Frequently Asked Questions

How does a Poly Choke adjust on a shotgun?

A Poly Choke is adjusted by twisting the choke tube at the end of the barrel. Markings on the choke typically indicate settings like Improved Cylinder, Modified, and Full, allowing the shooter to select the desired constriction for different shooting distances and patterns.

What is the difference between Improved Cylinder and Full Choke?

Improved Cylinder is a more open choke, producing a wider shot pattern suitable for closer ranges. Full Choke is a tighter constriction, concentrating shot into a denser pattern for longer distances, which can increase the effective range of a shotgun.

Does a Poly Choke affect shotgun patterns?

Yes, a Poly Choke significantly affects shotgun patterns. By adjusting the choke constriction, you can control the spread of shot. Tighter chokes like Full result in denser patterns at longer ranges, while open chokes like Improved Cylinder spread the shot more for closer targets.

What kind of shotgun is featured in the video?

The video features a vintage Mossberg 185K-8, a 20 gauge bolt-action shotgun. It is noted for having a removable box magazine, which was somewhat uncommon for its era.
