This question is to the shotgun experts here. What is the optimum barrel length for a SD/HD shotgun?

28-05-2009, 01:59 AM
I am not expert but i say 20 inch

18" to 20" inch is most popular but if you can handle & swing easily any lenghth can be deployed for the role.

@CC bro minimum of 18 inches of barrel is required for complete burn out... therefore any length above 18 is best .... otherwise you have shotgun pistols which are of 6 to 10 inches...

For hunters! The best rule of thumb is to select the longest barrel available for the type of HUNTING done most often. Most misses are caused by stopping the barrel’s swing to and through the target as the shot is fired. Longer barrels assist in smooth swing follow-through, and also provide the increased sighting plane needed for longer shots. Remember that with the advent of choke tubes, almost any length barrel can have almost any degree of choke. Big game hunters who use slugs now have the best of both worlds. The traditional Foster-type rifled slug, a weight-forward lead projectile with a hollow base and side vanes, has been greatly improved. And the relatively new sabot slugs, when fired from a fully rifled barrel, can result in awesome accuracy at incredible distances.
OTHERWISE! If one has to compare the pros and cons of longer barrel Vs Shorter Barrels then;

Longer Barrels

Pros: Longer sighting plane, less noise, less muzzle flash, less recoil.
Cons: Harder to maneuver with, heavier weight.
Longer shotgun barrels are generally best suited to hunting and other sporting purposes, such as trap, skeet, and sporting clays. These longer barrels provide a longer sighting plane, which makes it easier to accurately aim the gun. This is because the sights are further apart along the length of the barrel, and it is more apparent when the sights are correctly or incorrectly aligned on the target, compared to a shorter barrel. Longer barrels also produce less noise and muzzle flash. This is because the pressure inside the barrel has dropped to lower levels by the time the projectile(s) exit the barrel. There is also less recoil on a gun with a longer barrel, since the added weight of the barrel reduces recoil. Some people will claim that longer barrels will result in increased muzzle velocity, but this is generally not the case. An 18? barrel is sufficiently long to allow the gun powder to burn and accelerate the projectile(s) to their top speed, and for the pressure to drop to the point that using a longer barrel doesn’t add velocity to the projectile. In fact, when shooting sabot slugs from a rifled barrel, excessive barrel length (perhaps beyond 30?) could result in additional friction between the projectile and the barrel, reducing muzzle velocity. The cons of a longer barrel are reduced maneuverability, and added weight. The reduced maneuverability is a prime concern for home defense shotguns, which is why I recommend an 18? barrel for home defense shotguns. A 30? barrel would be harder to swing around in close quarters, and would be easier for a home invader to grab the end of

Shorter Barrels
Pros: More maneuverable, less weight
Cons: Shorter sighting plane, more noise, more muzzle flash, more recoil
Shorter shotgun barrels are best suited to home defense shotguns. The shorter length allows the user to maneuver the shotgun more freely. I recommend an 18? barrel, which will allow the shotgun to be swung with ease, but will still maintain the full ballistic performance one would expect from a longer barrel. The cons of shorter barrels are the increases in noise, flash, and recoil. As the projectile exits a shorter shotgun barrel, the (relatively) high pressure gases are released, causing more noise than there would be with a longer barrel. This extra noise can be a nuisance to neighbors, or be seen as a violation of etiquette when trapshooting. Similarly, there is an increase in the muzzle flash, which can also affect the night vision of the shooter or those nearby. Shorter barrels generally weigh less, which means the shotgun will recoil a bit harder than it would with a longer barrel. For these reasons, a longer barrel is generally better for sporting purposes.

Pick the shotgun barrel length that is appropriate for whichever shotgun activity you have in mind. Changing a shotgun barrel is no harder than cleaning the shotgun, and can be done by the user with no tools required. I encourage everyone to buy multiple barrels for their shotgun, and enjoy the use of the proper barrel for each shotgunning discipline.

Good show talal bhai.... it means you can write articles for websites and mags.... (if u delete "Courtesy learnaboutgun.com

thanks for the info everyone.

barrel length down to 14inch is fine, a little short for my taste but still ok for the job. however those 10inch or shorter barrels are for hollywood only.


28-05-2009, 08:55 PM
yea, 18-20".

12 gauge the 14" will not give more jerk ?

29-05-2009, 04:39 PM
yes it will, compared to, say, an 18" or 20" barrel, just like talal bhaee has said in his excellent post. so i think 18"-20" is considered a good balance between the reduced size and increased recoil etc., just like ahmed bhaee pointed out.

29-05-2009, 04:43 PM
usually people like long barrels, but there are some who like short length.

Yes it does but jerk/kick/recoil isnt that important, the muzzle flash and sound is absolutely horrible.

Hmm mine is something 18 or so.. would putting a muzzle break help?

29-05-2009, 11:35 PM
not actually, muzzle breaks on shotguns in my experience are not very effective, however it will reduce muzzle flash. but then again, 18 inch is a good size anyways, so you are pretty much covered my friend. (strictly speaking of barrel lengths ofcourse :lol:)
