i have a benelli Vinci and i was wondering if i should use a full that comes with it or a double full choke for turkey hunting

How do they both pattern?

I'll second that... Most likely the extra full turkey choke going to get it done...

What you have should be fine but you will almost certainly get better patterns with a tighter choke as distance increases.Weather or not you need it only you can decide.

i know the regular choke will be fine but i was wondering if yall would perfure a extra full

As you heard, most people prefer whichever choke holds the tightest group at the furthest distance with no gaps in the pattern.

Only one way to know that; gotta shoot them at a patterning board at various distances.
