Another choke question for browning bps.

[johncornell]

Does anyone know what the constriction is on the Star Dot extra full (fake or real) being offered on ebay? I'm going to purchase an XF choke and also considering a Carlson flush mount constriction .700.  I don't want anything tighter than .690.

I don't know, but I'd guess it's probably tighter than .690.
