What differences does it make in a pistol or revolver? Back in the 70s or so, Dan Wesson brought out its interchangeable-barrel Magnum revolver , which could be fitted with barrels of various length, from 2 to about 14 inches if I recall.
A report came out examining various issues of shooting performance in that revolver as the barrels were switched from the shortest to the longest.
There was very little demonstrated differences in the bullet velocity from one barrel to the next, but there was some. Just not as noticeable as in a centerfire rifle. Other differences were noted though. The short barrels are more portable and indeed concealable. With full-bore loads the muzzle flip or recoil can be considerable as can be the muzzle flash and muzzle report. Of the guns in attendance, only one has the option of changing chokes, so the main focus of the discussion centered on barrel length.
First, a little bit about the differences between long- and short-barrel shotguns. An example of this length is the Stoeger M3K. Longer barrel lengths are used to maintain a tighter column of shot for a longer time period and it also tends to give a bit higher velocity to the shot leaving the barrel. This helps the shot to settle and have fewer pellets sling themselves laterally when they exit the barrel.
The column tends to remain tighter further out, which is a decided advantage with longer shots found in 3-Gun, trap, skeet, upland bird or even deer hunting. With more of the payload remaining in the center of the cloud at a given distance, the likelihood of a successful engagement increases. They are heavier and much slower-pointing. This is less of an issue in trap and perhaps 3-Gun, as the targets are predictable. In dove hunting, where the birds just appear and fly wherever they want, a lighter handier gun is easier to use and probably a better choice.
The KSG is a fairly unique shotgun. There are few factory bullpup options and having a twin magazine tube is unique, as far as I know. For the initial test, we only shot size 7. I loaded one tube with that and left the other loaded with my home defense Federal flight control 4 buck. Should the zombie apocalypse have kicked off during our birdshot demo, a quick flip of a lever would have given us seven rounds of much harder-hitting shells.
When I showed her that option, it made her giggle. The sign of a woman well on the way to becoming a gunnie convert. Kel-Tec chose to use an On the standard version, the overall length is On a shotgun with an Hopefully, those dimensions point out how handy the gun is. Getting through a doorway with the firearm at the ready is quite simple. The other reason is that I can have a tube of The Federal flight control 4 buck in one tube and the other filled with Brenneke Classic slugs.
Couple those with my red dot on the top rail and rapid shots out to yards group at three inches. The Remington and Mossberg A as I own them are very similar firearms. This is a fairly inexpensive upgrade. Mine has slugger sights, but other than that, it is a fairly run-of-the-mill Express. The agency retires all guns at the seven-year mark, so I got a slightly used seven-year-old gun. I got a great gun that had been broken in, but not broken.
It also sports an The magazine is not easily upgraded, unless you want to do a conversion to make it work with detachable magazines. The thing I like most about it, other than its heavy construction, is the safety across the spine of the action. This is much more ergonomic rifle-like for me than the cross-bolt safety of the and Kel-Tec. All three of these guns have This is a large disadvantage past 20 yards with birdshot and 30 yards with buckshot.
When hunting doves, I find that my percentages typically go up on hard-flying birds in proportion to barrel length. For dense cover and snap shooting, portability outweighs balance. Rifle and pistol shooters are affected by the length of sight radius, and that term has bled over into discussions regarding shotgun barrel length.
Velocity is more easily analyzed than balance and swing since it can be measured with a chronograph. So the difference between a inch and a inch barrel will be 60 feet per second with light target loads—hardly a significant difference. But I wanted to test these theoretical values, so I rounded up and gauge guns with barrel lengths measuring from 24 to 28 inches. Velocities were measured with the muzzle 12 inches from the chronograph, and the results are shown in the accompanying chart.
Barrel length may not have a major impact on shotgun muzzle velocity, but it does affect handling. I spent a miserable afternoon in Maine chasing grouse with a side-by-side gauge sporting inch barrels. The gun was worse than useless in that jungle of alders, and when I eventually switched to a Browning BPS Upland with a inch barrel I fared far better.
On the opposite end of the spectrum you have target guns designed for clay games.
