I need help from those with a micrometer.
I need to know the outside diameter of Rossi shotgun barrels at 18.5''.
I am looking at the single shots.
please list the model with the diameter.

Are you missing the micrometer or the shotgun? If you're interested in a high tolerance measurement, be advised they will vary from gun to gun. If you just need a fairly accurate measure consider the wire method. Take four or five tight turns of wire around the area you want to measure, mark across the wire, unwind the wire, measure the distance from end mark to end mark, divide by the number of turns, divide by 3.1416 and you'll have the diameter.

I am missing the shotgun.
What I want to do is cut a barrel to 18.5'' and thread a screw-in choke.
I want Rem-choke but it takes .83 outer diameter.
Hey zippy that wire trick is as easy as PI. lol..... I love puns.
