FAQs

What do the notches on yildiz chokes mean? ›

To generalise, the tighter chokes, marked with 1 or 2 notches (known as Full and Three-Quarters) are for the longer range shots as they hold the shot pattern together over a greater distance. These are also used on the larger quarry species such as geese or foxes.

What do the notches on the choke tubes mean? The notches indicate the choke tube constriction. A lower notch count means more constriction (tighter). A higher notch count means less constriction. 1 notch = Full.

* Many popular turkey guns come with chokes with a . 665 constriction, which shoots No. 5 or 6 lead shot extremely tight.

Choke tubes come in four standard sizes. These are commonly known as Cylinder Choke (C), Improved Cylinder Choke (IC), Modified Choke (M), and Full Choke (F). When screwed into the end of the barrel, choke tubes reduce the bore size of the barrel.

The Americans came up with their own system, with the designations: full, improved modified, modified, improved cylinder and cylinder. The Europeans, just to be different, have a system of using asterisks or punch marks, starting with * for full choke, ** for ¾, *** for ½, **** for ¼ and CL for cylinder.

For shooting slugs, experts often recommend using a cylinder choke or an improved cylinder choke. The reason behind this is that slugs can safely pass through these wider chokes without the risk of damaging the gun or affecting the slug's trajectory.

Is Turkey choke tighter than full choke? ›

A turkey choke typically provides more constriction than a full choke and can produce the tightest patterns of shot. This can aid in effectively targeting a gobbler's vital areas, which can be particularly challenging when turkeys are in motion or strutting.

Four notches often represent a improved cylinder choke, perhaps the most versatile of choke patterns.

Full Choke Shotgun

This choke is the most closed. Full choke produces a tight pattern of distribution of the shot. Commonly used when hunting turkey. Full choke is commonly used for longer range.

Full choke has tight constriction. The shot holds together even longer, making this choke good for squirrels, turkey, and other game shot at 40-yard and longer ranges. Turkey hunters sometimes use Extra Full or Turkey choke for even denser patterns at long range.

Full Choke Shotgun

This choke is the most closed. Full choke produces a tight pattern of distribution of the shot. Commonly used when hunting turkey. Full choke is commonly used for longer range.

Barrels that use the Mobilchoke will typically be marked only with the gauge marking. Mobilchoke choke tubes will be marked PB or ST and the degree of choke. If the choke tube is steel shot compatible it will also be marked SP .
