Trulock Fed #7 choke question

[decoykrvr]

Unlike most of their other choke tubes, Trulock does not list the internal diameter/constriction of this choke for a Winchester/Winchoke-Browning Invector.  Any information on this or the internal design?

I was wondering the same thing.

Call and ask them.

When asked about he specifics of the choke tube (and I don't really blame them) the folks at Trulock pulled an Earnest T. Bass, "You might ask, but I ain't talkin.  The more you ask, the more I'm balkin."

Yeah, on their web site when you go to Fed #7 choke and look under constriction in 12 or 20 gauge from A-Z brand gun it shows choke diameter  as .000.

If it truly is all about internal geometry and not so much exit diameter then why be so secretive?
Also they have an exclusive fee of $55 or so for that .000 . I have not seen any complaints about his specialized chokes for the Fed HW #7 but to be honest I haven't seen much of anything on these.

I called Trulock the other day and asked about that choke.  For a 12 ga. Winchoke the constriction is .650 and for a 20 ga. Remchoke the constriction is .565.
