Ruger GP100 Barrel Length Velocity Differences

I did some chronographing of a GP100 4.2" and 3" with different types of ammo. The results are interesting. Just that one inch of barrel length makes a difference when shooting magnum loads. Lighter, faster bullets will have more velocity gain in the longer barrel.
