The energy loss in a revolver is minimal, regardless of barrel length. Cartridges especially made for snub revolvers, loaded with fast burning powders, still develop very close to stated velocities, even when fired in guns with the barrel removed, that is, fired direct from the cylinder.
I chronographed some of my handloads years ago, and surprisingly found some loads developed higher
velocities in shorter barrels compared to the longer barrel.
Bottom line; don't believe all you read, test it yourself.
