I wonder if the extra long barrel helps to shoot better.

Here's the 'MYTH' about barrel length ....the long & short of it
An extract from the experts -( AB Pelletier & Gerald Cardew)
Is AIRGUN barrel length important?
By B.B. Pelletier
•Barrel length DOES NOT determine accuracy.
•There is NO CORRELATION between barrel length and accuracy.
•A short barrel can be more accurate than a long barrel, or vice-versa.
•Length alone has nothing to do with it.
Pellet control is not the issue....
•The people who think longer barrels are more accurate often say it’s due to the greater control the longer barrel exercises over the pellet.
•Once the pellet leaves the muzzle, it doesn’t matter whether it has been in the barrel for 10 inches or 30; it is now a ballistic missile and subject to the same physical laws.
GERALD CARDEW an expert on air guns determined optimum spring gun barrel length as:
•A spring gun gets all of its “push” in the first few inches of the barrel.
•Only the first six inches of the barrel is needed for a spring gun to achieve maximum velocity.
•His experiments were conducted in the mid-1970s. Although technology has advanced since then, today’s spring-piston guns probably don’t use more than the first 10 inches of barrel for top velocity.
NOTE:
•Spring gun barrels are made longer than 10 inches because they are used as levers, as in break-barrels.
•On all rifles, a shorter barrel just doesn’t look right. That’s why the under-lever TX 200 from Air Arms hides its nine-inch barrel inside a longer shroud that also muffles the sound of the shot.
