Yes it’s fine for turkey hunting. Just like OTC medicine is directed as taking so many pills, you could actually take half a bottle if so desired, lol.
Now if you’re on hog patrol with the USDA shooting thousands of rounds a year, the choke is the least of your concern. You’ll be replacing that barrel once a year. I’ve shot Hevi13’s and TSS for years through a Kicks GT with no ill effects. I shoot a custom choke now that will shoot anything I want to throw down the barrel.

Interesting. I will say that I fired the TSS (and some other stuff - Winchester longbeard, Federal lead turkey #5 shot, etc.) through the factory x-full choke and it all patterned terribly. Like, nothing patterned well. Gun is a Mossberg 935 if that matters.

I have fired some lead shot through this choke and it does seem to be a big improvement but honestly it was not optimal setup for patterning the gun so I will probably try to do a better experiment with the lead shot this weekend.

Here we go again!!
Sorry jbyrd63 but Tungsten or Wolfram atomic symbol W is NOT STEEL. It is a very rare ELEMENT #74 on the periodic table of elements. It IS a metal that is about five times harder than steel and about the same weight as gold. Steel is an alloy of iron which is another element, atomic symbol Fe and other metallic elements such as chrome, nickel, molybdenum ect.

Pertaining to the OP. Large steel shot acts like RipRap as it moves very little if at all when you walk on it whereas
small steel shot tends to flow like sand. This is the reason size restrictions are put in. ie no steel larger than #4
Both Steel and Tungsten will score and damage a steel bbl if they come in contact with it. The “bridging “ effect of large steel shot mentioned earlier has a double whammy as it’s more likely to “pinhole” the petals of the wad, allowing the shot to come into contact with the bbl, and to bulge the choke due to the shot charge’s resistance to flow through the restrictions of the choke.
Will the TSS turkey loads damage a extra full turkey tube?
Due to the small shot size of most TSS loads I seen advertised 7,8,9, and the super heavy duty wads used
by the manufacturer probably not ( flow and resistance to “pinhole”). It will be interesting to hear the choke mfg
answer. Hope this helps a little.

I can tell you what the manufacturer will say...No. Why say that his choke will work when they can sell him another choke that “is” approved, lol.
Someone above mentioned patterns with a choke. I shoot 3” 1 5/8oz of #8.5’ and 9’s out of my turkey gun and get a nice even no holes pattern at 40. Now if I shoot that exact shell with only 1 3/8oz shot, it doesn’t perform as well. My particular choke just likes the larger payload for some reason.
They are coming out with a 1.75oz load of #9’s that I’ll probably shoot to see what they do.

Slydogx Anything back from Tru-Glo yet?
Curious what they’ll say.

Nothing yet

Federal just responded and suggested contacting Truglo for "a definitive answer" LOL
Still waiting on word from Truglo

Thanks, keep us posted ? I’m inclined to agree with Wanna Be. Tube mfg no. Shell mfg Shur no problem.
I do know that the waterfowl steel specific extended tubes are made of some really tough stuff 17-4? if I remember correctly. They also have a very gradual taper to the restriction. And shot size and even velocity disclaimers.

Truglo will never say its okay because it was never tested and TSS wasn’t considered when the choke was designed. Its just a liability thing. Theres no reason it shouldn’t work, but if you’re nervous buy a new one.

With the liability laws in this country you can bet if it was a danger to shoot turkey loads through a turkey tube you can bet warnings would be all over the boxes/tubes. LOL

That ankle deep kiddie pool with the no diving sticker comes to mind here.

Good analogy

Well, no answer from Truglo so I'm going to assume I won't get a response anytime soon. If I do hear from them, I 'll update the thread

Well, no response from Truglo but this is settled for me. I ran 1 round of Federal 3rd degree TSS through and no damage or scoring was evident...but
All pics at 20 yds, in order
Federal 3" #5 turkey shot
Winchester Supreme 3" #5 turkey shot
Federal TSS - still a dead bird, but no sense in spending the extra money in this gun

If those pics are in order then I won’t ever spend money on Federal TSS.
And don’t take this wrong, but at 20yds that looks like a Modified choke. With a turkey choke you should almost be blowing the center of POA out. That first pic should be what your 40yd shot looks like.

Federal #5 loads are my choice looks to be the best that last target has a big miss spot in that pattern.

Kent 3 1/2 2 1/4 #5 diamond shot at 41 yards (41 yds so I could sit on the porch).

From the TSS I have shot in 12 and 20 gage, TSS does not like the constriction of your typical extra tight turkey chokes. I shoot hand rolled TSS in my 20 through a factory full choke and it has a better pattern at 40 yds than any posted on this thread. My standard for patterning TSS is 40 yds and I get over 200 pellets in a 10" circle with my 20 at 40 yds.

Very nice pattern...and I like your thinking (41), lol!

I'm going to keep trying until I get something the gun likes, but I have a limited amount of time to get out and do things like patterning guns. I may even invest in another gun for turkey and keep the Mossberg as a goose killer.
Results through the factory x full choke and the Truglo choke have not been really satisfactory

Them 1st and 2nd targets look doable to me.

OK looks like your wasting your precious time if you want something better than the first pic!! LOL. Just how dead you want the bird. ??? TSS IS NOT the end all some claim. Been MILLIONS of birds killed with lead and they are still dead !!!
