Thread: Fast twist barrels

Here’s article from Accurate Shooter on the topic Twist versus Velocities.

How Muzzle Velocity Changes with Different Barrel Twist Rates « Daily Bulletin

And here’s Frank Green's (co-owner Bartlein Barrels) comment that he posted on the Oz F Class forum re that article.

“Not only did we make all those barrels in the test but we chambered them as well. So same chamber reamer was used in all of them and the barrels where all made at the same time. If I recall correctly all of the barrels where made out of the same lot of material except for the left hand twist was out of a new lot. So about as identical as you can make them.

It's always been my understanding that twist might have a small impact on velocity but for the most part it really doesn't in the grand scheme of things.
