I bought a Higgins Choke Master. It is a perforated noisemaker tube with an adjustable choke (like a Poly Choke) on the end. I've never seen one like it.
It has six detent settings. They are listed below with each measured inner diameter.
Cylinder and Slug- .751"
Improved Cylinder- .748"
Modified- .744"
Improved Modified- .740"
Full- .737"
Extra Full- .733"
If 12 gauge barrels are nominally .730" then how could this choke be doing anything. It doesn't look extremely worn.
Could the inside of the collar be worn away enough to make this much difference
Does the shot spread out in the compensator tube and the diameters of the chokes are adjusted for that?
Is it likely that the diameters are correct?
