Browning Gold- Which choke for lead?

[TheSportsman]

What choke would you lead shooters recommend for a Browning Gold NWTF 24" 12ga 3.5"?  My favorite lead load is Winchester High Velocities 3.5" 2oz number 5s.  What constriction would you recommend?  Ive got a Pure Gold .670 and a Jellyhead .670, but ive never shot lead through this gun.  Would that be about the right choke or would i need something tighter? thanks

I like 675 to 680.  Now others have good luck with the 665 and 670. 

I like the Fed FCW with that gun.

I would start with 3 shots through both of the chokes you already have and see where you are with them. No need to buy more if those will work. I bet the PG will shine.
