Does PORTING Cost You Performance?
This video compares the ballistic performance of Hornady Critical Defense 125-grain .357 Magnum rounds fired from two four-inch revolvers: a ported Taurus 608 and an unported Ruger GP100. The test reveals a significant difference in bullet expansion and penetration, with the unported barrel yielding superior results despite a lower average velocity. The speaker, an experienced firearms instructor, was surprised by the outcome, highlighting how even a small velocity difference can impact terminal ballistics.
