I am an agreement with SouthernStrut. I have the Remington 870 SPS-T with thumbhole and I use a Primos Jelly head choke tube and I am getting nice patterns out to 50 yards with the Federal Flight control wads 3.5" #5 shot. The next best that I tried was the Winchester Supremes 3.5" #5 shot with same choke and gun. I tried the Hevi-shot Hevi 13's, but the patterning was absolutely aweful! I have read that the Hundertaker gets pretty nice patterns with the Hevi-shot, but I haven't tried the undertaker tube as of yet. I will probably do some experimenting with it after the season is over with. The 3.5" Federals with the jelly head is what I am going with for this season. Best of luck to you this upcoming season!
