TSS choke question

[blackforesthp]

I am going to try shooting some TSS #9 this season in a 20 ga 870.  I had great results with the gun last season using Win. LongbeadXR #6 and the Carlson LongbeadXR .568 choke tube.

Do any of you who use the 20 ga 870, ever shoot TSS our of a .568 choke.  I know Carlson's make a .555 TSS choke, but is the .013" difference in constriction going to make a noticeable difference over my current choke.

I seems like just switching to TSS is going to be a huge improvement over the LongbeardXR I shot last season.  The Longbeard was a big jump from the lead 5's I had used for years before that. 

Normally I like to call them in close or I don't shoot, but this year I have trips planned to hunt 3 of the four species in the grand slam, so I would hate to be on a hunt where I needed an extra 10 yds range and not have it.  I figure it's cheaper to get a better choke/shell combo than the expense of a hunt away from home.

Thanks in advance

Around .570 is a good place to start with TSS in the 870.  I'd pattern your .568 before buying another choke.

As soon as my TSS arrives I will do just that.

Thanks for the reply.

A lot of people use the Carlson 575 with the TSS with the Remington 870...

My 870 youth with the .568 carlson longbeard choke and federal tss 9's averages 280-300 hits in the 10 @40. It also shoots several other rounds very well.

I would try it and see. As said above, I am shooting a 575 Carlson's with hand loaded #9. My son's gun shot a Primos Tightwad 570 better than the Carlson's for TSS.

Agreed!  .568 is very likely to throw some great hunting patterns!
