Pistol length barrels do not make the most out of modern powders, 18"+ length barrels burn up all the powder.
I used only a 23in barrel for everything for a long time, only got a 28in barrel because I wanted to leave my turkey sights on the 23in barrel and preferred a bead to sights for waterfowl.
Yes, I have personal experience with short barrels and buckshot, dead deer too.
Fox the charts are all for 2 3/4 shells. But if you look at the difference between the 18.5, 21, 26 and the 36" barrels there is about a 100 FPS increase. A 100 FPS difference in a shotgun is not peanuts. Barrel length has an effect. The more powder there is to be burnt, or the slower the powders burn rate the more of an effect it will have
Can you find the same test done with 3" shells?
Your 23" barrel probably allows 95% of all powder loads to be 100% burnt and gives good velocity.
100fps over the 18-36in range, not for one inch.Quote:

The 3in load will have a tad more powder but not anything that will be significant really, when you look at 100fps you can have that much variation between shots or between barrels of identical lengths but different brands, it does not mean that a Remington barrel is better than a Winchester barrel due to the extra 100fps of the shot from the Remington (brands taken as examples, not testing).
The idea of the longer barrel and more range comes down to the old black powder days, the longer the barrel the more space to burn the old powders and the increased velocity, but this was only to a point.
You can be more accurate with a longer barrel if using open sights, you are simply lengthening the sight radius but accuracy and velocity are not the same, a short barrel (long enough to burn the powder) with a scope on it compared to a longer barrel with a scope on it will not lose anything for accuracy unless maybe the longer barrel makes it heavier for the shooter and they pull less.
The main reason for the 28in barrels is feel and point, I started out with a 30in barrel on a single shot, went to a 23in barrel on a pump, fastest gun to get on bunnies, now I like 30in barrels in a SxS 16, points great, short enough for the thick bush but never have I had any concerns about the speed loss by using that 23in barrel, it was my only gun and only barrel for it for a long time.
Fox, lets get back around to the reason I was pointing out barrel length.
Looking at Velocity not as cause and effect, but as a symptom.
Let me lay it out.
3" shell with heavy load using a slow powder.
Short barrel causes a lower velocity because of incomplete powder burn.
Wad cup crosses the transonic barrier before it fully opens.
Wad cup begins to tumble, and the shot load is scattered.
Ok, so 100fps between a 36in barrel and an 18in barrel, so 5.56fps per inch. Between a 28in barrel and the OPs 21in barrel is 38.9fps, does that have a great impact? Even with a 3in shell?Quote:

Now, when you are talking about slow burning powder, Universal rates as #33, HS-6 as #43 from the Hodgdon burn rate chart, 1 being the fastest. 4198 is a fast burning rifle powder, this shows up as #73, shotgun powder is really fast burning powder, adding a few inches of barrel or even moving to a "slow" burning shotgun powder you are still talking about a very fast burning powder in a relatively long barrel.
Fox, you can post powder burn rates till your keyboard melts, it does nothing to answer the question of " does the wad destabilizes before it fully opens".
Shoot the ammo and find out, what about the managed recoil loads? 1200fps at the muzzle vs 1325 fps for 2 3/4" standard load vs 1225fps for 3" standard load, are they using different wads in all loads? Their tactical loads that they market for short barreled tactical shotguns are 1200fps and 1325fps, are these also different wads?Quote:

It is the same as asking, will Remington Core-Lokt loads shoot well in my gun.
Nice blanket thing that has no answer.
You have to shoot your gun, the OP shot one load that he did not define and people started saying it was his barrel length, bologna, it is his gun/choke/ammo combo not producing the pattern that he wanted, stop blaming the barrel length, there are lots of other components and lots of other factors that have a much higher impact on the pattern.
Fox, tighter extended chokes was one of the first things I listed to try. Along with tighter chokes a longer barrel.
