Generally not in air rifle.
Twist rate is easy to get for rim and centre but not many air barrels mention twist rate and twist = grain weight have a relationship in powder and to some extent FAC air maybe.
There are many things that make a barrel accurate but for air, length is not generally considered to be a major factor.
10 Meter precision may be different but that isn't my cup of tea.
That doesn't mean to say one should not seek a good barrel.
Again, the early AA S200's barrels were brilliant and on a cheap rifle. My Steyrs hammer forged barley twist was also excellent and I suspect that there would be a differential between the two units especially by the time it got to the retail end of the change and had passed across the water.
In a battle of wits I refuse to engage with an unarmed person.
To one shot one kill, you need to seek the S. Kill only comes from Skill
