357 Magnum | How Much Does Barrel Length Matter?
This video investigates the impact of barrel length on 357 Magnum velocity using a 3-inch and a 4 5/8-inch revolver. Chronograph data was collected for various bullet weights (110gr to 180gr) from different manufacturers and handloads. The analysis suggests that the difference in velocity between these two barrel lengths is not as significant as one might expect, with variations often being within a few hundred feet per second.
