20g choke restriction..

My factory choke is a .584. going to shoot tss 9s. Haven't patterned it yet with the tss. Just curious what chokes others are using.  If this has a decent pattern at 40, I might not mess around with it.

I bagged my first turkey with a 20 gauge last year on opening day. I used tungsten 9's with an Indian Creek .555 choke tube. The shot was at 35 yards and it dropped the bird dead right there. It was such a a pleasure carrying a lightweight 20 gauge after many years of lugging around my 12 gauge. If you get a good pattern with your factory choke those tungsten 9's will do the job.

Late to the party, Most 20 ga chokes in the 555-570 range will shoot the best patterns. But there is some Loads, with certain wads that like the .575-.580" range. I wish with manufactured loads, they would tell you what wad is used. Certain chokes like certain wads, and certain choke exit diameters, like certain wads as well. I have messed with the 20ga 28ga and 410 world for many years now. ITs became a hobby lol

Hopefully I'll get it patterned today.  Lack of turkey sighting and work coming in faster than I can pump it out, doesn't have me very excited about this season.

@mowin what Bryan said here holds true. If you're using Federal tss ammo they're likely stuffed with their flightcontrol wad. those suckers are stiff as hell and like a more open constriction. otherwise the pattern has holes and appears blown. when i tested my 12ga with them its what I found. I'm thinking the a tighter constriction gets hung up harder coming out of the choke and causes the wad to be unstable. that wad is otherwise supposed to stay with the shot longer and pull away clean with drag versus being stripped from the shot quickly by the choke porting.

The biggest thing with TSS, is getting the wad off and away from the shot as fast as possible. So you chokes with wad strippers, or ports will typically  yield better patterns in terms of TSS, probably lead as well.

that was the problem with the first flight control wads like 10 years ago that I tested quite a bit. didn't like porting and wad stripping chokes. new ones are supposed to be better and not designed to stay with the shot way longer than normal. still say it's safer to go with a more open constriction so the heavy wad isn't getting all malformed and effecting the shot column. open constriction turkey choke with a long length/transition and elongated porting is what i'd go for.

So, that was disappointing.  Used field loads at 10y to get the red dot adjusted.  Shot a federal tss at 20 and wasn't impressed at all.  Made up a 40" sq white paper target, and shot at 30.  Patten was horrible. 

No time to mess with it this year.  Next year I'll get a couple different chokes and mess around with it.  I'll carry the 12g.

When you have free time try and find a .560 diameter choke, I dont know federal too well, but i do believe they like tight chokes. But Federal is also one of the least performing shells on the market. If you're looking for custom tss to your door step. PM me. Can point you in the right direction. To a load that shoots well from a 20ga i have that choke mics to .583" and is a 60yrd gun

choke tube combos are so finicky. lol .584 is pretty open though from what i've seen looking for a choke for my mossberg 500 20ga. i quit looking because i spent so much testing stuff out for my 12ga. that was before TSS blew the roof off the cost of ammo.

My little bantam 500 20 ga with a certain wad will shoot phenomenal with a cheap .575 undertaker. And shoot phenomenal with a different wad with a .555 Indian creek 

Definitely can spend some money if your trying to maximize.

Well, I realized I kinda messed up.  When I asked the guy at the counter for 20g tss, he gave me 2 3/4" 9s.  I stupidly didn't check, and thought they were 3".  So I went back today and bought a box of #6 Winchester XL 3" and a box of Remington 3" tss 9s.  

The XL wasn't bad out to about 25 yards, then it opened up a lot.  The Remington 9s did well enough at 35y for me to hunt with, and I'm sure a tighter choke will tighten up the pattern some.  Ran out of turkey targets, but this worked. 

The black tape is about 1x2" and had 10 pellets in it. I'll limit my shots to 30y, and I should be good.  Patter loos to be a tad high, but I really don't want tss pellets in the breast meat.
