I've read mixed reviews of Federal's mag-shok turkey load with the Flitecontrol Wad and an xtra full (turkey) choke. I picked up a box on sale for my son to use with his 20 ga, #4's were all they had for sale. I haven't had a chance to pattern this load yet. Does anyone have any experience with these Fed loads (esp 20ga) and choke recommendations with them? Thanks
