Invector choke tube

[KPcalls]

Do any of you guy's know what size this tube would be...? I've searched all over and can't find a size on it. It came with a BPS I bought 8-10 years ago.

Mine measures between .685 and .690

That's the one I shoot with TSS in my Brownings.

Thank you shooter...With the finger test I can tell it's more open than my jellyhead....

That's the one I shoot with TSS in my Brownings.

That's what I wanted hear..... Waddle Whacker is schooling me on loading some TSS 12 gauge 2 oz. loads this week. I've got the choke pictured an older jellyhead and a flush full...so, hopefully I will be good to go on one of the three.

Sounds like that might be the one!

Mine measures .698 so .044 points of constriction on that Invector+ bore of .742.
