.410 Bore Shotgun Choke Size Chart

.410 bore shotguns are the smallest shotgun gauge used for hunting and measure in at 2 ½ to 3 inches. The payload is also the smallest, with most loads weighing in at ½ ounce. Due to these factors, it’s important to keep the pattern together longer, and that means a tighter choke tube.

The modified choke tube, at 0.402”, is the best choke tube for the .410. It’s tight enough to be effective to 30 yards while still being open enough to hit close shots on fast moving birds.

If you want an affordable, versatile waterfowl choke tube – that can deliver tight patterns at longer ranges – look for a ported choke tube that costs around $80. It will work well with most .410 shotguns while hunting over decoys or for passing shots. (The Patternmaster Code Black has been our favorite for this style for many years). Check it out, you won’t be disappointed.

Yes, all 410 shotguns have chokes. Chokes are either fixed or part of an interchangeable choke system. Fixed choke 410 shotguns have the choke size fitted to the barrel itself which can’t be changed easily. 410 shotguns with choke systems installed allow you to unscrew and change choke tubes in seconds.

The diameter of a 410 shotgun with an improved cylinder choke is 0.409”. This is essentially the bore diameter of a 410 shotgun. The choke diameter of a 410 shotgun changes depending on the tightness of the choke.

A 410 shotgun with a full choke has a diameter of 0.398”. This is one of the tightest chokes tubes a 410 shotgun can have.

There are 6 pellets in a 00 buckshot load of 410. Winchester and Sellier & Bellot both manufacture 00 buckshot loads for the 410 shotgun. While 3 inch loads can hold 6 pellets, 2 ½ inch loads can only hold 5. See this chart for more on buckshot pellet sizes.
