interesting link, thanks.

Going down the page a bit further, and looking at the "real world" results, using the same Fed 230gr load, you can see slightly different velocities out of three different 16" barrel guns, and where a 3.625" barrel gun turned in a slightly higher velocity than a particular 5" barrel gun.

The actual velocity difference is insignificant, other than from an intellectual viewpoint. 50-60fps at pistol speeds makes no discernable difference in impact performance. It just makes a difference when comparing absolute numbers of fps, nothing more.

Looking at these numbers actually shows one real thing, and that's my point, while there are significant trends, it is the actual individual gun & ammo combination that determines the velocity you get from a given load. And what you get from yours can be quite different numbers than what a factory test, or the guy next to you on the range gets. It is usually not a significant difference in down range performance, but the odds of your numbers being identical to someone else's are slim. And since down range performance is what matters, differences of a few fps are only of academic interest.
