Tru Lock Federal HW7s choke

[MDTOM84]

I got a Tru Lock Federal Heavyweight#7 choke for my Remington 11-87 20ga but it doesn't say what the constriction is on the choke or the package. Does anyone know what the constriction is on it? Thanks

According to their website if it's a Remchoke it's .560 exit diameter with a constriction of .060

Never mind, I got the TSS and Heavy weight stuff confused

If the constriction is 0.060, then the exit diameter is going to be .580, not .560...

My Tru Lock heavyweight 7 is a .560. I measured it with digital calipers.

Well then that means either the website is wrong or your calipers are off, because .640 minus .060 is .580...

I know that my Trulock Federal HWT 7 choke is .560. 
They also have a Trulock TKY .575 that shoots real nice w the Federal HWT 7 shot (that's the choke I'll be shooting this Spring).

From Trulock Website. 
If you look at the SKU you will see the last three digits are the size of the choke.
.560 for #7 TSS
.555 for #9 TSS

SKU   CONSTRICTION TYPE   CONSTRICTION
   
F7TREM20560   Federal #7 TSS   0.060          

F9TREM20555   Federal #9 TSS   0.065   

I was told by a guy at Trulock that the HWT 7 and the TSS 7 is the same exact choke.

No. Measured again with another set of calipers. .560. Website either wrong or your reading it wrong.

Smh.  It's very simple math.  I said if the website has it at .060 constriction and you're reading it at .560 then what's that tell you?...

Thanks guys, I'm going to try the Tru Lock as soon as it warms up some. I have been shooting a Carlson's .575 and I've been very happy with it but I'm more curious then anything about the Tru Lock. Thanks again for the info

Where did you get that a 20 gauge inside diameter is .640???

it tells me you would need a bore diameter of .620.  .620 + .060= .620. I dont have a remington 20 ga to measure but i have 2 mossbergs that i have measured one is .619 other is .617 so .560 is close

sorry my last post I typed it wrong it should have been .620- .060 = .560 or .560 + .060 = .620 . next time i'll read it before I post it

NOMINAL bore is around .615 and there are over bored 20 gauges,  though I got it from the OP's post since you're asking...
