Default Factory full choke diameter for 20 gauge topper?

Maybe I missed it somewhere in the sticky but I've searched a while without finding the answer. On the other side of deer season, I plan on making a dedicated "run & gun" turkey gun out of my topper 20 gauge. I have two barrels. A factory full choke and a modified. Anyone know the diameter for the factory full? I may just get one of them tapped for removable chokes to get to an "extra full"

I have heard and read on this site that people are succesful with both. Very limited with mod choke distance wise. Plenty a gobbler has been killed to the factory full choke. I have a table somewhere for diameters. 20 ga turkey loads now are better than ever. I would suggest picking up some and do the 10 in circle test at 30 and 40 yds. Count the pellets in the circle and be sure your pattern is straight. I have just had a gunsmith cut a factory modified down and thread for chokes. Its 20in and Dinny sent his at same time and duplicate work and he has field tested his with awesome results. Its worth it. But your factory choke could be wonderful already. Just watch cost because you can wind up investing as much as you could pick up a pump short barrel factory threaded gun for. My case i bought a complete shotgun for 60 bucks to do my work on. So im good.

Just put a micrometer on mine & read 0.602 inside diameter, 0.740 outside at the muzzle.
