How important is barrel length?
Here I mean in terms of accuracy.
As I understand it a long barrel will do two things for accuracy: Longer sight radius if shooting irons, and less bullet drop for a given load due to higher exit velocity. So assuming the shooter can compensate for the latter, would a scope 4" (for example),not be just as accurate as a scoped 7.5" over a feasible revolver range ( eg 50-100m max)? It seems to me that if the scope is providing a reliable aiming method, rather than the sight radius, then a shorter barrel could be just as accurate, assuming that it is not at a distance where its lower velocity projectile is dropping too fast. Is this assumption/rationale correct?

All things being equal (and they never are), a reasonably short (i.e. long enough for rifling to stabilize the bullet) barrel will usually be more intrinsically accurate, because- in a nutshell- it will vibrate less on shooting. Longer sight radius and more recoil dampening are the main reasons longer barrels tend to offer more practical accuracy.

Once the bullet is stabilized, it's good.
Read up on elmer keith, he made quite a bit of shooting large bore revolvers with 3" and 4" barrels at 200+ yards accurately. |

Yeah, personally, I've never seen enough difference in barrel lengths to matter much, if at all, sights or scope.
The 4-5 inch barrel always seemed about right, revolver or auto.

As all have stated, accuracy is not dependent on barrel length once the projectile is spun enough to stabilize.
Longer barrels just give more velocity, up to a certain point, with most cartridges.

One factor to consider for the "big boomers" is that the longer the barrel the less muzzle blast you'll notice. Muzzle blast (due to the flinching you can get from it) can affect accuracy.

I've done a good amount of long range shooting with the handgun, out to 200 meters, even greater just plinkin'. My 7 1/2" Ruger Super Blackhawk has always been outstanding when great range is concerned. Once had a 8 3/8" full lug Model 29 that shot as well as a .30-30 rifle out to around 150 yards.
I've tried long range shooting with both 4 5/8" and 5 1/2" barrels and could never do as well. As to scopes, if I have to use a scope, I'll go with a rifle. These super power scoped handguns take the "handgun" out of the picture as far as I'm concerned. Now if that's your pursuit, fine, but like blackpowder, archery, and golf, just not my realm of interest. Bob Wright

So Bob,I take it you wouldn't want to give my Remington XP100R in .260 a spin.

I can only tell you from experience as I believe the barrel length is all about personal preference. I can shoot my 8 3/8" M57 much more accurately than my 4" M57. Both are iron sighted.
As far as scopes go on handguns, I believe that is also a matter of personal preference. I have a SRH in 480 Ruger with a 2x Leupold scope on it that I use for hunting. The scope makes shooting slower unless it is snap shooting. But it does give you one sight plane which for older eyes may be important. The scope gives me more confidence in my sighting out past 50 yds with that revolver. Red Dots and similar have really taken over the assisted sighting area with handguns depending on distance. Again it's personal preference. But under 100 yds, I would choose a red dot now over a scope for the most part. |

Very interesting, folks!
I am a little, yet pleasantly, surprised! I have never seen a shorter barreled revolver scoped and so I assumed it was because a shorter revolver could not provide the inherent accuracy that a scope could exploit. Based on comments here, that is not the case and if I can manage to get a scope mount for my Redhawk, I might be able to shoot further away, such as 100m. Cool!!

I also do my best longer-range shooting with my 7.5" barrel Ruger Blackhawk.

Pond, James Pond.
Also, be aware that there will be more inherent sight steadiness in a longer barreled handgun over a shorter barreled one because of the added weight and its forward location. Nevertheless, if your intent is 100 yard shooting, a scope will likely be an advantage no matter the barrel length. |

