap, but see if there's other turkey nuts that have tubes that will fit your gun and try them.

Most brands have their fans & detractors. That being said, I used Win xfull and then went with a CompNChoke. I got a Briley choke tube, made for hevi-shot. It might not be worth the $ I spent, but we'll see.

Main thing is to get an idea of how your gun , choke tube and turkey load combination work together. Do this and your odds of making a good, clean shot increase. Whatever tube you go with, screw it in and clean out barrel, esp the tube with a bore brush. Even a new tube that looks clean will shoot better after cleaning.
