This blog was requested by blog reader Joe, who wanted to know if choked airgun barrels are more accurate, and why. A number of other readers seconded his request. So, we know there’s interest in the subject.
What is a choke?
A choked barrel is one in which there’s a reduction in the diameter of the bore near the muzzle. Someone likened it to the FX Smooth Twist barrel that’s rifled only at the end of the barrel, but it isn’t the same. The Smooth Twist barrel has a constriction — the rising of the rifled lands. But in a choked barrel, the entire bore gets smaller. I don’t know if the Smooth Twist barrel is also choked; but if it is, that’s a separate thing.
