Here’s a quick guide so you know what those choke and choke tube names mean in the gun shop.
It should be noted that a traditional 12-gauge barrel has an inside diameter of 0.73”. Chokes are determined or categorized by (1) the deviation or constriction measured in inches from 0.73” and/or the number of shot pellets falling within a 30” circle at 40 yards measured as a percentage of the total pellets in the particular shot charge, e.g. 100 inside/200 total count or 50 percent.
The most common chokes and their uses include –
|Choke Name||Constriction||Percentage @ 40 yards||Uses|
|Cylinder or Cylinder Bore||0.00″||30-35%||Home defense shotguns; Foster-style slugs|
|Improved||0.10″||40-45%||Home defense; upland birds in heavy cover; trap/skeet; waterfowl over decoys with steel|
|Modified||0.20″||50-55%||All-around choice; trap/skeet; waterfowl with steel non-toxics; upland birds in all types of cover|
|Full||0.35″||70-75%||Late season upland birds, e.g. pheasants and prairie grouse; turkeys with high-tech ammunition, e.g. Winchester’s Long Beard XR; buckshot for deer; pass-shooting waterfowl|
|Extra Full||0.40″||75% +||Turkeys with lead or softer non-toxics; not advised for steel shot|
