Revolver Velocity Versus Barrel Length

Lucky Gunner recently had a great article on Revolver Velocity Versus Barrel Length that I missed, and I recommend that you spend a couple of minutes studying their results.
Their results might surprise you. First of all, barrel length doesn’t matter as much as you might have thought, perhaps as much as 100 FPS for barrel lengths in the range we normally carry or shoot. You have to get really long barrels (such as for hunting) for the length to make any substantial difference.
Second, the +P loads do actually give you noticeably better performance (as much as 100 FPS or more) compared to the regular loads.
Third, as good as the +P loads do compared to .39 Special, they don’t compare to the difference you get with the .357 Magnum, which is as much as several hundred FPS depending upon bullet weight.
Lucky Gunner recommend that you test your own loads, guns and bullet weights if you want an accurate assessment. They also link this article where a table is included that has good data for your consideration.
