This chart shows the popular Browning choke tube diameters from 20 gauge all the way up to 10 gauge. Common choke tube constrictions are listed for open bore to a more restrictive turkey choke.
Browning Invector and Invector Plus are the two most common types of Browning choke systems. Bore is the diameter of the shotgun bore without a choke installed. Cylinder is the least restrictive choke diameter for Browning shotguns.
Full, Extra-full, and Turkey chokes are the tightest diameter Browning choke tubes with the most constriction. These types of chokes deliver tight patterns at long ranges with maximum pellet density.
Browning 20 gauge Invector chokes have a smaller diameter compared to 12 gauge chokes due to a smaller barrel. Additionally, 10 gauge standard chokes have the largest diameters due to the increased barrel size.