Totally agree that mechanically speaking, a shorter barrel will absolutely be no less "accurate" than a longer one in revolvers, although I can't be sure that barrel harmonics are to be considered in a revolver in the same way that they would be in a rifle.
Certainly, I can shoot better and more accurately with a longer barrel and I would have to guess that is due to the increased sight radius. Simply put, it can be visualized more vividly by trying to point at a precise spot on a wall with either a ruler or a yard stick. One little bit that hasn't yet been mentioned in this discussion... When it comes to a scope or other optic on a large-bore handgun, don't forget that the recoil forces subjected to it are EXTREME and you introduce one new thing with a short barrel and you exacerbate the other-- a shorter barrel typically means less weight, which makes it a bit more difficult for most folks to shoot it well and it definitely subjects even more pounding to the optic. So buy a Leupold or something with a lifetime warranty. The other thing you might consider if you are talking VERY short barrel is where the front of the optic is located in relation to the muzzle. Because I would imagine the hellfire & brimstone exiting that muzzle would simply wreak havoc on any optic that happens to also be near that muzzle. 7.5-inch barrel? No handgun scope will be near that muzzle. Snubby barrel? Maybe you destroy that optic in less than one box of ammo!

There are pistol scopes. They're designed for pistols. Where is the logic that no pistol should carry a scope? Or is it a personal preference that one would see extended to all others?

It depends a lot on the caliber and the intended use. Using optics can go a long way toward evening out accuracy. Trajectory at longer range can be compensated for by adjusting sights. That is with iron sights or optics.
The velocity may, or may not be an issue depending on the use. For paper punching, probably not an issue. But all magnum revolver rounds suffer significantly from shorter barrels. The published speeds you see are from 7.5"-8" test barrels. Shoot a 357 magnum from barrels shorter than 4" and you have a really loud 9mm load. |

Here you cannot hunt with a centerfire handgun with a barrel less than 5.5 inches. They orginally wrote the law to say 6", but later changed it when so many protested due to the numerous 5.5" Ruger models. If you want a real challenge, mount a scope on a Ruger MKII 22lr, and see how many squirrels you can kill. It will teach you how to HUNT vs just how to shoot

I don't like scopes (or red dots) on handguns, but
I use them to test loads (old eyes). They actually make very handy packages on short barreled handguns, and depending on the gun will weigh about the same as typical hunting handguns with iron sights. They can be shot very accurately with a bit of practice especially from a rested position.
. Here is a new S&W M69 (5 shot L Frame .44 Mag) with a 4 1/4" bbl and 4x Leupold pistol scope and Hogue 500 X Frame grips. It weighs 48.3 oz so equipped. A 2x Leup would be more practical for hunting and would reduce the weight a bit. . . Freedom Arms m97, 3 1/2" round butt, .45 Colt. The gun/scope are 5 oz lighter than the above S&W M69 (for a total of 43 oz). Very nice little package quite capable of 100 yd hunting accuracy. . . Not my personal cup of tea, but quite workable. .

Short barrels
I'm not going to get in scope rhubarb cause I don't use them on pistols. I have
found in quality guns, the barrel length has nothing to do with accuracy. I have sand bagged S&W snubbies and was surprised by the accuracy. I can't shoot them off hand, but the gun is capable. On the other hand I was young and dumb when I bought most of my magnum guns. I was into the longest barrel I could buy. Later I found I could shoot a 6" just as well as 8 3/8" Under 5" I start to loose accuracy off hand, due to sight radius. I have buddy that would put a 36x on a 25 auto if he could. He has a 4" m-15 with red dot that he can bust clays at 100yds all day, off bags.Take his bags away and he can't hit bull in butt with a Buntline. |

In theory a longer barrel should equal better accuracy , right ? Well you know what Yogi Berra said about theory !
I shot NRA bullseye matches with a S&W model 41, it had two barrels, a 5 inch heavy barrel and a 7 inch standard barrel . Guess which one I could consistently shoot better.....that's right the 5 inch. Same thing with a Ruger MKI Target, I had a 6 7/8 ( almost 7 ) inch tapered barrel, my friend had the same gun with a 5 1/2 inch bull barrel. Could consistently get better scores with the 5 1/2 inch barrel. So, in theory the longer barrel should get better accuracy but in practice, in my case at least, the shorter barrels got better accuracy. Have no idea why , it just worked out that way! Gary |
