"Brian10956"You can do tests and make them come out anyway you want if Barrel length was of no importance we would all have pistols with a 2 “ barrel. Military snipers would be shooting with something small they can throw away the 50 caliber Barrett and get a 5 pound rifle.

As I understand it, less accuracy with shorter hand gun barrel lengths is mainly due to the short distance between the front and rear sights, thereby making it harder to aim accurately.

The distance between front and rear sights is definitely a factor. With Air rifles most of us are using Optics were that wouldn’t be an issue. In my experience its more dependent on the shooter following the correct procedures than the hardware anyway. That’s why some of us can be more accurate with a pistol than others with a rifle. I have a S&W 686 in 357 6” Barrel that can do 4-5” groups at 100 yards, when I load with 38 it goes down to 75 yards.
back in time around the revolution they had barrel 6’ Long and they couldn’t hit a barn until they put rifling in the barrel. X
in reguard to Barrel length and accuracy. If you have a short barrel rifle thats accurate at 300yds. A long barrel rifle of similar build won’t be any more accurate at that distance. But as distance increases the ballistics will favor the longer rifle and the shooter is less likely to make an error in planning there shot. I got into Air rifles as I like long distance Shooting but I was forced to travel 3.5 hours to find 1000 yd range with a Air rife 200 yards is the same thrill for me as 1000 with my 6.5 creedmore sniper rifle.

Interesting discussion. No single test can take every single factor into consideration so I suspect there will always be people on both sides of the argument. But if we take it the extreme, if my gun had a 99 yard long barrel, I could be pretty damn accurate at 100 yards.

The longer barrel increase the efficiency of the gun. This means lower regulator pressure and lower HST. Less recoil and less air turbulence around the pellet all at the same velocity. 
Thats where the accuracy comes from. 

Hawkeye....I'm agreeing with you on barrel length and accuracy ...(45yrs experience with precision shooting of every kind)...benchresters agree that stiff and short is the winning ticket....winning Olympic air rifles all have a short barrel inside a longer tube which simply extends the sight radius.

Lock/barrel time is reduced with the short barrel (less time that shooter movement can affect the shot results in better accuracy).
Long barrels is a left over myth from the Harry Pope barrel era...in airguns more barrel mean more efficient use of the energy of compressed air..but FX smooth twist barrel show us that spinning the pellet at the last split second actually works...don't underestimate the effects of a quick lock time in extracting accuracy from any gun.

10x...Good points.

I’m not an expert in Olympic air rifle events but aren’t they over 10m ,free standing, .177cal with weight restrictions on the gun??

That is correct Michael.
In the Olympic rifle case the longer bloop tube increases the length of aperture sights' radius; and to an extent puts some more weight forward which acts as a lever mass to potentially make it more difficult to move the "muzzle" , from the standing position. Think of a tightrope walker's bar. (Harry Pope's rifles had similar outcomes but with the advantage of a full length solid barrel to give adequate velocity over his 200 yd target range).
The shorter Olympic barrel inside the bloop tube is not a handicap concerning velocity because adequate velocity for best accuracy (pellet static/dynamic stabilities are assured for the wadcutter pellets at the <600 fps and 10 metre range) is achieved.
Another possible advantage of the bloop tube, even in supposedly indoor range "still air", is to allow the pellet a little travel time in consistent repeatable intermediate ballistics zone air before exposure to other air currents. (As most would know, indoor ranges generally have air conditioning and fans for health reasons in a lead dust environment and so air is never really still). That tiny half mm dot at 10 metres off-shoulder is a tall order and requires every advantage to be squeezed out of rifle and shooter? No?

When taken as a whole, most things distil to a compromise and as with many other things, we tend to evolve towards the best solutions over time and with due regard to the specifics of the shooting discipline in question. Sometimes, for whatever reasons, the same end point may be reached with two seemingly contradictory approaches, the truth being within the other details.
Many good and valid points have been raised above by contributers to perhaps be viewed in the light of each shooter's own shooting circumstances. 
Kind regards, Harry .

I had made this gadget to extend the bipod towards the front of my Crown. It works with tighter groups.
